Tough, Sleek, and ready for the AT3 SPEAR M-LOK Handguard
Machined from billet aluminum, this unique slick-side upper receiver has no forward assist, includes a dust cover, and matches perfectly with AT3’s SPEAR handguards with anti-rotation features. This upper also features more material to surround your barrel extension than typical forged receivers, making it more ideal for precision. This lower matches up with mil-spec lower receivers for a secure, reliable fit.
The AT3 Slick Side Upper Receiver also comes in a wide variety of colors, ranging from classic black, Magpul-matching Flat Dark Earth, vivid Pink, USMC Red, and even new metallic shades like Tungsten, Titanium, and Burnt Bronze. Flat black uppers have classic hard-coat anodizing, while the other colors receive a durable Cerakote finish.
