AR-15 Pistol Upper Barreled Assembly 10.5″ Options

New Mexico Weapons high suggests the use of 10.5″ upper assemblies for AR-15 Pistol builds.  The 10.5″ barrel length allows the length needed for a carbine length gas system vs. a pistol length gas system.  This results in half the pressure forcing the bolt back greatly reducing felt recoil.

The two other benefits are higher velocity which means greater accuracy.  If you are using iron sights, the longer upper allows for a longer sight radius vs. a shorter upper.

The shorter the barrel, the less powder gets burned in the barrel which equates to a larger fireball.
