AR PISTOL 2018 UPDATED UPDATE
This video provides an update on an AR pistol build, focusing on the installation of a new 11.5-inch KeyMod upper from MAS Defense. The presenter explains the rationale behind choosing this upper, including the legal allowance for a vertical grip due to the barrel length and the desire for a lighter, slimmer profile compared to a quad rail. Key components discussed include the Surefire dual-port muzzle brake and its associated Warden blast diffuser, as well as Daniel Defense magazines.
