About this item
Product details
The GAMO Swarm Viper 10X GEN3i .177 pellet rifle showcases an innovative, inertia-fed design that leads the market in rapid-reload technology. The third-generation 10X GEN3i system combines a sleek, modern aesthetic with a 10-shot horizontal inertia-fed magazine. This unique system automatically indexes the magazine using the force from the rifle’s recoil, ensuring a smooth and precise breech-loading process. Simply break the barrel, fire, and enjoy incredibly fast follow-up shots. This is GAMO’s state-of-the-art rapid-reload technology in action. Equipped with Whisper Maxxim sound dampening technology, the Swarm Viper reduces noise by guiding the pellet through two chambers, compressing and containing sound expansion for a quieter shot. Powered by Inert Gas Technology (IGT), the gas piston delivers consistent, steady power, reducing vibration and enhancing both accuracy and durability. The rifle also features GAMO’s Custom Action Trigger (CAT), a two-stage adjustable trigger that offers a crisp, smooth, and clean pull for superior accuracy. Additionally, GAMO's Recoil Reducing Rail absorbs 99.9% of recoil, providing maximum scope protection and ensuring a smoother shooting experience, even with high-powered air rifles. For added comfort and control, the Swarm Viper is equipped with an automotive-grade synthetic stock and rubber grip inserts in the forearm, grip, and cheekpiece. With speeds of up to 1,300 fps using .177 caliber alloy pellets, this air rifle is an ideal choice for pest control and hunting. Combining the latest in GAMO technology, the Swarm Viper 10X GEN3i delivers exceptional performance, making it the perfect solution for both recreational shooters and serious hunters.
