Hello all, I have for sale or trade a sig/ bcm gas impingement 300 blackout ar-15 pistol. This is an elite grade pistol coming to you. The upper was co-opted in a special collab with sig and alg. Upper receiver and gas tube/barrel assembly is sig. 7" chrome hammer forged barrel with 1x5 twist, alg hand guard, and comes mounted with huxwurx 7.62 5/8-24 suppressor mount flash hider. Barrel has less than 200 rounds through it. Verified concentric for suppressor use. The lower is bcm, with forward controls designs and bcm internals with forward controls designs 55 degree safety selector, percision reflex extended charging handle, Geissele maritime bolt catch/release, gieselle super SSA trigger, and super 42 42 buffer system with h2 buffer weight. Carbine length gas tube, and sb tactical sba3 pistol brace. This is an elite level 300 blackout pistol, ready for suppressed fire, and very reliable coming at an excellent price. This set up cost me an easy $2200, and I'm selling it at 1200 barely fired at all. Only reason I'm selling is I'm trying to open up a budget for an e mountain bike, and I had to make a hard decision between this or some collectors firearms I just couldn't bring myself to let go of. Would prefer to sell, but open to trades if the resale value of what's traded is above the selling value of this firearm.
