GAMO G‑Challenger IGT — Competition‑Grade .177 Air Rifle (4.5mm)
The Gamo G‑Challenger IGT is built for precision shooters who want competition‑level performance without fuss. Its cold‑hammered barrel and rigid fixed‑barrel design deliver excellent consistency at short to medium ranges, while the beechwood ergonomic stock and adjustable cheekpiece allow you to set a natural, repeatable cheek weld for tighter groups. Subtle laser engraving on the handguard gives the rifle a refined look that matches its performance.
Under the skin the IGT (Inert Gas Technology) piston replaces the traditional mainspring to cut vibration, improve shot‑to‑shot regularity and extend service life. Pair that with GAMO’s SAT trigger and the Triple R (Recoil Reducing Rail) system and you get a controllable, low‑stress shooting platform that protects optics and keeps follow‑up shots predictable. Light enough to carry yet stable on the bench, the G‑Challenger IGT is a smart choice for target shooters and serious plinkers alike.
