LMT has said the 300BLK barrels won't come out until there is sufficient commercial ammo for testing. So conversion remains the only option for now. Love my Noveske 10.5" 300FB within 300BLK spec. May put on an adjustible gas block as Todd said the gas port is too large to take full advantage of supers (my pre 300BLK barrel will be over gassed with supers). 762-SDN-6s have shipped and I am waiting for mine! Check out the Effeto Mariposa wrench storage option below. I think its ideal as it tops out at 141 so no chance you break a bolt... also just look at the thing... art. Barrel pic below is old but have 8 for the 2 MRP CQB uppers and 2 for the MWS (308 & Noveske 6.5 Creedmoor). Planning to convert an 18" mid gas 6.5PCC (223 parent case wildcat that will share projectiles with the Creedmoor).

Nice! What is the 2nd barrel from the bottom? It looks like it has a Noveske Switchblock.

It is a standard 12" LMT Piston barrel group with block in the mid position. Look at the missing gas key on the carrier. MRP CQBs will fit Noveske switch blocks on mid length barrels though as they will be exposed just like on the LMT Piston barrel groups. I plan to get one on an 18" mid gas 6.5PCC wildcat.

Nice, Which scope is that on the MWS?? I have been looking hard at Leupold or NF for mine.

Thanks. Bushnell ELITE 4200 6-24X50 (426245F). Its front focal mil/mil but does not have zero stops so I made a physical one. I think it cost me about $750 + shipping which is probably about half of a NF but certainly would not advise against one of those. I do think mil adjustment and front focal plane are the way to go. In addition to the lack of a zero stop this scope does not have much elevation adjustment but fortunately I have it in a Larue 50bmg mount with 30moa built in. If I remember correctly I think I have 14 mils of elevation from my 100 yard zero with the 6.5 Creedmoor barrel installed. Another cool thing about MRP/MWS monolithic rails is that you don't need cantilevered mounts and can use rings without any issue.

Spikes 22lr conversion and barrel. Cool to be able to run 22lr in the same setup / weight / trigger as your go to gun without running 22lr though your primary barrel. Locks back on last round but drops when you pull the empty. Have to check if the cmmg fix to keep it back and drop bolt on next mag will work with this.

Very Nice!

May I ask exactly what model the Effeto Mariposa wrench is and where you bought it? I did a quick google search and found a lot of places with many different models. Any good gouge on where to pick one up?

You've got me thinking now with the ever rising cost of rising ammo. Burn a ton of 22lr, pull out the wrench change the rifle back to its fighting configuration verify zero before going home and call it a day!

This is a Kestrel bikes branded "Pro" model that comes with a free $50 re-calibration (they suggest after 5000 clicks / torque jobs). With the store wide discount coupon it was $190 shipped and included 2 water bottles. You can get a basic black model without bits for $150 + shipping from another seller.

Thanks for the tip on the wrench. You have quite an enviable collection of barrels there! I have to ask, what is your impression of the work done by DBMG? I've been considering a SS Noveske Barrel to make an SPR out of my MRP but I've seen other post by Trident saying that the LMT SS 16 inch is the best barrel he has ever shot. I would have to get it bead blasted or refinished but it would still be less than the Noveske I guess. I know ADCO bead blasts for lke 15 bucks.

Last question...for now. I didn't see the 22lr MRP barrels at Spikes. Does anybody know if they still make/sell these. I emailed them but no reply yet.

No problem. I have been totally satisfied with DBMG's work. Just remember that no gas tube retainer is added to the chamber end so you have to be more careful with them. Might be hard to justify the premium to convert a Noveske 556 vs price on an SS from LMT... its an easier decision in 308 because LMT is charging $700 for those and you are close to the same total price with a conversion. Conversions also make sense for 6.8 because LMT is sticking with the old specs. A mid gas Noveske 6.8 with factory switch block would be a fun but expensive proposition. Also remember that you could convert anything... possibly a Kreiger.

Just put an PRI adjustable gas block on my Noveske 300BLK and the adjustment is perfectly accessible without removing the barrel (lucky). I plan to shut gas off for fast powder ultra quiet single shots (that won't cycle fully anyway) and open it fully to cycle slower powder subs. Could also tune for best balance for supers but that is not my plan for this barrel. Might file on the block a bit as it looks like it barely touches the upper.

Won't get a chance to try it until next weekend.

Any thoughts on PRI vs JP adjustable gas blocks? Are there any others out there?

I was looking for the lowest profile and PRI looked like the way to go for my need. I don't have experience shooting with any yet. Saw a guy use a JP A2 fixed for a Retro build in 300BLK that looked really good.

Think JP and PRI work the same. Apparently Jet suppressors make one (AR performance has 2 closeout). Also Paladin Machine makes a 3 position block that looks a little less refined from what I have seen. Would have gone with Noveske Switchblock but didn't want to cut up my MRP upper and can only put one of those in the mid position beyond the rail.

jasonusvi
06-26-11, 20:38
I tried and was disappointed with the PRI this weekend as it still allows enough gas to unlock the bolt and push it back an inch even when fully shut. May look to get an push button on / off block that apparently Marty has made in the past.

Separately, had ADCO fill and re-drill the gas port my overgassed 14.5" SS LMT 6.8 and its much improved. Does not feel so rough any more, deposits brass at 3 with an H2, and no more extractor marks on the brass with the same load.

Still getting about 1.2ish 5 shot groups with Nosler factory second 115 cannelured HPBTs over H322 but have not worked up loads. I think this is probably good enough for a relatively cheap projectile over dropped powder. 100 yards, 10x bushnell in a Larue, harris bipod, SSA, no bags.

That is freaking sweet on the KAC lower w. the LMT upper....as you know, that is how I roll.
I sincerely appreciate your commitment to the MRP/MWS platform/system as you have truly tapped into that wealth of magical powers these guns potentially can employ, and by extension your exploration was shared by all other MRP'rs.

If you have a creative mind, and a natural ability to shoot...nothing compares to the MRP/MWS...that said, if you just want an awesome rifle...plenty of cheaper and more easily had options like LMT, Colt, BCM, or DD's standard M4 type rifle. Astronauts buy MRP's and MWS's simply to have the vehicle to explore outer space!:cool:

I just got done doing something very, very nasty w. my MRP SPR...video should be coming tonight:)Did you post the video?

Pulled my Geissele Service Rifle trigger and put it in the SR25 lower, installed Battle Arms ambi safety, Phase 5 lever, MIAD grip, and Sopmod. Some dremmel work needed on the Phase 5 near the thick paddle area.

Now my MWS ergos match my MRP. Will look to improve Noveske 6.5CM barrel groups with this trigger.

Thanks. That trigger had gone unused for too long in my Service Rifle. I suppose I don't have the inclination or time to compete so its time to sell the upper (Compass Lake w/ Krieger) to fund something esle.

Had a good LMT customer service experience recently when I learned they are now shipping piston guns with 2 position gas plugs (Fire / Suppressed) vs the single position (or Fire / Off) that came with mine. Called them up and they put one in the mail at no cost... I did buy the 12" piston kit directly from them some time ago.

The 22lr conversion is a blast and a good option at my indoor pistol club when the weather sucks. Heard something about them not making it anymore... would be too bad if true.

Only downside of MRP/MWS is having too many options! I've got so much load development / testing work to do. I got my best 5 shot (I know I should step it up to 10) with the 6.5CM using undeveloped hand loads and dropped powder a while back (0.66"). Perhaps I will shoot more consistently with this trigger and when I start using a rear bag rather than my left arm for support. Converting 308 brass to 6.5CM looks like it will work fine but need to pick up a neck turning tool for a bit of thinning.

MWS at 1.43 and 2.31 into this video of British Royal Marines in Helmand. (http://www.liveleak.com/view?i=6d8_1312163187)

6.5CM results yesterday with KAC lower, 9mm heavy buffer, and Geissele. Best of those 4 five shot groups is 0.65". 120 Lapua Scenars over dropped Varget. The high shot on the bottom left target was the cold bore shot. Still looking to find a load and improve technique so that most 5 shot groups are under an inch.

Thanks! Was a blast on Saturday. In addition to the 6.5, 45, and 12" Piston, I threw the 10.5" Noveske 300BLK barrel in the MRP and put the 45 suppressor on (still waiting for the AAC!). All 50 of the 175 subs cycled flawlessly from a GI mag.

I also tried some 145 tracer subs that I didn't expect to cycle but amazingly enough they did. Several of them also lit and the red glow burning out in the berm surprised a few. They are so cheap I just wanted them as plinkers but guess I should glue over them to keep them from lighting. Would also be fun to punch holes in the copper lining so they all light earlier. Spitting suppressed "fire" at dusk would rock.

I'd love to hear more feedback on the 6.5CM barrel. Why did you choose it over say a 260 Remington? I'm trying to decided on .260 Rem or 6.5 CM...

Also, why did you remove the threads? How much better is the Geissele trigger versus the 2-stage LMT that came with the rifle?

08-30-11, 23:09
I appreciate the reasonably priced factory match ammo and have read that feeding is better and that you can load projectiles longer. Also read that it may be slightly less a barrel burner and hence some additional useful life. Another significant reason I leaned to 6.5CM is because Noveseke made one (and don't make a 260 currently). I think I like the 3R 1x8 spec better than the 1x10 I believe LMT is scheduled to release based on the SHOT pictures.

I really like the set up. The results you see are my first with the trigger and it is very crisp. I don't have a ton of experience however so can't claim to feel a massive difference from the factory trigger.

I took the threads off because I converted the barrel before I invested in a preban SR-25 lower and unfortunately live where that matters. I do like that its only slightly longer in total than my 16" CL with a permed battle comp. I will likely un perm the battle comp will be able to use the 762-SDN-6 when it finally arrives.

Good luck with your decision!

Thanks for the info - I have heard the issues with loading bullets longer in the 6.5CM vs the .260 Rem. Why do you favor the 1x8 vs the 1x10 twist? I would think the only difference for Noveske making a barrel in .260 Rem would be the reamer used...

Gotcha on the threading...

Some badass options pal, what is that 6.5pcc all about...what's the max effective range off it? how accurate of a pill can it be?

Thanks for sharing:)

Thanks. Should push 120s to about 2400fps and 100s to 2600fps. Goal is to get close to 6.8 performance / range with assistance of high BC while maintaining 556 parts compatibility. Hope dies don't take too much longer. Guys who initiated the project are going to get me some rounds for velocity and accuracy testing.

ETA: Barrel is a BHW 1x8 3R Poly. 1x8 3R is the same spec Noveske uses for 6.5CM.

I have been trying to get a scar-17 for about a year, When I went to the gun shop last week the owner told me he got a lmt mws in and it looked like a pretty nice 308 but I didn't know much about it except that the British adopted it so I bought it. I told the dealer to see if he can get me a acog ta11-308 for it. Well the gun shop called back and said one of their distributors have the Acog but they also just got a scar-17 in. Well there went my Christmas money an lmt mws acog and scar-17. Now I have heard so much good things about both rifles, I will probably keep both and sell my HK-91 instead. If it stops raining enough I will take them both out to compare. But just holding them the Scar-17 seems a lot lighter.

Will a SCAR take a Geissele? How much is a spare bolt? I still think there is value in parts compatibility and there are more compatible parts in circulation and being produced for 308 ARs (including ability to use many standard AR lpk parts).

MWS would probably still be heavier but weight would be much closer if you turned down the MWS barrel to the same profile as the SCAR and added rail length to the SCAR to match the MWS real estate.

If weight was my primary concern Id probably go with the Larue Predatar (if not a 6.8).

Selling the HK91 sounds like a good call.

Please stop comparing the MWS and SCAR 17s. Two very different guns that are designed to satisfy different sets of requirements. This comparison only causes heartburn and strife in an otherwise informative thread. If you have to compare the MWS to the SCAR, you should wait for the MK 20 SSR to come out. If you want a precision gun buy the MWS, if you want something to replace the FAL with, buy a SCAR 17s. Also, Geissele makes a SCAR trigger though it’s rarer than hens teeth and priced accordingly. My plan is to shoot my stock 17s trigger into compliance.. I’ve heard that they smooth out considerably with use.

There have been attempts by folks on this board to create a “skinny” WMS through material removal with limited success. Much of the weight appears to be in the barrel extension/mounting apparatus. Can’t take material from there. It was concluded that one should buy and use the MWS for what it was intended for and not to try to turn it into something it isn’t. FWIW, the weight of the 17s with the PWS extension is right at 8.5 Lbs. The LaRue Predatar is an attractive option too.

Robryan, good move on buying both. IMO, selling the HK91 would be a mistake. Yeah, it's an outdated turd but you really need one of everything…

And yet you continue on with the comparison. :rolleyes:

Also, Robryan is the one that initiated the comparison, not Jasonusvi, who as the OP, should have a little leeway in which way he wants the thread to run.

Going on the FN site some that have both scar-17 and lmt say scope the scar-17 with the acog and the lmt-mws needs more magnification so I put a Nikon Monarch 2.5-10x44sf that I have and if it shoots good enough I may change it out and put a Nightforce 5.5-22x56 but that scope is huge and would probably make it a bench gun. I would also have liked on the LMT if they put a folding front site instead of the screw on one as you almost have to remove it to use with some optics. Also on the FN site a members claims he was getting sub MOA with the stock LMT-MWS barrel and now get 1/2 MOA out of a 18" stainless barrel. I bought 4 magpul magazines for the LMT-MWS for 19 dollars each and I will probably be stuck with my one Scar-17 mag for awhile as they are over 80 dollars each if you can find one.
Going to keep my HK-91 that would be a good standard to compare both rifles to.

Only in so much as to support my argument that the two rifles answer completely different set of requirements and therefore, one should not be considered a one for one replacement/substitution for the other.

Fair enough.

That’d be a good approach. Not exactly the same, but I’ve currently got Leopold MK4 LRT on a Noveske N6 and a 1-4 Trijicon TR24 on the SCAR. I’d like to upgrade optics on both (NF and S&B respectively), but I have a bad habit of spending money on new guns when I should be spending money on new optics! The N6 is a tank.

No doubt, especially with a SS barrel, the MWS will shoot good enough to satisfy your justification for funding a NF.

It'll give you an appreciation for your modern 7.62s. Perspective is a good thing to have. Shot my HK for many years before trying other things.

My Gen 1 MRP with Surefire 60 that arrived today (going to add a 7.62 MagPul for drop protection). Larue dual flashlight mount but using a ring as a forward sling attachment point. I've got Noveske QD end plates on everything.

Looking awesome pal...have you had your gen1 chassis since the fall of 2004/spring 2005?

Nope. Bought the upper with a well used 10.5" barrel with surefire brake in early 2010. Prior owner was LE with training responsibility out of VA who had run an estimated 5k (about half suppressed). He was moving to matching BCMs for training / patrol.

I sold the barrel and ordered the 12" FA piston kit direct from LMT. Instantly hooked. Started picking up more lightly used barrels. Got an MWS and sold my starter DPMS LR-308. Became aware of the DBMG conversion and got the Noveske 10.5 300FB done a month before 300BLK was introduced. Ran the 12" at an EAG class in Culpeper VA with zero issues (despite running Brown Bear) in Sep 2010.

In fact, guys in my EAG class were going to attend Modern Day Marine following the class. Coincidentally, that is where news of 300BLK was first released if I recall correctly. Was a little pissed about the conversion before Todd said the FB chamber was in 300BLK spec. Port is a bit over sized but have an adjustable on for now (may get the port filled and re drilled).

Couldn't resist this AR15 EE purchase for $350 shipped... will take better pics when it arrives. 16" barrel chopped and BABC pined to 16" OAL.

Now that I have the preban SR25 lower will send my original 16" CL (also with pined BABC) to get unpinned / BABC for something else. Will put on a 51T to get it ready for the 762-SDN-6.

May also send the new shorter barrel for a turn down to lighten it up further.

Any intrest in selling your SR-25 upper??

I would consider it.

USPS lost the chopped barrel above. Seller already sent back the money but I will happily send it back again if the barrel turns up.

Have to tap the pins for my LMT MWS upper but it works. Should also work with MA-TEN, Larue, and of course KAC 308 uppers (all angled). When will all the 308 guys start selling uppers?

Still have to remove the pinned BABC on my 16" 308 barrel to make way for a 51T mount. I would not own this if I did not live in a ban state but glad the components / ergos match my standard AR lowers.

Finally got a replacement barrel converted and sent back to me. BHW had botched the first chamber but took care of it. Barrel is an 18" mid gas 3R polygonal 6.5PCC with a Noveske switchblock and 51T hider. Hope to function test and chrono a few rounds this weekend.

Just some pictures from my outing this morning. Grey and drizzling in the 40s.

Decided to try a 25 yard POI shift test today swapping barrels and not adjusting the T-1 zeroed at 50 yards for the 12" 5.56 piston group. The 25 yard test was rapid fire from the bench / no bags. 10 round 300BLK group is not good but was dropped powder (LEE powder drop) under pulled 175s and do think of them as low cost subsonic plinkers... have had much better results at longer distance with Hornady 225s.

In total shot 90 rounds of 300BLK 175grain subsonic plinkers (10 on paper). 1 troy mag, 1 newer windowed pmag, 1 GI mag. No failures.

Shot 80 rounds of 6.8 115 grain HPBT Nosler 2nds (10 on paper). 2 Barrett 30 rounders, 1 PRI 20 rounder. 1 Barrett shot clean. The other and the PRI did not lock back on the last rounds.

Shot 90 rounds of 5.56 Silver Bear (10 on paper). 1 Sure Fire 60, 1 pmag. No failures.

Shot aprox 120 rounds (mixed Tula and reloads) of 45acp from brand new S&W45. No failures.

22lr barrel is in the picture but left the loaded mags at home so it got no use today.

Was fun. Glad the 6.8 was on top of the 5.56 (at least at 25yard) and that the 300BLK subs appear not to require windage adjustment. Glad the Surefire 60 ran without a problem its first time out. Glad the 300BLK reloads ran with no issues and locked back on all 3 mags. Was disappointed the 6.8 didn't lock back on the 2nd Barrett and my older PRI (on which I attempted a spring tweak since the last outing).

Had a blast hammering steel at 50 & 100 yards with both the 300BLK and 6.8.

Will try the same POI test with the 3 barrels at 50 & 100 next time and see how much things open up.

FA Piston BCG, FA 6.8 BCG, SA BCG for 300BLK - H buffer for all.
