Armaspec Sound Mitigation Carbine Buffer, Gen 3 – 3.3 oz

The Armaspec Sound Mitigation Carbine Buffer, Gen 3 (brand part number ARM258-C) is built to keep the buffer spring from rattling against the inner wall of the buffer tube, quieting an AR-15’s action for smoother, less distracting cycling. Armaspec engineers the Gen 3 buffer at 3.3 ounces, giving builders a specific weight point for tuning felt recoil and cycling speed against their gas system and spring combination. Because buffer weight is one of the simplest ways to fine-tune an AR’s cycling behavior, this Gen 3 model lets shooters dial in smoother, quieter operation without replacing the spring or tube. It’s a straightforward internal upgrade for anyone chasing a smoother-shooting carbine.
