Replaced the original buffer in my LMT 6.5 Long Range 24" barrel (308 with the 20" barrel) with the XH Carbine Buffer from www.heavybuffers.com.

View attachment 7218252
The additional weight (8.5 oz. total) of the buffer brings the felt recoil down without sacrificing reliability. The XH Carbine Buffer works perfectly when shooting 308/7.62x51 NATO or 6.5 Creedmoor.

Clint really knows his stuff. I had a couple questions and he responded with clear and concise answers in less than 2 hours. He even responded to an email at 2:58 AM! Order was shipped very quickly.

who else is using this setup? I tried my MWS suppressed (SAS Arbiter TI) and it launched brass into orbit and the the 5 shot group I tried doubled in size. I’m going to try again next time I shoot To make sure it wasn’t me. The first group I shot with the A419 Break was great, but with the can it opened up big time.

That's a gorgeous rig. Very well done. Updated mine as well.

The XH buffer works as advertised. In an attempt to reign in the over-gassed MWS I tried a few spring + buffer combos as well as an adjustable gas key installed on the carrier, which initially yielded positive results, but ultimately proved inconsistent when shooting a variety of loads, with and without a can. Before reverting to more extreme measures (e.g. AGB), I contacted Clint at heavybuffers.com and was sold on the idea of employing an XH buffer, which I run with a factory spring residing in the extension tube. Not only did it mitigate the residual effects of excessive blowback by slowing the weighty reciprocating mass of the bolt group significantly, but reliable function of the system finally stabilized, resulting in flawless performance running a variety of loads both suppressed and unsuppressed. For me, hands down this is the single best investment I've made in this system in the five years I've owned it. YMMV

That reminds me, I bought five magazines during the Black Friday sale and they don't work at all. Double feeding, won't drop free. Haven't emailed yet but I should.

edit: these were "D&H TACTICAL 20RD .308"

Update on these. I put my .308 barrel back on and tried them. They worked perfectly (well, feeding was OK, but they still don’t drop free). I guess I’ll just use PMAGs for 6.5 CM.

Been toying with dumping my scar 17 in favor of this rifle, anyone done the same?

Yeah... I am in the same boat, I have an 13.5 MWS, with spare 6.5 upper that will be built into a second MWS eventually. I just picked up an SR25 ACC, and I have had my Scar for about a year or so now.

I think that the scar is very reliable and light weight weapon, and part of me does want to keep it, but I just feel if you take away the weight aspect of the Scar, the MWS and SR25 are just better weapons. the shoot smoother, are more suppressor and elector optic friendly.

I think that something that is missed about the scar and MWS,

MWS 6.5, 10.3 LB, OAL 38 inches
MK20 6.5, 11.2 LB, OAL 40Inches

MWS in its lightest configuration 8.5lb,
MK17 8lb

While configured as a carbine, the Mk17 is indeed a half pound lighter, but if configure for longer ranges, its almost a full lb heavier. and two inches longer.

I will eventually dump mine and put that money into new optics

So this is pretty much exactly why I've been staring at my scar wondering what I'm going to do with it.

While I enjoy it, I'm happy with 5.56 for my 400-500 yard distances and when I start to stretch past that i can't help but wonder if those funds wouldn't be better used behind a gas setup like the LMT.

Obviously only you can decide, but I do find your comment regarding "wondering what I'm going to do with it" somewhat funny because if I shoot the SR25, and Scar back to back, The immediate impression I get is ewww, what is wrong with you. you weight the same as my SR25, have a muzzle break, and somehow have a noticeably harsher recoil impulse.

When comparing it to my MWS, its a little lighter, but feels, for lack of better words, cheap. and this even after all the typical scar upgrades.

I never really cared for the SCAR. It's a nice weapon, but just not for me. I'll put a lot of money toward my MWS and SR25 though. Between the LMT and KAC, it's really hard to pick a favorite because they both are great weapons and both have their strengths and weaknesses. If I had to choose between the MWS and SR25 it would be a hard choice, but ultimately I'd opt for the latter.

Well, what I've decided to do for now is focus on glass. The role will be the same, so choosing my glass while i bide my time is the best option at the moment.

The LMT is at the top of the list for SCAR replacements and once tax returns roll in, I'll have my mind made up I think.

Is the rifling in the SS barrel cut or button? I know Obermeyer and Kreiger, who seem to be the biggest proponents of 5R rifling, only do cut rifling, not button. Also, I read that the Chrome plated is polygonal rifled? The MWS upper I have has the SS barrel, so it has the 5R version.

My SS Barrel says "MP 7.62 NATO 1/11.25 SS"

Realistically, either barrel should be sub-MOA with decent ammo, and sub 0.5 MOA with good ammo. Is 1:10 better at stabilizing heavier projectiles than the 1:11.25? I've read that 1:11.25 is better with M80 ball (~150gr) than the 1:10, while both are good with the MR118 (~173gr) and 1:10 is significantly better with sub-sonics

If sub-half-MOA ARs were as common as people claim, they would dominate PRS. As it is I don’t see a lot of 6x5 targets for these things.

There was a thread in this forum about Savage MSRs not that long ago and the term "1/2 moa all day" was thrown around quite liberally. Then near the end a dude posted a 3 (I think) shot group at ~1/3 moa lol. It was a nice target. I'm a decent shooter and shoot KAC and LMT ss barrels all the time, bipod and rear bag, concrete bench, many perfect non windy days etc, and I'm still 1moa-a little better occasionally and a little worse usually.

I shoot with a lot of good shooters with high end equipment and I see the same thing for the most part. You get into bolt actions and they're consistently below 1" but they still have to work hard to get it.

I was shooting today and with ammo it likes (Hornady 155 AMAX over Varget), it was an honest 1" gun, with other ammo I took for comparison, it was 1-1/2" to 2"

I can live with 1-1/2" out of a semiauto battle rifle all day long. If I'm doing my math right, that's a center of chest hit to 600 everytime.

Hello all. I'm a new LMT 308 owner. I joined this forum specifically because it's just about the Only place I've found where people are keeping alive a discussion about this gun. Almost anywhere else I looked, I couldn't find any current topics about the LMT MWS 308. All my googling just turned up years old threads.

I'm glad to have joined the club. The club of LMT owners, that is. This is actually my first 308. I was kind of surprised because I expect a 308 to be heavier than AR-15s, and everybody always says the LMTs are heavier compared to other AR-10s, but this gun really doesn't feel that heavy in my hands. Of course, it could be due to the mlok rail and lightweight CL 16" barrel.

I've only shot it once, and it was at >25yrds. I was waiting for my Nightforce NXS to come. Now that I have it, I need to get out to the 100yrd range. Unfortunately there's no range anywhere near me with longer than a hundred.

I'm sure I'll be asking you guys questions and opinions in the future. I'm glad to have found a place where people still talk about these guns. It's weird to me that it was difficult to find anything recent.
One thing I'm wondering; what's a good "battle zero" with 308s. I used to do the 50/200 with AR-15s, I kind of go for the 36yrd lately. But I've never known anything about what's good for a gun like this one. Or do people just zero at 100?

Anyway, here's a quick picture to say hello.

Nice setup. I do 100yd zero as well. My club has steel at 200-400 so that works for me.

great looking stick, welcome.
m4carbine.net has 300 pages of lmt mws talk:) you got a great brake on her.
100yd zero is fine

What kind of accuracy should I be getting or expect with a 16” 308?

Your standard 16CL will often shoot MOA, the SS barrels will often shoot .5 MOA. Every barrel is different as is every shooter. But other barrels you can bump .5 moa to both of those numbers depending on the luck of the draw.

My 16CL LW was a 1.5 MOA gun. A friend gave me his spare (only bought to shoot 6.5) and his standard CL shoots MOA. I bought a 20 inch SS and it shoots sub moa easy and often. Just to give some perspective and variance.

I think the LW barrels are just as good, I think luck of the draw.
