    So LMT is shipping the 10'5 inch barrel with the pistol length gas tube, 1/7 twist but what is up with that flange at the end of the barrel before the threads? My AAC 51T Blackout flash hider won't go over that..

    Never mind. It's the washer..

    What are the reliability reports with the 220gr stuff with/without a can on the 10.5" and 16" MRP barrels out there? I have a 16" I was gonna cut but would like to keep it at that (or 14.5 for the one rifle length MRP) and pick up a 10.5 for the carbines MRPs.

    Had mine cut to about 13" (see previous page for photo and explanation). No problems with the 115 gr Remington suppressed or not, but I haven't been able to get my hands on 220 gr. If you want to send some my way I'd be happy to report on it.

    I've only got 40rnds of it myself. I was overseas when all the craze kicked off and have had sooo many other projects at various stages going on that I've been sleeping on the 300blk ammo. I just put together a 16" AAC upper (Knight's 3.1) on a Seekins forged lower and have teh 16" 300blk MRP barrel to try out. I also have an AAC 18t 762SD to try with them......need the ammo. SBR is the goal though with a Noveske 8.2" bbl/Vltor MUR/7" DD lite or (Cent 7" rail) upper I need to assemble and the MRP 10.5" barrel (still to get). Have a couple 762SDN-6 cans in the works as well.
