LMT .308 MWS

[Ichi]

Thinking about buying a Hux can for my new LMT, or just putting a BRT tube in and running my Ecco modified 762-SDN-6.

For those that have one, is the Hux can worth it and how does the rifle run with it?

I'm happy with both the HUXWRX Flow7.62 Ti and the BRT 0.086 gas tube.

With the BRT 0.086 gas tube, the factory LMT buffer spring and a 1 oz buffer, the rifle functions without issues when shooting both unsuppressed and suppressed with the FLOW 7.62 Ti.

I'm able to use this same combination when shooting both 20" .308 and a 24" 6.5 Creedmoor barrels.

The HUXWRX Flow 7.62 Ti does not change the ejection pattern when shooting either calibers. In my case the shells are ejected at 4 o'clock and tossed about 5-6 feet.

 

[unclemoak]

@unclemoak what’s the speed difference you’re seeing between your 14.5 and 16 in Creedmoor barrels?

They all sold before I had a chance to even shoot one.

I will say there’s only like 90fps difference between my 14.5” mrgg-a and a factory 20”

Okay, so long story short, I bought an LMT MWS quad rail in 2017. Sold it a year later to help fund my wife’s engagement ring. (I don’t regret that decision, I got her the ring of her dreams and she is the kind of wife every man dreams of. She asks for very little and I’m glad she got the ring she wanted.)

Anyway, life got busy, work got crazy, kids, all the stuff. I have been out of the shooting world pretty well since about 2020. I have off and on always said I wanted another large frame AR, with the LMT being the top of my want list.

With current political stuff I decided if I was ever gonna get one, I better do it now. So I ordered a MARS-H 16” 308 from Titan Defense and am excited to get an LMT back in my hands.

So my question is, I’m wanting to set it up as a DMR rifle, as I already have a nice long range bolt gun. A DMR type setup, capable of 300-500ish yards would be perfect for coyotes in the fall while farming.

Since I have been out so long, my head is spinning as to what my best options are for scopes and suppressors.

For optics I’m looking at scopes in the 3-18ish power range. Two stand outs to me seem to be the Leupold MK4 or Eotech Vudu.

Suppressors is where I really get lost. I am kind of looking at the Q Thunder Chicken or Trash Panda, but I don’t really have a solid reason why other than one YouTube video I watched that was the can he had on his LMT. I’m wanting something that I can also put on my 5.56 ARs as well, so preferably not overly long or bulky. Just something to make it a reasonable amount quieter, and hopefully not make me eat too much gas.

When I first got into long range shooting at 17 years old, this site helped me out a lot. Now many years later I am once again feeling like a beginner asking for suggestions. So fire away!

Do some research on pewscience for suppressors. That’s the best place to get a feel for what’s currently out there. Do be aware that Jay’s test host for .308 is a bolt gun, so pay close attention to what he calls the Omega metric; that’s the back pressure value. It’ll be important for gas guns. Take a look at Specters CAT JL or the PTR Vent 1 for the latest in tech and highest performance.

As far as using an AEM5-30, you can just machine the i.d’s of the AEM bushing to match the o.d’s of the barrel. A 16” factory barrel works perfect. The can in conjunction with a BRT 0.067 tube is surprisingly well behaved

Has anyone here had any experience with the MWS Piston 7.62 rifle? If so how are they, good/bad ect…

The reports I’ve seen have had quite good accuracy.

To my surprise, when I weighed a piston barrel and bcg, they are actually lighter by a few oz over a standard weight barrel and bcg.

What's everybody's preferred lube for the MWS ? I mostly use Lucas gun oil or just CLP.

Unicorn blood and orphan tears.






I use Lucas oil too. Slip2000, any other live I've accumulated. I do use grease on all the heavy wear surfaces though. Cam pin, bolt pads, gas rings. Oil everything else.

I have some white lithium grease mixed with some moly, would that be good on the high wear areas ?

Same. Slip 2000 has been my go to

I have nothing scientific but between the fingers I feel it's got a slicker and "stickier" feeling than most others. I feel like when I put it somewhere it won't get shot out in a few rounds.

As far as grease goes I use shooters choice. I've also used bearing grease in a pinch. I'd opt for something less viscous especially on a large frame. Depending on the lithium it might be too thin.

Edit: this is my limited opinion. Someone whose tried more might weigh in differently.

Bought some Bexar Blood to try and have been quite happy with it.

Might be a little lazy here but...

For those who have cut their 16" 308 barrels to 14.5 what has been the velocity drop you've seen? Pre and post fps? And down range accuracy changes at the 700-900 mark?

While not exactly 14.5in, my factory 13.5in SS barrel shoots Federal GMM 168's at 2415 and GMM 175's at 2337. As long as I get my wind right, it's surprisingly accurate out to 1000-1100 yards.

It doesnt fall off as much as I thought. My 16" runs FGMM 168s at 2456. Figure a 14.5 should roughly run 2435ish, fairly negligible. Thinking of having my 16" cut down and pin/welded at 14.5 or whatever it would take to hit 16" with my muzzle device.

If you're considering cutting it down for the looks, 14.5 likely won't look much different than a 16 on standard MWS handguards and it's tying you to a specific muzzle device/suppressor. My 13.5 has just a bit of exposed barrel, however, it's also SBR'd.

less for looks, more for loosing as much length as I can without going SBR and without sacrificing too much. Really setting mine up as a "do all" rifle. Its been hunting with me and with a 1-8 lpvo shorter would be nice for a bit of close up fun. Less of an issue unsuppressed but add on a 5" suppressor and I can feel the 1.5" saved.

 

[Kremvh]

Has anyone chopped a rifle-gassed 18" .308 barrel down to 16"? After selling off my 13.5" blaster SBR (RIP, miss her so), I'm putting together a new MARS-H to eat through the metric ton of .308 I have. The rifle will have a Surefire 762 Mini on it, so I want to keep it short. But a rifle gas system is appealing.

I have. Well not quite 16” but chopped mt 18” SS to 17 with a Seekins Select AGB. Dwilson did the work it shoots fantastic and is extremely soft

How does that two position gas block work out in the suppressed and unsuppressed setting? Pretty spot on?

Unfortunately no i think I’ve gotta go to something besides an H3. It’s perfect right now for 3:30 ejection pattern with the can. I opened it up till i nearly loss the detent out of the lever for the select adjustable trying to get it to cycle without the can. This is shooting AAC 175.

I always wondered about those and how they could nail the exact gas setting for all different kinds of cartridges, ammo, barrel lengths, and dwell.

Id be interested to hear if you are able to suss it out with an H1 or H2.

Hello,

I was looking to get a suppressor for my LMT MARS 7.62 gun (16" CL). I did a quick scan over this thread before posting this looking for anyone running a B&T suppressor but didn't find mention of one. Admittedly I certainly could have missed it though.

In any case, anyone running a B&T Can with success? I am intrigued by the Rotex (Print X) 7.62 Full Size and the SRBS 7.62 units that B&T offers but I'm not married to them just yet.

The voices in my head keep saying to just go with a known good unit like the Surefire 7.62RC2 (which I have already tested on this gun with no issues) but I would still love to hear any experience, good or bad, with the B&T's on this gun.

Thanks in advance

I'm stuck in-between the B&T Ti SRBS and the CAT ODB Ti for all the same reasons

I’ve found that most of us get into suppressors seeking the highest degree of suppression. The most quiet can. After some suppressor ownership we trend toward lighter and shorter with a “hearing safe” focus. 140db limit’ish. My suggestion would be to skip to the end. Light, short, 140db’ish.

I’d say that’s very true for semi autos. The best suppression generally leads to the most headaches when trying to properly gas the gun or swapping ammo.

The noise from the ejection port should be taken into account as well. You’re only going to get the decibels down so much

I have a Dominus on a 16" 308. I've been pretty happy with it for the most part. The gun gassed easily, the suppression is impressive, it has run impeccably .... but it's just gassy. No headaches, it's just gassy. For me, the options to weigh are how much increased sound are you willing to tolerate to offset the gas. If you're shooting more slow fire like a precision rifle the gas isn't a problem, it's when you're shooting a VTAC barricade and ripping off rounds quickly with the ejection port in close confines to the ground redirecting the gas back into your face.

Thanks for that assessment. I went with a Abel Thereom to hopefully reduce the gas for higher volume fire. But won't hesitate to use some of my TBACs on other barrels for the MWS.

Thanks all for the information.

I think I am going to take a pass on the B&T's and stick with the Surefire line for my rifles. I may lean on B&T for a pistol Can in the future though.

Now onto my next struggle.

Anyone running a Surefire 300SPS on an 7.62 MWS with success (16" or longer barrel)? I hear its pretty rough in terms of increased back pressure but I also have a 9" .300blk gun (and a .300 WIn Mag Bolt Gun) I am looking to supress as well. Preferably to Hollywood levels of quiet, at least for the .300blk gun...

I wont complain if I can kill two birds (or more) with one stone if possible but not if it will sacrifice reliability of my MWS. Do I have 5lbs buffer weights and 400lb buffer spring rates in my future or is it not that bad for anyone who has run such a combo on their MWS?

Would love to hear more

Just talking out ofmy semi educated ass here but suppression wise between a 300 and a 762 surefire will be insignificant if any difference at all. If recall correctlythe 300 has baffles for more back pressure so it will help makea 300blk that is minimally gassed run with subsonic just fine.

I've been suppressor hunting lately also and the mws will be it's primary host. Leaving towards the 762 mini2 myself.

 

[5RWill]

This seems slightly less weight than the H3 in it. 5.3 vs 4.9oz. H2 is 4.6oz, so it'd be between them. Think I'm going to give it a try less the H3 in the LMT is longer than a standard carbine buffer? That's what I couldn't remember.

I ran a 7.62 Mini2 on the old 13.5. Wasn't Hollywood quiet (of course), but I didn't feel the need to wear ear pro when blasting at pigs. That same can will go on the 16" .308 barrel I got from the LMT Black Friday sale.

Does anyone have a line on a LMT BCG? I understand that KAK and Toolcraft make substitutes, but I didn't get in this game to cut corners.

Well I just did exactly this. Now need to figure out which of Slash's buffers to get. With a 16" barrel, carbine gas, and a Surefire 762Mini I'd guess the XH buffer and rifle spring.

Try it with the original H3 and spring first. It works. I tried one of his buffers years ago. Turned my MWS into a single shot.
Contacted him about returning it. His attitude was basically “Tough shit”. Lesson learned.
