Features GAMO SWARM MAGNUM PRO 8X GEN3i AIR RIFLE

Gamo Swarm Magnum Pro 8X Gen3i: power, accuracy and multi-shot technology

The Gamo Swarm Magnum Pro 8X Gen3i is an air rifle developed specifically for 6.35 mm (.25) calibre. It combines the 8X Gen3i multi-shot system with an IGT Mach 1 gas piston, Whisper Fusion sound moderation and an included Gamo 3-9x40 scope.

The version supplied by Carbin produces approximately 20 joules and is intended for recreational target shooting and plinking on authorised ranges.

Gamo Swarm Magnum Pro 8X Gen3i technologies

• 8X Gen3i: multi-shot system with an eight-pellet horizontal inertia-fed magazine. The barrel must still be broken and closed before every shot.
• Whisper Fusion: integrated sound moderator that helps reduce the report produced by the shot.
• IGT Mach 1: gas piston replacing the traditional steel spring to provide consistent operation and reduce mechanical vibration.
• CAT: adjustable two-stage trigger that allows the first- and second-stage travel to be personalised.
• RRR: Recoil Reducing Rail designed to reduce the stress transferred to the scope and mounts.
• SWA: recoil pad with removable inserts for adjustable cushioning.

Eight-pellet horizontal inertia-fed magazine

The 8X Gen3i system uses a low-profile magazine that indexes through the inertia generated during the firing cycle. It holds eight pellets and reduces the height of the multi-shot assembly above the action.

This remains a break-barrel air rifle: after every shot, the barrel must be broken to cock the gas piston and feed the next pellet. For help with generations, calibres and compatibility, read our guide to choosing the correct Gamo magazine.

6.35 mm calibre and 20-joule specification

This version of the Swarm Magnum Pro 8X Gen3i is chambered exclusively for 6.35 mm (.25) pellets. The configuration supplied by Carbin produces approximately 20 joules and is designed for lead pellets of this calibre.

The durable synthetic stock supports a stable shooting position. Its rifled steel barrel helps stabilise the pellet, while the SWA recoil pad cushions the rifle’s reaction during the shot.

Gamo 3-9x40 WR1PM scope included

The rifle includes a Gamo 3-9x40 WR1PM scope with variable 3x to 9x magnification and a 40 mm objective lens. It is installed on the RRR rail, which is designed to reduce the recoil forces transferred to the optic.

Before use, the scope must be correctly installed and zeroed with the pellets and shooting distance normally used.

Compatible magazine

This model uses the specific Gamo 8X Gen3i eight-pellet magazine, reference 6212672. It must not be confused with the 10X magazines used by other Gamo air rifles in 4.5 and 5.5 mm calibres.

The 8X Gen3i system refers to Gamo’s third-generation 8-shot rotary magazine. The "i" stands for "inertia", indicating a smoother, quieter indexing mechanism that allows fast and precise semi-automatic follow-up shots with no manual loading between pellets.

The 6.35 mm (.25) caliber delivers around 20 joules of energy, offering strong knock-down power and impact at short to medium distances. This power level complies with Spanish regulations; check your local laws before purchasing.
