Optimise your small-bore airgun’s firing loop with our premium Weihrauch Beeman 25mm Short Stroke Piston Seal. Engineered purposefully for 25mm cylinder diameters—including the Weihrauch HW97, HW77, HW30, HW30s, and Beeman R7—this performance component features an integrated 10mm short-stroke extension. Minimising piston travel, it decreases lock time and dampens hold sensitivity to elevate downrange accuracy. A solid, one-piece unit with no pins or loose screws, it delivers a flawless, drop-in fit.

Description
Weihrauch Beeman 25mm Short Stroke Piston Seal
Upgrade Lock Speed in Smaller Cylinder Actions
Smaller compression cylinders require absolute mechanical efficiency to maintain consistency. Our Weihrauch 25mm Short Stroke Piston Seal addresses this by incorporating a 10mm structural extension directly into the compression nose piece. This one-piece solid engineering layout guarantees that you achieve a snappier shot cycle without adding heavy weights or loose clip-on spacers that threaten to dislodge inside your cylinder walls.
Drastically Reduced Hold Sensitivity & Vibration
Short-stroking is highly advantageous for compact configurations or target-focused sub-12ft/lbs setups running softer springs. Quicken the firing process to ensure the pellet leaves the muzzle before recoil forces or minor body movements shift your point of aim. Expect a clean, predictable firing cycle that strips away annoying mainspring “buzz” or tracking harshness.
