View Full Version : Is there a more versatile rifle than the LMT MRP.
In regards to caliber change, barrel changes.. Is this weapon the "best" out there..
I ask because my LGS has a "New" left over 09 model (confirmed by LMT) for $1400 out the door..
The only difference from the 2012 model is the 09 has the generation 2 stock on it...
Should I run & pick it up or is the a better rifle for the same money out there...
I will use it at the range, home, some classes etc...
Any help and input would be greatly appreciated.
Best Regards,
Jim L.

The new Colt .308 (CM901?) AR would probably be more versatile whenever they decide to release the damn thing. (Don't worry, it has"right around the corner" for a year)
But the real question is why? Why do you need a "versatile" rifle? Do you have a 1 AR15 limit?
The MRP weighs close to if not over 10lbs. That is ~3lbs more than a 6920 and while I'm not saying its not a good weapon (Trident, where you at?) it just appears that its easier to buy two weapons that are both dedicated in their respective roles than to have one "do it all" setup.
I've long given up searching for the best, for what is best for one person, isn't necessarily so for others, and it's often the case.
There are a few things to consider: will the weight bother you, are you really going to swap barrels and calibers, can your needs be served by another that doesn't have a monolithic upper.
For me, a little, no, yes. I got mine because I was at the time mounting my PVS14 on the weapon itself (instead of helmet mounted, as it's been for the last few years), so I needed a lot of rails on top, preferably one piece, not two. When the MRP first came out in 2004, it was the only such upper. Since then, I have built many other uppers with DD and KAC handguards, but I always take my MRP and to date, has had more rounds fire than all others combined, including full auto mag dumps in the AZ MG shoot :D
So all of my new toys always find home on the MRP. You can tell which parts are new because they haven't been painted yet :dirol:

Personally I buy MRPs first and foremost because I believe in their abilities as a single configuration rifle, their ability to shape shift within 2mins come secondary.
eta....MRPs certainly don't weigh 10lbs....here is one that weighs 7.44lbs empty:)

Mine weighs 10.8Lbs unloaded. I tried in vain to put it on a diet, went so far as replacing Troy sights with smaller KAC sights. After I removed the SF M900 and PEQ15, and extra batteries stored in the grip and stock, it was still heavy, it was then I realized it was the MRP itself that was heavy due to its heavier barrel profile.
I've since got used to it. I handled a bare bone LWRC carbine (no flashlights, IR laser/designator, maybe an Aimpoint T1), and it was just as heavy as my fully loaded MRP :fie:
That's a good deal on a great rifle.. Buy with confidence. It will serve you well.

My CQB MRP is my go-to weapon.
The monolithic upper eliminates any flex, heat stress or tension on the barrel, maintaining accuracy and providing an extremely rigid, versatile, and durable weapon system.
Weight can be minimized by carefully researching and selecting the right components. Magpul's CTR vs. UBR stock for example.

I personally feel it's the most versatile weapon on the market. I will be getting a 12" Piston MRP here in the next couple weeks, which will become my main go to gun. I love the idea of being able to switch calibers and such. Mainly out of desire to go to 300 BLK. Should make for a fun little toy too. To this day I still haven't heard a bad review about the rifle.

Simply nailed it:) Most people don't realize the vastly superior heat dissipation of an MRP/MWS chassis. The monolithic chassis is only half of the equation...equally as important is the ingenious method of capturing the barrel within a one piece chassis.

i dont see the point with barrel swap, mainly because you have to re-zero with every new barrel and that would get old quick, i would rather have dedicated uppers that allow me to just swap and go

The MRP weighs close to if not over 10lbs. That is ~3lbs more than a 6920
LMT lists the 16" MRP at 6.8lbs
That is a great price on an excellent rifle. I have been running MRP's for years and I really like the MRP chassis. They are very reliable, very accurate and I like being able to swap barrels and calibers...
With a T1, KAC BUIS, X300 and VCAS you are looking at a 8.5 lb rifle.

Zero's don't change that drastically. Your talking 2 maybe 3 clicks on a red dot max and little more in the finer 1/4 adjustable scopes. I confirmed this on both the rifle and CQB models using 10.5, 14.5, 16.5 and 18.5, 5.56mm barrels.
But if you are thinking of changing the barrel out in the middle of a fight you're smoking crack. THe idea of changing barrels is that it gives you flexiblity in caliber as well as length to fit your task.

The re-zero is not as drastic as you think. If I have an optic/barrel combo all I do is swap them together and when I reinstall, they're good.
I'd rather have a barrel/optic than an entire dedicated upper/optic. I also retain my light, grip, and panels.

Depending what you have on it maybe (Duffy!). Generally, that's not true.

Ever change the barrel on an AR?
It requires a lot more skill and equipment than the MRP does.
The MRP comes equipped with an "Easy" button.
The monolithic upper eliminates any flex, heat stress or tension on the barrel, maintaining accuracy and providing an extremely rigid, versatile, and durable weapon system.
It also really opens up optics mounting, reduces the need for cantilever mounts, and lets you mount aiming devices near the end of the rail without the inherent POI shift of most other HGs.
The MRP has a lot of associated win.
Not sure which LWRC model it was, it may have a 16" barrel. It may not have been 10.8Lbs, but it sure felt very close to it :blink:
I have removed the PEQ15 and SF M900, the weight reduction is negligible enough that I keep them both there. The PEQ15 doesn't weigh much. Swapping the M900 out for a TD stubby grip and a scout light wouldn't do much either, since the absence of any forward grip and light didn't decrease the weight perceptibly.
And since I have four SF M900 and just upgraded the head to KM4 (LED and IR), I don't want to buy another light.
If the weight bothers me enough, I'll get the barrel fluted, that would put a meaningful dent on the weight :)
Guys its important to note that not only is Duffy running a lot of gear on his rifle, but it is also a rifle length MRP not a CQB which is what I am referring to and to my knowledge so it the OP.
Setup like this it is less than 8.5lbs (and thats with a X300)
http://i156.photobucket.com/albums/t5/d90king/4286c00b.jpg
Even the piston falls right in there weight wise.

Isn't the rifle version only a couple ounces more?
I own a gen 2 Mega Monolithic Billet build and I think it could hold up well to the specs of a LMT MRP as far as rigidity, and flexibility plus space to hold your knick knacks....
LMT makes good stuff and at $1400 I'd buy that gun.
The monolithic rail has advantages - even if you have some extra weight.
As far as the quicker barrel change, that's is a solid bonus too. But really how often will you personally be changing barrels?

Ever shoot out a barrel?
Ever want a longer or shorter barrel for your application and don't feel like buying an entire new upper?
Ever think about changing calibers and don't want to have to buy an entire new upper to swap back and forth?
How do you know how valuable something is if you've never had the option?

I bought a lot of Winchester white box from which I have had several cartridges stick in the chamber just short of battery. With the LMT I unscrewed the clamping bolts and jerked the barrel out to clear the jam. I put the bolts back in and snugged them by feel and continued shooting. Very little if any zero change. I torqued it later at home. The LMT clamp bolts are a superior system of barrel retention.

Hi F2S,
I don't disagree with any of that and that why I mentioned it as a solid bonus of the LMT MRP barrel attachment method.

+1
It's also nice to have the ability to yank the barrel real quick so that the entire barrel and receiver/rail can be cleaned out if you happen to go shooting in the rain or get into some mud! No worries about rust developing in the mounting system.

I remember when considering my MRP purchase, the swapping concept seemed cool and would be something I might do. I never did...actually can't remember even thinking about it since I got it. But would I do it again? Without a doubt.
I personally have not seen an appreciable difference in zero with diff barrels. Once I know what the zero for my barrel is, I can go right back to it. Take the 16in out, put in the 10.5 and move the scope where the 10.5 should be. Usually pretty close.

The zero shift between my 16" piston and 10.5" DI is less than 2 MOA. So, I zero'd to the 16" reasoning I may take the longest shots with it, the 10.5" is for home defense mainly (and fun!). Even at 200yds (way further than any civilian SD scenario I can think of and longer than the average military engagement range...) that is only 4".
I also have a 16" stainless match barrel, haven't done anything with it yet. I'll probably sell the piston "kit" and keep the stainless. Then, one rifle and 2 optics (in return to zero Larue mounts) will cover the full effective range of the 5.56 from 0-600m or so. Pretty nifty for a 2 min swap (and less cost then another upper).

Fully loaded (as seen in the pic on the first page): 10.8Lbs
Sans PEQ15 and SF M900: 9.2Lbs
Sans PEQ15, SF M900 and TA31ECOS: 8Lbs
At 8Lbs, it has KAC front and rear sights, LMT stock (with four CR123 batteries)

I bought mine back in 2005 when I just wanted the long rails that the MRP offered. I never thought that I would have multiple barrels or use its modularity. However I now have three barrels and find its ability to switch barrels a huge plus. I'm actually toying with the idea of buying another.

I'm getting the rifle length MRP because I want the longer rail than the CQB version and the ability to swap barrels is also a big plus. I'm starting with the 16" CL midlength gas, but I think I'll eventually try an 18" SS and maybe a 14.5" barrel.
What three barrels do you currently have? Are they all 5.56?
KG_mauserman
03-01-12, 12:43
I have the 16" 5.56 barrel that it came with, a 20" 5.56 SS Noveske barrel that was made by Noveske for it, and a 16" .22 barrel that I got from spikes. It is currently running with the 20" Noveske right now. the rifle length handguard is the way to go. You cant run the piston conversion but thats not a big loss in my book.
I'd be much more interested in the MRP if it had a slick TRX / Vltor style rails. I really like the concept otherwise.

I had a small problem with the used MRP I picked up, but since fixing it, all is well. I love this system.
But as stated on the weight thread, mine came in about 10.5 lbs. Why? I'm running a heavy receiver and a UBR stock. But I like a beefy weapon for ranch defense/homeland defense.

That's a great start. Ideally they'll end up like the new Noveske handguard, but for now I'm glad that there is an MRP option closer to what I want than the standard option. How much does the slick railed version weigh weigh vs the standard MRP upper?

Everyone seems to talk about the weight. It's almost all in the barrel (the receiver itself doesn't add that much). If you want to slim down an MRP just pull the barrel and send it to ADCO or similar and have them reprofile it to a lightweight.
Then you have the best of both worlds.

What was the issue you had? Was it the mating of the MRP to the Noveske lower? I definately had some issues with that. WAYYYY too tight at the pivot pin.

That looks awesome!
If there isnt a noticeable weight diff I may wait on someone to dump their old chassis.
Anyone know a release date?
Ok, I have a question on the MRP that's a bit more legal oriented - but I'll throw it out on here.
I'm from MI which means no SBRs. However I'd like the ability to have an SBR for training out of state. We can have "pistols" here, which means no stock or VFG. However the lower must be registered as a pistol.
The MRP seems like a sweet package to have the same set up, but the ability to go from long to short. Any Legal Beagles out there who can help on this? Is there ANY way to have an SBR for out of state training?
I'm ready for the "No"s as well. The way I see it, I can't own an SBR in MI, and once I left MI for an SBR friendly state, it would still be unregistered as an SBR. Correct?

Correct. There is essentially no way for you to own an SBR. You could get yourself a pistol lower, and then legally speaking having a short barrel in your home would be ok as you could take the upper off the rifle, put the short barrel in, then throw the upper on the pistol lower. If you leave Mi, however, you would not be able to use an SBR as, like you stated, it would then be an unregistered SBR. Time to move my friend!

For mine, it is actually loose. The problem originated with the bolt catch rubbing up against the bolt as it cycled, causing FTF's. Removed the BAD lever, took the barrel out and cleaned it, polished the feed ramps, and reseated the barrel back in with a good tap from the rubber mallet and problem solved.
Heavy beast, though.
