This is a custom AR-15 build in .300 Blackout utilizing all super premium parts and built by a retired Marine armorer for suppressed use. This DOES NOT come with the supressor. Features an Aero Precision forged alloy lower, Strike Ind premium internals and stage 2 trigger, flat wound buffer spring, Kaw Valley Precision H3 5.4 oz tungsten buffer, Strike premium Mod 2 anti rattle stock and Strike Advanced receiver extension and many small touches and tweaks too numerous to mention but everything was the best available for the intended use. 16" Right Ride charging upper with 416R SS Black Nitride Bear Claw fluted heavy barrel (1:8 twist), carbine length gas system and 11.5 MLOK and comes with 1 new MagPul GENM3 PMAG 30 round .300BO specific magazine. Other than a couple rounds for proofing it is unfired. Prefer local sale to AZ resident with drivers licence and BOS but can ship to your FFL for $50. I am pretty much selling this for what the parts cost so the price is firm but I will take .900 fine silver or American Eagles or fractional gold bullion in trade. The only gun I am interested in trading for would be an unfired NIB Stribog SP45A3 with all factory accessories and /tail hook brace.
