Gives New Life & Performance To The SX 1

Competition grade parts restore performance to better than new. Stainless steel magazine tube is stronger than original; resists pitting and corrosion. Neoprene bolt buffer replaces those cracked from age and use. Extra power, chrome silicon, hammer spring gives faster locktime. Durable steel rebound follower replaces factory aluminum part. Chrome silicon rebound spring won't take a set, prevents battering action. "O" ring, resistant to heat and gas deterioration, cures many cycling problems.
