***CREEPY AS F¥€K***
Extra heavy piston body for SRS.

General info:
-CNC made carbon steel
-Original Silverback piston end REQUIRED
-Weight is 65 gram itself (assembled ~75 gram)
-Increases muzzle energy with heavy bb
-Tighter fit around the spring, reduces noise

Muzzle energy increas is HIGHLY setup dependant, early next week I will post a whole chart with the most infirmation I can provide to estimate Joule increase.

19$
