The Gamo G-Challenger IGT 4.5mm Air Rifle includes a cold-hammered barrel, beechwood & ergonomic design for competition purposes. This rifle also has a laser engraving on the handguard, and both its cheekpiece and nock are adjustable.

It incorporates the IGT system (Inert Gas Technology), a system which replaces the traditional spring and offers several advantages, among which are greater regularity, reduced vibration and greater accuracy. The SAT trigger is the latest GAMO trigger technology and it is included in this model to control your shot like never before.

Triple R (Recoil Reducing Rail) was 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 shockwaves. Once mounted to the Recoil Reducing Rail, the recoil stresses to internal components of the scope are reduced by almost 100%.
