re: Official AR-15 thread

Alright, heres a couple of teasers from the work i'm having done to one of my MRPs.

@d.wilson_mfg on IG has had my upper, thunder chicken and a brand new Rosco Mfg 300 Blackout barrel for the last week.

It started as a standard 10.5” 300blk barrel that I had him chop to "flush fit" the suppressor just off the rail, and recessing the wrench flats just under the handguard.

In addition, some of you may or may not be familiar with the LMT MRP, but it is a Monolithic Rail Platform that uses 2 retaining bolts in order to secure the barrel. this means that with the removal of the 2 bolts I can change barrels, calibers etc in about 30 seconds. in order to make a normal barrel work with this system, d.wilson fits a collar over the barrel, up against the original barrel extension and then machines a relief cut at the bottom of the collar which allows one of the retaining bolts to pass through.

Once I get it back I will take more detailed pics to show what im talking about here
