Browning gas piston

Machined from 416 stainless steel and skeletonized to reduce weight this replacement gas piston is more durable than the original aluminum factory part. The piston is supplied with stainless steel outer seal ring and lock ring and an aluminum wrench. The internal parts of the factory original piston need to be removed and used in the replacement piston. The lock ring on the factory piston is Loctited and may require heat to loosen.
