Product Description
MCS AR-15 5.56 NATO LEFT-HANDED 7.5" INCH PISTOL UPPER FREEFLOAT M-LOK HANDGUARD
The MCS left-handed AR-15 upper build kit chambered in 5.56 NATO, built around a MCS 7.5-inch contour steel barrel with a manganese phosphate finish, a 1-7 twist rate, and a pistol-length gas system. The MCS left-handed slick side billet aluminum upper receiver anchors the front end with a left-hand ejection port and a clean slick side exterior that omits the forward assist and dust cover from the receiver body.
The pistol-length gas tube and micro low-profile gas block at .750 complete the gas system, and the ACE-20 Series 7-inch freefloat M-LOK handguard covers the compact forend. An A2 GI Birdcage flash hider at 1-2x28 closes out the muzzle end.
