Sniper Mechanics - SRS W.A.S.P

The original Weight Adjustable Silent Piston (W.A.S.P) for the Silverback SRS, back with an improved design and material tweaks.

The piston weight is tuned with three interchangeable sleeves (light plastic, medium steel and heavy steel), so you can match the piston mass to your spring rather than accept what the rifle came with. Three front fittings set how much air cushions the end of the stroke: no airbrake, a mid brake or a full airbrake. It comes with a one-piece stainless steel spring guide, and spring guide O-rings to suit both the old and new generations of SRS buttpad.

The SRS W.A.S.P package features

• 1× SRS W.A.S.P base piston body
• 1× rear sear
• 1× rear guide ring
• 1× front securing ring
• 1× plastic sleeve (light)
• 1× steel sleeve (medium)
• 1× steel sleeve (heavy)
• 1× non-airbrake fitting
• 1× full airbrake
• 1× mid brake
• 1× injection-moulded cup
• 1× one-piece stainless steel spring guide
• Spring guide O-rings (old and new buttpad generations)

Note: the airbrake only adds power over the non-airbraked setup up to a point. Beyond that "break point", which depends on your setup, the spring and piston overpower the airbrake and it slows the air too much. Tune with the included fittings and sleeves.

Fitment: Silverback SRS. For the VSR-10, see the VSR W.A.S.P.
