Description

If you're looking for a pistol-sized AR-15 that shoots the .300 AAC blackout caliber, look no further.  This is a great build kit for just that purpose.  For this particular kit, we decided on a pistol gas system and barrel to make better use of the ballistics associated with supersonic and subsonic .300 BLK rounds. Additionally, if you decide to get a suppressor later (through legal means, of course), the 10.5" length of this kit's barrel will allow either type of .300 BLK you feed it to reach optimal velocity and stability. This kit features a 10.5" stainless steel barrel as previously mentioned.  You also get a 10" free float M-Lok handguard for mounting accessories and the Shockwave blade pistol stock kit to wrap this build kit up into a sweet little package.
