Built around a Daniel Defense mk18 barrel, 10.3" CHF CL, pinned gas block and gas tube with a DD FH. I've only put 90 rounds through it, No BS, 90 rounds. Upper and lower receivers are 7075 T-6 billet aluminum from Next Generation Arms and features a tension screw to keep everything tight and rattle free. CMMG LPK. Ambi safety. 7075 billet qd endplate. Upper receiver is a slick side receiver hence it has no forward assist but does have a shell deflector. Rail is a 10" m-lok rail from Guntec. Ok, ok, not the best rail I know but its actually pretty damned solid. Trigger is an ALG PNT ACT mil-spec unit. Best mil-spec trigger out there, period. Brace is SB SBA3, tube, action spring and H1 buffer. Guys, this is one sweet brace. I love this thing. Mil-spec charging handle. No bcg, but I will include the magpul AFG and the magpul MBUS. One caveat, the front sight will NOT lock down. Look, I know the "100 rounds" and "300 rounds" are calling cards of the bullshit artist but no BS, I built this, fired 3 30 rd mags through it and haven't fired it since. Those 90 rounds were flawless. It functions 100% and it shoots great. It's my first pistol and I was surprised how "soft" it shoots. That barrel is perfectly gassed. I was firing 55gr 5.56 mil-spec ammo. Other than the Guntec rail this pistol has all quality parts in it. I just am on a revolver quest and to get what I want I'm gonna need more money. Looking for $600+ any fees Also willing to entertain trades for S&W 686 4" or 627 4",5" Would also be interested in a 29 or 629 with 4" Barrel lengths negotiable depending on specific model and condition. I can also offer cash on my end for a nice revolver. I know someone here has too many revolvers and wants to part with one, like me and ARs, I just am getting too many.
