Brownells 75th Anniversary - A Shooting Heritage

Completely Assembled, Ready To Install On Your Choice Of Lower

Complete, fully assembled M4-type upper receiver is ready to install on your lower of choice. Add a rear sight or scope, and you’re ready to go shooting. Perfect for converting a rifle to a carbine, or build a completely new gun customized to your exact requirements. Manufactured in the U.S. from top-quality materials to original Colt specs; each part is gauge-checked during assembly for correct tolerances under MIL-STD 105D. Forged from 7075 T6 aluminum alloy, then hardcoat anodized for added strength and wear resistance. Includes a standard military contour, 16" barrel with six-groove, 1-9" twist rifling, plus an A2 gas block/front sight with bayonet lug and 1¼" wide sling loop. A2-style flash suppressor has five ports on top and a solid bottom to prevent dust signature when shooting prone. Flattop accepts a detachable carry handle, scope, or red dot sight; laser-etched white index numbers aid in temporary removal and replacement of sight without loss of zero. M4 handguard is molded from tough, high-impact polymer that resists moisture, temperature extremes, and chemicals.
