The Armaspec Sound Mitigation AR10 Buffer, Gen 3 (brand part number ARM258-AR10) is built to keep the buffer spring from rattling against the inner wall of the buffer tube on an AR10 or 6.5 Creedmoor build, quieting the action for smoother, less distracting cycling. Armaspec engineers this buffer at 4.7 ounces, giving AR10-platform 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 AR10 or 6.5 Creedmoor rifle.
