Custombilt Firearms MFG MMPB-556 5.56 NATO Pistol - 10.5"

The MMPB pistol combines modern features with classic lines. The MMRB-556 contains the same components as the MMR-556, but incorporates an F marked front sight block, and Magpul Industries MLOK SL handguard. This combination results in a slightly more cost effective pistol that is still suited for extremely hard use. 

At the heart of their pistols, Custombilt uses their M16 cut nitride bolt carrier group, matched with a fully nitrided Ballistic Advantage 10.5” carbine-length barrel. Their carbine-length gas system provides an extremely soft and controllable recoil impulse. 

Custombilt MPP-GI trigger has micro polished contact surfaces, and a fitted disconnector. This combination gives you the 5lb weight of a typical duty trigger, and removes all of the gritty drag while breaking the shot. Their fitted disconnector gives a positive, short reset that is hard to miss!
