All of the gas pistons sold on my website are heat treated after machining.  All are made of stainless steel.  When deciding on which piston to buy ask the other places if their pistons are heat treated, you might be surprised by their answer.

Each gas piston comes with a new rivet for installation so there is no need to order a rivet with a piston unless it's for a spare.
