You cock it like a spring gun, but the gas strut does not take a set when left cocked, cycles with less vibration and twang, and stays consistent across temperature changes.About the CaliberThe .177 caliber (4.5 mm) is the most common airgun caliber. Its light, fast projectiles shoot flat, which makes it a favorite for target shooting, plinking and small pests at modest ranges.Specifications ExplainedGamo rates velocity at 1. Published velocity is measured with the ammunition type the manufacturer lists; heavier pellets will shoot slower but often carry more energy.Muzzle energy is listed as 33.19 ft/lbs - 45 J. Energy, not just velocity, is what matters for pest control and small game, where legal.The barrel is listed as Metal jacketed rifled steel barrel. A rifled barrel spins the pellet for accuracy.Trigger: Two stage independently adjustable CAT (Custom Action Trigger). A predictable trigger is one of the biggest factors in accurate shooting.For aiming, the manufacturer lists GAMO 3-9x40 air rifle scope with rings (shockproof, fogproof). Check the rail type before buying rings or a dot sight.The safety is listed as Manual safety and automatic cocking safety system*. Learn how it works from the owner's manual before loading.Getting Started and CareBefore the first session, read the owner's manual, check that the gun is unloaded, and set up a safe backstop or pellet trap. Shoot from a rest to confirm where the gun hits at your usual distance, then adjust the sights or scope.Try several brands and weights of quality .177 pellets of the type the manufacturer lists. Airguns often prefer one pellet over another, and finding it is the quickest way to tighter groups.Break-barrel and gas-piston airguns are hold-sensitive. Use a light, consistent hold, let the gun recoil naturally, and never dry-fire it. Clean the barrel only as the manufacturer recommends.Safety and Local LawsTreat every airgun as if it were loaded, keep the muzzle pointed in a safe direction, and keep your finger off the trigger until you're ready to shoot. Shooters and anyone nearby should wear eye protection. Airgun laws vary by state and city, including age limits and where you can shoot, so check your local rules before ordering. Airguns are not toys and must be used with adult supervision by younger shooters. Store the airgun unloaded and out of reach of children, with ammunition stored separately.Shop More Air GunsPair this air rifle with the right ammunition from our air gun ammo, and compare it with other air rifles.Product SpecificationsManufacturer: GamoBrand: GamoModel: Swarm Magnum 10X GEN3I Inertia Fed .177 Caliber 10-Shot Air RifleManufacturer Part Number: 6110038654UPC: 793676095080Caliber: .177Velocity: 1Action: 10X GEN3i Ten-Shot Auto-Loading TechnologyNoise dampening: Whisper FusionPowerplant: IGT Mach 1 Inert Gas Technology gas piston (33 mm cylinder)Barrel: Metal jacketed rifled steel barrelTrigger: Two stage independently adjustable CAT (Custom Action Trigger)Stock: Automotive grade glass filled nylon all-weather thumbholeCheckering: Non-Slip texture design on grip and forearmRecoil Pad: SWA (Shock Wave Absorber) Recoil pad with up to 74% recoil absorptionSafety: Manual safety and automatic cocking safety system*Optics: GAMO 3-9x40 air rifle scope with rings (shockproof, fogproof)Rail: 11 mm aluminum rail, RRR (Recoil Reducing Rail)Weight: 6.88 lbsLength: 49.2 inLength of Pull: 15 inAmmunition: Any .177 Cal.
