AR 15 Pistol Upper

AR 15 Pistol Upper

An AR 15 Pistol is fun on the range and highly effective for personal protection. After all, there's a reason why SWAT teams will rely on the 5.56 NATO cartridge for breaching and operations. And building an AR pistol is just as easy as building a rifle: They use virtually all the same components -- upper receiver, lower receiver, parts kit, buffer tube, recoil spring, buffer, and bolt carrier -- with the only primary difference in appearance and function being the barrel and gas system, and the legal requirement that you do not affix a buttstock to your buffer assembly.
