CNC Stainless Steel Piston Head for Silverback SRS & TAC-41

Upgrade your Silverback sniper rifle with this precision CNC-machined stainless steel piston head, designed to improve durability, consistency, and overall performance. The increased piston head mass enhances the efficiency of the compression system and delivers a smoother shot cycle.

Available in No Airbrake, Short Airbrake, Medium Airbrake, and Long Airbrake versions (for 4.60 mm internal nozzle, compatible with the TAC-41 GBB cylinder head only).

Features

• Precision CNC-machined stainless steel construction
• High-quality Viton O-ring with ventilated design
• Durable POM piston ring
• NBR 80° O-ring damper for reduced impact

What Does an Airbrake Do?

An airbrake restricts the airflow just before the piston reaches the end of the cylinder, creating a cushion of compressed air that reduces piston impact and significantly lowers firing noise.

Note: Depending on the airbrake length, a slight reduction in muzzle energy may occur.
