MCS AR-15 5.56 NATO 7.5-INCH PISTOL UPPER 1:7 FREEFLOAT M-LOK HANDGUARD
The MCS 7.5" Pistol Upper Build Kit delivers precision-grade materials and compact dimensions for versatile AR-15 pistol configurations.

The pistol-length gas system with micro low-profile gas block ensures reliable cycling in an ultra-compact package. A free float M-LOK handguard constructed from 6061-T6 aluminum provides lightweight accessory mounting, while the billet panhead upper receiver features an anodized finish for corrosion resistance and distinctive aesthetics. The kit includes a 1/2x28 TPI GI A2 flash hider and maintains full compatibility with standard AR-15 components. Ideal for builders seeking premium materials at a value price, this upper kit combines 416R stainless steel precision with modular design.
