The TacFire Buffer Retainer Pin & Spring 10-Pack is a bulk set of AR-15 buffer tube hardware from TacFire (brand part no. MAR086-10PK) built from piano wire for a 6-position buffer tube design. Each retainer pin and spring pair secures the buffer inside the tube and helps reduce the "twang" vibration heard when firing an AR, keeping the rifle running quieter and smoother. Sold as a 10-pack, it’s a practical option for shops, armorers, or builders who need spares on hand across multiple AR-15 builds instead of buying single retainer sets one at a time.
