Product Description
MCS AR-45 5" INCH 45ACP PISTOL UPPER 1:16 FREEFLOAT M-LOK HANDGUARD
The MCS 5-inch .45 ACP AR-45 Upper Build built around a slim-profile barrel and a pistol-caliber AR-15 billet upper receiver. It pairs a 4-inch ultra-lightweight minimalist handguard with a MCS Micro Flash Can at the muzzle, giving this build a compact, front-heavy-free profile. The whole system runs on direct blowback, so there's no gas block or gas tube anywhere in the build.
