Description
The Air Venturi OmniStorm™ is a break barrel air rifle like no other! Available in .177 or .22 caliber, it is a power-adjustable, single-shot break barrel. Thanks to the innovative OmniPiston™ gas piston powerplant, users can quickly adjust the pressure within the piston to change the power and cocking effort of the rifle. This is done with the included OmniTuner pump and allows kids to use the same rifle as their parents with a simple adjustment! Additionally, the OmniPiston™ is a set it and forget it system, meaning once you have the gun performing the way you want, it will remain at that setting.
When it comes to adjustment, the OmniPiston™ powerplant operates from approximately 205 PSI to around 550 PSI. Cocking effort increases with pressure, ranging from 25 lbs on the low end, to about 50 lbs. As pressure and cocking effort are increased, so is the velocity and power capability of the rifle. In .177 caliber, 7 grain lead pellets reach speeds between 500 - 1,100 FPS and 11.9 grain .22 cal lead pellets travel between 500 - 850 FPS.
The rifle is built around an all-weather synthetic stock and boasts a pair of adjustable fiber optic sights and an 11mm dovetail rail for the included 4x32 scope. A two-stage trigger and a 19” rifled barrel help land accurate shots while an automatic safety prevents unintended discharges.
This gas piston rifle is great for hunting small game animals, pest control, teaching beginner fundamentals, or acting as a survival rifle with its own power source. If you’re in the market for a new, innovative break barrel air rifle, look no further. Buy your Air Venturi OmniStorm from Pyramyd AIR, today.
