G&P SR-25 L85 Type Polycarbonate Reinforced Piston for Airsoft AEG

2 Customer Reviews

"This piston deserves a 5. The 3 reinforced teeth actually is "ALOT" of reinforcement as thats where most of the strips happens, which carries to the rest of the teeth.

It will last probably 100,000 more rounds than the stock piston in an Army L85.

"I bought this for the ARMY L85 and it is slightly more reinforced than the stock piston with the first 3 teeth being metal instead of just the first tooth. It has a different venting pattern than stock that I guess is supposed to help create a better seal to the cylinder--the stock one just has several holes around the piston head versus this pistons three long vents. However, the blowback action of the L85 broke the back of this piston so I had to disable it permanently. 4 stars just because its only reinforced on the teeth and really nowhere else.
