BRT 12.5-inch Suppressed Build on an Icon Defense Billet Upper

A suppressed 12.5-inch build pairing a BRT hammer-forged, chrome-lined barrel with BRT's EXC gas length and a HUXWRX Flow 556k. It sits on an Icon Defense flared billet upper under an 11.8-inch Icon DriveLock rail, with an Aero M4E1 lower for now (a PWS lower is planned). Geissele supplies the reliability-enhanced carrier and SSA-E trigger, with a KAK K-Spec A5 buffer system, a Magpul DT-PR stock and an EOTech EXPS2-0 green.
