Lower Receiver and Trigger

The Delta-M4 No Logo forged 7075-T6 aluminum lower receiver carries a Type III hardcoat anodized black finish with a Mil-Spec AR-15 pattern, a low shelf trigger pocket with M16 cut, and Safe, Semi, and Full Auto selector markings. The receiver is made in the USA with minimal exterior markings and no logo beneath the trigger pocket, a clean exterior profile for builders who prefer a low-profile or unmarked lower receiver aesthetic. Manufacturer, origin, and serial number markings are present on the side of the receiver as required. The complete Mil-Spec AR-15 lower parts kit covers the full internal lower component group with a Mil-Spec curved trigger at its center and a Mil-Spec A2 grip in black covering the grip interface.

Buffer System and Brace

The Mil-Spec heavy-duty 6-position carbine buffer tube, standard AR-15 carbine buffer at 3 oz., and standard AR-15 carbine recoil spring made in the USA form the complete buffer system at the rear of the lower. The US Tactical AR-15 and M16 Mil-Spec receiver end plate and Mil-Spec AR-15 carbine castle nut lock the buffer tube down cleanly at the rear of the lower receiver. The SB Tactical SBA3 adjustable pistol stabilizing brace in black reinforced polymer with flexible elastomer support fits over the Mil-Spec 6-position carbine buffer tube and closes out the rear end with a 5-position adjustable length, an adjustable hook-and-loop arm strap, an integrated ambidextrous QD sling socket, and an integrated sling loop that together give the builder two sling attachment options built directly into the brace body. The all-black finish across both the lower receiver and the SBA3 brace gives this lower kit a clean and consistent exterior from receiver to brace.
