Converts many Gamo rifles of 25mm compression bore.WhisperVarmint ViperRaptorFusionOthersBelow our crony velocity-test at 580 F.A.S.L (atmosphere pressure) using a couple of popular pellets in the industry. Shot from a new Gamo Whisper .22 caliber Air Rifle.
(Not Going to find a lighter magnum !)
Get the optimal ENERGY from your air gun with a Vortek Custom Build Piston. When it comes to piston speed, compression rates, momentum displacement is a powerful thing. The alloy dense material machined weight forward design yielded a significant increase in fire power while damping the shot cycle.
The Bionic piston design holds two shock absorbent rings within a precise grove engagement dynamically expands during close of shot cycle. This also absorbs momentum, weight displacement and noise. At the same time combined with a Rotary rear-ball bearing support centralizes drag force during the speed of shot cycle whether be from pellet or slug resistance.
Additionally, once the ABP piston is installed increased linear beam strength reduces each cocking momentum, shot cycle latch effort and any possible compression tube gouging. Moreover, the air rifle will have an increase in fire power yielding better performance shooting light, heavy pellets or slugs! This is a measured, precise fitting advanced-piston kit that simply slides in place of the OEM piston. Pending Patent.
For EZ Installation, below pictures show examples of a GAMO ONE-PIECE trigger housing and how their Gas Spring is flipped around to assemble into the trigger housing with OEM provided washer found down inside the Gamo piston. Washer must be removed and present on rod end and the other large Body of Gas Spring down inside the Vortek Bionic Piston. NOTE, this install arrangement must be done in order for trigger to be latch safely. Very EZ Mod! Shoot further straighter! We can custom tune your Gamo.
