Downgrade Piston Set | 1911 | GBB | KWC

Downgrade Piston Set | 1911 | GBB – piston set for your replica

This piston set is specifically designed for 1911 GBB (gas blowback) pistols and limits the power to 1.0 joule. You use this GBB piston set when your replica must comply with stricter power requirements for CQB fields or when local regulations prescribe a lower power output. Replacing your current piston set is an effective method to reduce the muzzle velocity of your 1911 whilst maintaining the blowback function.

Technical characteristics

The set contains multiple components manufactured from plastic with a black finish. The parts are precisely dimensioned for 1911 GBB magazines and regulate the gas flow to deliver a consistent power output of 1.0 joule. The construction offers the necessary durability for regular use during skirmishes and training sessions.

Compatibility and application

This piston set is suitable for Colt 1911 GBB replicas, including models 180512, 180521, 180522, 180524, 180525, 180529, 180530, 180531 and 180532. Installation requires disassembly of the GBB magazine and basic knowledge of gas blowback systems. This downgrade fits within builds where power restrictions apply without compromising the function of your replica.
