Firing Pin AR15 – 22 rimfire
We’ve brought back out famous 22RF firing pin!! The chisel point on the front of our firing pin will give you the very best chance of ignition. We use 17-4 Stainless Steel because it is stronger and tougher than S7, 4140 tool steel, which is your more common material used on other firing pins used in the market.
