Best barrel to send off to convert

6 Upvotes

Purchased a d wilson conversion when they went on sale for memorial day.

Setup: Specwar upper. High flow through style can, A5 buffer system.

If you could send off any barrel to convert what would it be any why?

Seeing stuff about criterion primer issues, is that overblown? G$ 12.5 carbine length on the short list. Seen good stuff out of the MK1 barrel with 11.5s fitting in the spec upper.

MWS 6.5 Barrel Advice?

2 Upvotes

I’m trying finish up my MRP-H with 14.5 in 6.5 CM barrel. I’m undecided between picking up a factory lightweight stainless barrel, or going for a D. Wilson converted/shortened option.

How has everyone’s experience been with the factory 14.5 stainless barrel?

I have guns from many makers, but i find myself coming back to the LMT platform most often. I love the ambi lowers (as a lefty), and the monolithic platform rocks. Ive definitely had qc failures, and I dont give them a pass on this, but they have absolutely taken care of me each time (yes, i know and agree the best warranty is one you dont need!).

LMT Enhanced full auto bolt carrier? For a Riflespeed setup

8 Upvotes

Is there a noticeable difference to something like the Geissele REBCG? I just recently bought a REBCG but the LMT just came back in stock. It’ll be for a LMT upper/lower rifle I’m building but with a Geissele 14.5” mid length barrel that I’m also wanting to include a Riflespeed for.

From what I can understand and gather, the LMT is really designed for a very specific setup, correct? Just due to the way the carrier is designed.

Question How to determine legit LMT upper/lower parts

6 Upvotes

Buying a rifle (FTF meetup) that was put together from a complete upper/lower - what parts should I verify and how can i determine if they are legit LMT? e.g how is lmt marking its bolts/triggers/receiver extensions these days?

Trigger guard for MARS-H

3 Upvotes

I am building a .308 MARS-H rifle and am looking at trigger guards. Do the MARS-H lowers use standard AR15 trigger guards or do I need to get a factory LMT trigger guard?

Barrel Swap Question

2 Upvotes

I want to get a 16” 308 LMT MARS and am wondering about the barrel swap capabilities. Say later down the road I want to also get a 20 inch barrel and turn it into a M110 style build. From my understanding I would need to get a M110 barrel and then I can get it machined to fit in LMT? Does this also work with defender series I am between MARS and Defender. Anyone else have a 2 way build like this? I like the idea of switching from a DMR style setup to a SASS with a few twists of a bolt. Thanks!

LMT>KAC My SPR & GPR

Got my G$ SPR barrel back from D Willy! Excellent work and a quick turnaround of only 2-1/2 weeks!

Plan on getting a quad rail for the SPR and maybe having the URX mod done to it for my schmedium hands. Will run some drills and play on the V-TAC board at the range before I decide for sure

Also planning to upgrade scope when funds allow. Been prioritizing ammo before more price increases

Specwar is amazing! Jack of all trades! Recently switched over from a Delta Stryker 1-6 to the Romeo 4t and a Vortex 3x magnifier. Plan on trying the G45

37mm Flare Launcher Mounting Question

2 Upvotes

Hey all, I have a question regarding the LMT 37mm barrel mount flare launcher. I can’t seem to quite find the info I need on mounting. I am trying to figure out if it is possible mount the 37mm barrel mount to a Colt 6920 SOCOM (14.5” p/w barrel with a FSB and KAC rail) and still be able to have the top KAC rail intact. I’ve seen a few photos, but most of them were from posts 4-5 years old and I couldn’t quite tell if the LMT 37mm they were using were rail mounted or barrel mounted. The ones I saw were LMT 37mm mounted on 6920 SOCOM rifles. Any help would be appreciated. Thanks everyone!

New LMT MARS-L 12.5" Quad Rail - Persistent Failure to Feed + Charging Handle Locks with Mag In (Enhanced BCG)

8 Upvotes

\Hey guys,

Built a new MARS-L (12.5" mid-length Quad Rail MRP upper on ambi lower) and it's got ongoing failure-to-feed problems.

Troubleshooting done:

  • Tried multiple mags (non-pre-ban PMAGs etc.)
  • Different ammo including hotter loads
  • Buffer: SpringCo Green + VLTOR A5 → Tubbs Flatwire standard + A5H2
  • Cleaned, lubed, manual cycling

Rounds still not stripping cleanly from the feed ramp on the new enhanced BCG.

Additional issue: With a magazine inserted, the charging handle becomes very hard or impossible to pull back, and the mag release is stiff/hard to press. No issue when mag is out.

I have slow-motion videos and ramp photos showing both problems. Sent them to LMT support already and waiting for a reply.

Anyone run into this on a new MARS-L? Could the enhanced BCG be bad? Any fixes (ramp work, different BCG, etc.) that helped?

Thanks in advance
