Might actually be decent. Better than the SIG I hope.

Might actually be decent. Better than the SIG I hope.
i bet its $2500
sweet though
Fully ambidexterous? Funny, I can't seem to find the left side magazine release.
I bet they are going to regret that gas-block placement of the MBUS.
Is it a monolithic upper? Looks like it.
I wonder how LMT will feel about this, and it will be available in the US with that upper.
Looks cool, but wish they figured out something with the gas block so it was lower profile with no rail on it
As the article suggests, it seems like a unique design and it does seem to compete. I'm looking forward to seeing where it goes.
Jason, it's spam/trolling. TFB actually might get more classy soon, too.. which is the irony.
On topic:
Will this be a contender against the 416 or are quick change barrels not important?
Some comments of one of the developers:
Quote:
There is no POI shift if you dismount and mount the same barrel. There might be some shift with other barrels (same length). And there are shifts for sure if you change the barrel length.
Why a (real and quick) barrel changing system? Or better: possible benefits:
- Its easy to clean (no fumbling around in a barrel extension, etc.). I like this feature on my AUG
- You can easily clear some types of malfunction (e. g. stuck case, broken case, ... you name it)
- You can go from CQB length to DMR length quickly with the core of the rifle staying the same (I know.. there might be no reason to do that in 5 seconds, but as a side effect you simply can).
- Quick and easy caliber changes are possible by just changing the barrel and the bolt head. Thatīs done within 60 seconds. The STM556 will be offered in 5,56, 7,62x39 and .300 Whisper for now. More to come. Barrel legths will be: 11,5", 13", 14,5", 16", 18", 20", and 22".
- Because of that quick change system they are thinking of lMG versions in 5,56 and 7,63x39. Could be interesting.
Probably there are more advantages. And if you see no benefit you can just treat it as every other rifle.
The barrels are cold hammer forged, chrome lined and MANNOX coated. Also every other steel part is MANNOX coated.
The gas settings are:
- normal use
- heavy use (weaker loads, dirt, temperature, etc.)
- silencer
- off (for barrel grenades and if you need a silent shot with a can without any motion of the bcg (think of .300 Whisper)
The gas piston, which is a 35 years proved system, kicks a rod that is located in the handguard and can easily be removed, when the barrel is off. There is almost no dirt or carbon build up on this rod after heavy and sustained fire.
The handguard/upper receiver is monolithic and made of forged 7075 aluminum. 3 reasons for the monolithic design:
- optics
- barrel change system
- use of grenade launcher (have you ever seen high speed footage of an AUG mounted GL shooting a 40mm?)
The ventilation holes on the side of the handguard will all be able to receive quick detach sling swivel attachments. Additionally you can mount different Picatinny rails that come with a cable slot (like the side AUG A3 rail).
The safety catch will be able to be also engaged when the hammer is not cocked (some mil regulations want a rifle to be on safe before loaded).
The most interesting thing is still in the experimental phase: They want to establish a permanent dry lubrication system in that rifle. This will also be possible due to the piston system, because heat is generated at the front end and not in the bolt carrier group.
Additional remarks:
This rifle is still a prototype! I just wonder how many experts are on the internet (especially on german forums) who are discussing wildely just because they see a picture of a prototype.
Will this rifle be a toy for the overindividualized civilian who wants to change the handguard every other day? Probably not. But therefor it is also not designed to.
Will you be able to shoot it "Costa-Style" (sorry). No. But a longer handguard is planned/possible as much as I know.
Yes. After 5 Magazins of rapid fire the front end gets hot. But handling is still possible. And if you use a VFG you have absolutely no problems. And after that ammount of ammo you can still touch the bcg. And there was no cook off. BTW: I own a DI SBR with a Troy TRX Battle rail and I too donīt want to touch it at the front end without gloves after 5 mags of sustained fire.
Regarding the serial numbers: In Austria (were the rifle is manufactured) only the barrel and the bolt head are considered as weapon parts. The lower (and the rest) you can buy like bread at a bakery.
The part about being able to touch the BCG makes me laugh....you can do that on a DI BCG after 5 mags as well :jester:
The heat difference is one thing always blown way out of proportion. The only part you do not want to touch is the gas key...now that will be hot.
also this part: The most interesting thing is still in the experimental phase: They want to establish a permanent dry lubrication system in that rifle. This will also be possible due to the piston system, because heat is generated at the front end and not in the bolt carrier group.
will never be possible, guns need lube thats all their is to it and the minute heat difference between DI and piston will not make a difference one way or the other regarding lubrication in a AR-15 platform rifle. When sand and other contaminates get brought into the mixture Lube is a necessity for any rifle based on the AR platform.
Thats quite contrary to what Larry Vickers has said about the DI system. He thinks heat is a huge problem that affects bolt life, etc.
Well there is testing on this very site that shows the difference is generally 40*F at most on the bolt. Certainly not enough to be any issue.
I have also personally put 800 rounds o wolf through my AR-15 in 1hr and had to pull the bolt to remove a broken case thanks to wolfs great quality.....it was just warm to the touch.
you make your own judgement.
I just want one for my personal reference collection, not as my go-to rifle. It is an interesting design and made by one of the premier European small arms manufacturers.
What other SBR gas pistons are out there?! DD doesn't sell any, KA doesn't sell any, LWRC nope, BCM nope... I need some assistance here guys...
I think they missed the piston craze by about a year.....
Back on topic, is the chamber separate from the barrel assembly?
I would guess not. At first glance, the barrel from that puppy appears to be the same (or at least, the same design) as the one in the AUG.
If that's what they've done, then the interest should be on the barrel and the mods, not if it has a piston, dissipates heat, or other whatever else.
Maybe they are positioning themselves for some kind of quick-change-barrel LMG future.
Quick change barrels are pretty pointless. If you are using your AR-15 as a LMG your doing something wrong. Not to mention all quick change barrekls have some form of POI shift which is not wanted on a carbine.
For repair it may be a bit faster but changing the barrel on AR-15 is pretty easy as is.
I have been but I've must have misread LWRCs site. I've already checked out the major manufacturers that I am familiar with. If LWRC does sell gas piston SBRs can you please point me in the right direction, instead of typing in a pointless non-helpful comment like a child on Youtube... Thank you.
So, quick change barrels that require only a few bolts to swap, plus a gas piston.
Sounds a lot like the SCAR-L.

Are you sure about that? I run the 7.62 H&K and what I do is replace the lube on the BCG after 300-500 rounds. I use literally 4-5 drops of oil (it is enough) which I wipe off from the BCG after few range trips and put new oil on it. I wouldn't need to, but I can't see any harm in doing so. I do it mainly to clear the brass shavings off the bolt head.
Are you sure you could lube an AR-10 in a similar fashion?
Not sure about the AR-10 as I stick to 5.56 guns. I do know a few drops will easily get you by for thousands of rounds in a perfect environment with the AR-15, but if you are goin to be in a very sandy area extra lube is needed and it would be wise to wipe out the sand daily.
In a perfect environment you can run an AR-15 bone dry for a while with no issues. I believe Mike Pannone got to around 2,400 on a bone dry system when testing things out.
When you start adding things like sand, grass, mud, snow, ect that is when issues happen and why you should clean out that stuff daily.
Can't we just make a sticky thread, "The huge piston AR bashing thread" for example, where the people who feel the need to bash piston AR designs can blow off some steam every now and then? Instead of having every thread regarding a new product accumulating a shitload of posts, saying the following ad nauseum:
-Piston AR's are stupid/suck/<insert adjective here> bla bla bla
-All guns need lube, even pistons...bla bla bla
-Temperature differences between DI and piston is minute....bla bla bla
Everbody knows that the oprod design incorporated to the AR platform is viewed as unnecessary, with little to no benefit and a lack of industry standard, here on M4C. But honestly, having this happen in every god damn thread is getting quite old and reminiscent of other less professional boards.
Based on all of the threads on this board about DI AR's experiencing problems, one could draw some pretty damning conclusions about that system as well. But, as we all know, most problems stem from user error/incompetence, lower quality parts, worn or damaged parts, bad ammunition etc. Not the operating system.
It's getting ridiculous.
For a unit utilizing an armory concept, swapping barrels based on METT-TC analysis and re-zero before mission launch could be more cost effective than having two separate uppers (short/long barrel). re-zeroing is not going to be a time consuming process, and POI change is not going to be extreme.Quote:
Not to mention all quick change barrekls have some form of POI shift which is not wanted on a carbine.
It is most likely not meant as an in-mission barrel swap feature, or utilizing the carbine as a sustained fire support platform.
