M4A1 Block II FSB Pistol Build

Description

For your consideration is my M4A1 Block II pistol build. Daniel Defense RIS II FSB free float hand guard rail, genuine Colt military 14.5 barrel from Ataka Industries, SureFire Warcomp (not P&W but can be), generic upper receiver, AO Precision surplus government contract BCG, Aero lower, BCM grip.

A couple scrapes/scratches on the underside of the rail and the buffer tube. This thing is a workhorse, and the bomb-proof lock-up of the rail provides a solid platform for IR devices to hold zero.

PayPal, Venmo, Apple Pay, cash, all that good stuff!
