Windham Weaponry RMCS-4 Rifle Combo 5.56 NATO/.300 Blackout/7.62x39mm/9mm Rifle

Description

Product Overview

Windham Weaponry’s RMCS-4 multi-caliber AR platform rifle combo is designed to let you run multiple chamberings in the same AR-style setup by changing caliber-specific components. This combo is built around 16 in barrels and supports 5.56 NATO, .300 Blackout, 7.62x39mm, and 9mm by swapping barrels, magazine wells, and when necessary the bolt/bolt carrier and magazines. The barrels are made from 4150 chrome moly vanadium steel, with chrome lining for long wear and easy cleaning on applicable calibers, and black manganese phosphate barrel finishing. Receivers are CNC-machined from forged 7075 T6 aircraft aluminum with hardcoat black anodize, and the bolts are machined from Carpenter 158 steel.
