"I purchased this piston along with the AC spring guide, AC sp150 spring, and speed airsoft trigger and piston sears. The only wear I've had on this setup is a very minimal amount of the anodized finish wearing at the corners of the piston sear, but no wear on the actual metal, which is actually made out of cnc steel ( I contacted speed airsoft). As far as the piston goes, assuming you still have the stock piston, take the O-ring off of the stock piston and put it on the new piston, and you have perfect compression. Overall 5/5 on the piston, besides the O-ring.

"You can't beat the price on this. Great quality item. The construction is nice, and the back end stainless steel part looks like it should hold up to a lot of shooting. If you're looking for a 45 degree upgrade piston, this is the best value for your money. It has an air break on the front, and some padded material to reduce the force on your gun.
