Looks like the price went up a little? And not in stock, so backorder?
I checked with the guy I got mine from, he sold all he had. |

His price varies with the barrel length. Just last week I was quoted $300 for an 11.5" barrel with a 12 week turnaround.

I don't think ADCO's pattern is the same, but it may still meet the need. IIRC it's because of the KAC patent or something.

Dunno if I can justify that one for a bit. I tend to go through a lot of changes to a gun before I find a setup I like so I will likely wait a bit anyway. With the exception of optics, my longest standing unchanged AR is a 10.5" MRP. It was also my first SBR a half dozen years ago or so. |

Does anyone know the effective length of a rifle length MRP? Meaning: what's the equivalent handguard length of the rifle length chassis? 13" 13.5"?
And are the MRP barrels a true 16" or something weird? Reason I ask is years ago I bought a suppressor, the AAC SPR/M4, because I thought it would look great with a rifle length MRP I don't think I was wrong, but I'm wanting to use the flash hiders and suppressor on other setups, but rather than playing it safe and just going with a shorter handguard I'm looking to achieve the same aesthetic that I got with my MRP. I've had someone measure how much exposed barrel there was on the rifle length MRP (up to the shoulder) and they came up with 2.25", but now i'm curious what handguard+16" bbl will produce this same look. Seeing as how I don't have any MRPs anymore  can someone be so kind as to take some measurements for me?

https://i.imgur.com/iWGmSyw.jpg https://i.imgur.com/37DKPeo.jpg Minimum barrel length to put the shoulder before the threads flush with the end would be 13.94" (with .625" threads). The SPR-M4 goes 1.875" back over the barrel so you need a 15.81" barrel plus desired gap. If LMT barrels are 16.125", you'll be fine. You'd be good with an AEM5 too. |

I've been kicking around some ideas regarding mods and what not I'd like to do on some of my MRP uppers, in particular the LM8's. I put together a tabletop cnc mill a while back and I'm in the learning process, but today I did something pretty simple but useful (to me). One thing I don't like is the forward locations of the qd sockets, both on the LM8 and mlok uppers...it's wasted room, at least for me. So I modified a 5 slot rail for my LM8's to fit all the way forward. It's not a huge amount of extra room but I find every little bit helps on these cqb chassis. The rail section still uses one indexing hole and two bolts, so it's still secure...good enough for a light.
This little mill can do 3d milling pretty well, even with just a flat end mill. I also did an mlok finger stop out of delrin a while back and I was amazed at how well it cut compound curves. Anyway, what I really want to do is some custom G10 rail panels for my LM8's because the LMT ones leave a lot to be desired.  Attached File Attached File Attached File |

Who else is planning on starting an MWS build with the upcoming barrel and LM8MWS deals? I'm looking at the 16" CL barrel, and roughing it out a build with MARS-H lower looks possible for a little over $1700, but that's with a cheap BCG. Not sure it's a good idea to cut cost there, but going with the LMT BCG adds at least $200.
Are the LMT's LR-308 pattern? If so, I'll probably just grab a Brownells BCG for now. And, I just realized I had noted the stripped lower for $340 but not where I found it for that. Looks like that will be $400 if I can find one. Checking all the usual places. |

I just need a lower and charging handle to complete my second.
With that being said, I would really try to avoid going with a non lmt bcg. Knowing lmt's run hot, the cheapest bcg on the market is probably not the best choice. Save up a little longer, or maybe sell some old gear and build it the way it was meant to be |
