LMT .308 MWS

Re: LMT .308 MWS

So I bought a UBR stock but I'm having trouble getting the old buffer tube off. It looks like it's staked at least 4 times. Any advice before I do something I regret?
 
Re: LMT .308 MWS

Wow, what a nice rifle.

My country does not allow any real steel gun so i have to deal with airsoft

You can drill the stakes out or you can hacksaw them out. I would not just use brute force to unscrew it you may dammage something very expensive. Or you could just get a Magpul ACS stock.

But if you have to have a UBR Ill buy the OEM buffer tube off you. Serious about that.

Just to make sure you know the MWS buffer tube is longer than a carbine tube (what the UBR uses).

If you look back a few pages I went through the same thing. All you need is a big castle nut wrench that has 3 tips. It twists right off with the bigger wrench. I posted a pic and name on an earlier post.

Ive done the same thing. I use the RRA castle nut wrench which engages in 3 places. You can twist the nut past the staking. Ive never had to drill one out.


I was just mentioning the different buffer tube sizes because he would need a new buffer to work with the UBR. I think people are using the "Slash" buffer which is a shortened carbine buffer.
 
Re: LMT .308 MWS

The UBR requires a different spring and buffer than OEM. And everything on the rifle is tight! Pins, tubes, etc. I have a tendency to break things so I was a little frustrated when working on my LMT, it all worked out though.the pins for the trigger guard were the worst.
 
Re: LMT .308 MWS

I installed a UBR on mine. As stated, the castle nut will twist off(most likely) with a good wrench. I ordered a XH CAR-10 buffer and modified spring, and it all works great. I got the XH buffer because I intend to shoot this gun suppressed in the future, but it works fine unsuppressed, as well.
 
Re: LMT .308 MWS

Thanks for all the advice, gents. I picked up a buffer and spring from heavybuffers and also a 3 point wrench from RRA. Now the waiting game for that stuff.

I'm keeping the old SOPMOD stock for my first AR15 build I'm working on.
 
Re: LMT .308 MWS

OK so my rifle is back from LMT for the failure to eject. As promised I said I would explain what was wrong with the gun upon its return.

I was told by LMT that my 16" chrome barrel had a gas hole that was oversize and out of spec. The larger hole caused the BC to move rearward rapidly and faster than normal. The over-speed BC caused the brass to ricochet around in the breach area instead of ejecting which ended in a stove pipe. This problem was a random issue that seemed to happen about 1-3 times per 100 rounds. LMT replaced my barrel under warranty.
 
Re: LMT .308 MWS

Great shooting KJ...that's what the hell a Rock 5R should do on paper. That's the type of accuracy that elevates these amazing rifles in a league onto themselves in s/a world.
 
Re: LMT .308 MWS

Well, looks like I'm going to have to drill out the staking on the castle nut that is retaining the buffer tube. I bought the 3 point wrench but this sucker isn't moving anywhere. Not sure whether to be pissed with LMT over this or if I should admire them for putting so much effort into making the whole thing bullet proof.

I'll put her under the knife tomorrow.

What kind of barrel?. Is that the SS or CL?

Chrome, the SS has the gas block sticking out about 1.5 inches.

Re: LMT .308 MWS

Finally got the buffer tube off and the UBR stock on. Had to leave some less than glamorous indentations where the original staking once was but there was no way to get that thing off without drilling a bit - and even then using the wrench was still a pain.

Anyways, really happy with the feel of the stock and I'm anxious to see how the Slash's buffer and spring perform. Only other thing I was not happy about was the amount of play the UBR buffer tube had with regards to the indentation at the base of where the buffer tube screws on. I stuffed it with a little paper wad and then screwed the tube on along with the end screw and now it's extremely snug without any play.
 
Re: LMT .308 MWS

Shot the SS barrel today at 350yds. Winds were gusting strong at aprox 20mph west to east across my target. With an acog 3.5x horseshoe-dot I was easily able to shoot an orange size group with untested handloads using Kentucky windage. I just threw the loads together the night before leaving to the desert. The SS barrel rocks. If I had a big powered scope Im sure I could shoot small groups.
 
Re: LMT .308 MWS

I shot mine for the first time Saturday. I was impressed. I was sighting in so I didn't get a chance to do any long range stuff but everything worked nice. 2.5" groups at 100 yards. I know the rifle can do better once I get used to it and the IOR scope.

On the 18" and longer barrels, for sure, but do the 16" SS barrels use the longer gas system as well?

Re: LMT .308 MWS

I have the 16" Chrome lined. The next barrel I get for this rifle will be in 6.5 Creedmoor. I might not be able to wait though...I'm wondering if I can have a Bartlein barrel made and then have someone do the conversion...say 24'bbl...would be nice for sure.

Re: LMT .308 MWS

Got a chance to take my MWS to the range today to work on load development. It was 26 degrees, sunny, and almost no wind. 175 SMK's with 44.0 grains of Varget got me an average velocity of 2570. Not too bad for an 18" barrel. I will probably tweak the load a few grains to see if I can get better accuracy, but so far I am pretty impressed. Sorry for cell phone pics.

Re: LMT .308 MWS

Did you use a break in procedure with the SS barrel?

Any issues with the metal LMT mags? Mine won't lock in, PMag will lock and engage the bolt hold open.

I didn't do any break in on my barrel. The mags that come with the LMT are SR-25 mags made by Knights Armament. They retail for over $100 bucks. That said, I have had no problems with any Pmags I've ran with it (6 total) so I sold the KAC mag without ever taking it out of the plastic.

I bought 6 pmags and only use the KAC mag. I did not break-in my barrel either. Shoots awesome. I would love to install a barrel brake but do not want the massive carbon build up that comes with it. I tried 2 breaks so far and both made tons of carbon on the crown. (JP/PWS)

If you get a chance can you chrono some 147/150/ 155smk's? My gun shoots 155's and 147's amazing.

Thanks, I was going to go with Pmags because of cost also but it bugs me the KAC mag won't fit. Will call LMT Monday.
I will look at it closer today.
Need to get a scope mounted and go to the range.

I've got some Federal American Eagle 150 grain ammo I can run through the chrono next time I'm out, but I don't have any 147 grain or 155 SMK's. I do have a few 155 Scenars that I'll run as well if that helps.

Re: LMT .308 MWS

The LM308MWS got a nice write up in the recent Guns & Ammo, Book of the AR-15. The article is titled: Crowned: L129A1 by Eric R. Poole. My favorite quote, "And to sweeten the experience, each of us was given the opportunity to extensively test fire what certainly may become the most sought-after production 7.62 Stoner rifle in existence."

I tried to pull it up on www.gunsandammo.com tonight, but the site was down for maintenance.
 
Re: LMT .308 MWS

I have already made the conclusion that my MWS is one of the finest rifles I have ever owned.

I am a LMT fan, my entire collection is LMT, sold all that I owned before to purchase this line of rifles and have never looked back. Never had a FTF, FTE, nothing, with any of them.

The MWS is an outstanding shooter, accurate and while I do not have a lot of rounds done the barrel, I only see the rifle getting better.

I am running a TA11 ACOG now but will be switching to a NF as soon as I get a break from work and spend time installing and setting up. The other items on the rifle are: LT/Harris bipod, ERGO ladder rail covers, PWS FSC30 muzzle device, Magpul enhanced trigger guard, lubricated with Slip 2000 products.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: socket70</div><div class="ubbcode-body">MidwestPX - does the fact that the bottom plate is pinned mean it can't be removed for cleaning? </div></div>

I have converted my own to 11 rounds. By cutting the magazine down and gluing (JB Weld) the bottom on, knowing that it will not be removable for cleaning. The issue I have with the pinning is the web that the pin goes through is thin in height. The JB weld is very strong and will not fail. I have loaded my converted magazine dropped from the mag well full, on concrete, thrown up in the air loaded and unloaded, many times, no issues.

Applying the JBWeld in the right way is the key to making the magazine hold together. Clamped and set up for 48 hours before releasing the clamp.

I have four 5.56 Magpuls that I cut from 30 to 20 rounds way before Magpul came out with the 20 rounders and they have seen 1000's of rounds without an issue. All modified as I described.

Look at the shim combination close and clock it such that the top flat is at 11 o'clock real hand tight. I then took the correct open end wrench, placed it on the PWS and with a brass hammer, tapped the wrench until the flat with the PWS symbol is right at 12 o'clock.

Why a hammer and tap? You can control the tightening of the PWS, tap look, tap look, I did not want to over run the 12 o'clock and have to loosen. The pitch of the thread is 24TPI, the PWS moves .041" per revolution, using the very thin shims will be needed. You will have to play around with the shim combination.

If you follow this, the installation will be easy.

Re: LMT .308 MWS

Judge,

I had the shop where I purchased the MWS loosen the A2 before I left, as I had a Smith Vortex to install when I got home. The SV was easy to install, no indexing and tightens while being shot.

If you don't have a gun vise, I would suggest you can try the same technique I described above to install, the A2 flash hider uses a crush washer, so it may be a little tougher to loosen. Just be careful, let me know how it turns out.
