Even with a slash xh buffer, flatwire spring and surefire socom I still had some failures and ejector swipe. Mine is an older one with the single ejector, single spring extractor though and adding a JP extractor and springs did help.

I am not sure if they changed any of the port sizes but they don't seem incredibly different. I would recommend at least picking up a current gen Bolt, I was having some issues with the gen 1 bolt years ago while suppressed. I would also experiment with other springs, not sure where i read it, but i heard flatwire springs were not the best option for the MWS. Could be totally wrong on that, I will do some research
Guys on my MWS I had Mark Chanlynn make up a 6 Creedmoor barrel for me. I used a standard gas block which Mark had to straighten the gas tube. It feeds and shoots lights out. We robbed the adapter off the 308 barrel that came with it originally since I also have a 6.5 Creedmoor barrel for it. Don’t think you are only limited to LMT offerings.
Good to know.
What is an optimal length for a 6.5 Creedmoor for distances over 600 yards?
Personally I like longer barrels, it gives me a little more fps with out pushing the pressure. In 6.5 to only go out to 600 yards pretty much any length will work. My 6.5 is 20” but my 6mm is 26”. With 108BT I can push 3100fps with no pressure signs. Plus it shoots nice little groups.
Good luck with your barrel choice.

Hey, guys...dumb question.
Is the only thing you have to do to use 6.5 creedmoor in your LMT MWS is buy the barrel? Or do you have to get a different BCG?

All you need is the barrel. I shoot 308 and 6.5 with the same bcg. Some guys like to keep a bolt with the barrel.
Yep. I have dedicated BCGs for each but you don't have to. It's a pricey route but 1 is none and 2 is one-3 is even more fun etc.
Couple more questions:
What would be the downside of a 27" barrel?
And....I can see the "bolt with the barrel" idea, but would you really need a whole other BCG?

Other than being unwieldy as hell?
Not sure I have seen a 27" on an AR.... I think if you wanted to do it, the bolt would be sufficient.
I think bolt is key-I just happen to have 3 uppers and 3 BCGs. If I ever switch barrels I'd likely get a new bolt and keep carrier in upper.
I switched from the gen 1 single ejector to gen II dual ejector bolt and it made a big difference in what brass looked like from my 16"CL.
I still need to pick up my mars-h lower and form 1 it. I'm torn between cutting my 16" CL (which was dimpled by Marvin) to 13.5 and maybe buying a 16"as or just buying a 13.5 ss.
What kind of velocity are folks getting from the 13.5? Playing with ballistics it looks like with 150yd zero and a 175smk/178amax going 2350-2375 it would line up almost perfectly with the cmr762 in my mk6(using yards instead of meters.)
Eta: I have a 24" 6.5 barrel for mine. I didn't necessarily want 24 but it was available. It's obnoxiously long with a can. If it didn't shoot so well I probably would have cut it to 20.

Rarely go on sale. Try giving LMT a call and asking them for a deal. You never know.
I just picked up a burnt bronze MWS in 308 and mounted a ZCO 4-20 on it. Looks great. I think this optic is a really good fit for this platform. I have a DMR stock and a 20" 6.5 creed barrel on the way. Hopefully I can make it to the range this weekend. Will post a range report.
Looking forward to hearing how she does with that 20" 6.5 Creedmoor barrel! Please post up pics of your best groups. I put a Geissele trigger group, SSA-E, in mine.
Last year they had a great 12 days of christmas sale. Barrels were ridiculously cheap. Kicking myself for not buying.
but I don't know about anything right now. They do have flash sales from time to time.
Just purchased the Texas Predator edition in 6.5 CM. Going to be mounting a Minox ZP5 on it next week and will update you guys when I finally get it out on the range.
I also want to get a 16" .308 barrel for it and their torque wrench and was hoping they would be part of the Labor Day sale....alas, only 5.56 barrels.

LGS had this tucked away in a corner, said they've had it for over a year and offered me a great deal on it, I had an extra scope laying around which made the deal even easier to do. Very impressed with it so far, ready to go shoot it.
I did a forum search and cant seem to find an answer to this:
Does anyone know the measurement from the center line of the bore to the top of the flat top receiver? For the .308 barrel if it matters. I'm trying to figure out what my scope height is for a ballistic calculator.

Open the ejection port cover use the gas holes on the bolt carrier as measurement reference point for the center of the carrier. Then measure to middle of scope. The bolt travels in the carrier along with firing pin which effectively is the center of the barrel. This will get you to within 1/16 of inch. This should allow your app to be close enough for good solid data to start with before getting corrected dope on the range.
I have an older LMT MWS that throws the brass directly into the far rear corner of the ejection port and base of the deflector upon ejection.
This has worn the finish off in those areas and created somewhat of an eyesore.
Maybe most would not mind it but I haven't seen any other LMT that does this.
Is there anything I can do to get the ejector to throw the cases out before they strike the far rearward portion of the ejection port ?
Do I need a heavier buffer spring or what ?
I would put some touch-up Aluminum Black on the area but need to try to get it stopped first.

My ZCO 4-20 has 25mils of usable adjustment with a 0moa base. I'll only ever use half that so no need for a 20moa base.
Gents, finally going to take the leap to 6.5 CM. I swapped out my factory H3 buffer for one of Clint's Extra Heavy (XH) buffer. I'm assuming I can keep the XH buffer in the the tube while running the 20" 6.5 CM barrel (suppressed) with no issues. Wanted to see if anyone else is running this setup and what are your results? Thanks.

I am running Clints buffer/spring Combo in both my 13.5 308 and 20 inch 6.5CM. Works great, both suppressed and unsurpressed
I'd send it back or give them a call. Mine, regardless of what ammo I use and I've used wolf in the cl barrel, throws them clear across past the guy next me at 3ish o'clock. I mean it's AK like
how good a deal? what's he charge for uppers as I've barrel I want to mount and not swap?
I'm not sure how much he stocks so it may be special order but he has the best deals I've seen on LMT stuff anywhere. 10-15% maybe.
6.5 CM barrel inbound. Last shot of the South American in a 7.62 configuration for the time being. Shown with new optic (moved the MK5HD over to the SR25). Charlie Mike
20" SS 6.5CM barrel arrived and installed over the weekend. Expended five rounds to sight in before moving on to shoot two separate groups to assess accuracy. Just grabbed whatever COTS ammo was behind the counter at Walmart and headed out, but it seems to like both. First group was Federal 140gr SP. Second group was Federal 130gr Berger OTM. All suppressed. Shooting position was seated shooting off the bipod with rear bean bag support. Roughly an MOA shift between the two. Looking forward to exploring other loads. I'm still running the stock trigger, just polished a bit to eliminate the grittiness. Will be installing a DMR trigger when I get around to it. I can't say I'm disappointed with the results.

That's excellent accuracy, shooting with a bipod and bean bag for an AR.
Redundancy. One of these is going away.
I'll take that lunchbox receiver set off your hands!!!
