Current product details

The Gamo Bull Whisper 4.5mm Air Rifle is a Bull Whisper airgun for adults with an ergonomic, synthetic butt that puts out 24 Joules of power. The Black Bull has a very special barrel with a sound-moderator, the Bull Whisper; this technology reduces the sound output of a GAMO air gun significantly due to the sound dampener housed within each bull barrel. Also incorporates the precise SAT (Smooth Action Trigger) that features a smooth trigger pull that increases the rate of accuracy and provides a responsive, clean, break when you need it most. The SWA(Shock Wave Absorber) nock which provides up to 74% more absorption than standard recoil pads.

Triple R (Recoil Reducing Rail.) Developed to subdue the taxing stresses placed on your scope from the intense recoil of air guns and high-powered rifles. The RRR uses two-piece aluminium construction separated by dual polymer struts to absorb shock waves. Once mounted to the Recoil Reducing Rail, the recoil stresses to internal components of the scope are reduced by almost 100%. This model has no sighting elements, so it includes a GAMO 4X32WR scope.
