PRODUCT DESCRIPTION

WARNING! You will find a label on the box stating the gun model and the power >24J, i.e. higher than 24J (see picture). Gamo produces their guns in multiple power variations due to different legislation in foreign markets. We currently offer the Gamo Swarm Magnum PRO Gen3 in 4.5mm caliber model with 28J energy.

Gamo Swarm Magnum Pro Gen3 24

Spanish manufacturer Gamo keeps pumping out one airgun after another and this time, they come up with a third generation of the popular model Swarm Magnum Pro GEN3i.

The most exciting feature is definitely the 10-round magazine, which automatically reloads each time the airgun is cocked. Thanks to that, you don't have to tediously insert pellets into the barrel one at a time.

The barrel, with a typical length of 450mm is fitted with an effective Whisper Fusion sound moderator and instead of a conventional spring it utilizes an IGT piston (Inert Gas Technology), resulting in reduced recoil and vibration when fired.

That’s further enhanced by the 11mm Recoil Reducing Rail (RRR) which greatly prolongs the durability of the riflescope.

The air rifle is equipped with a 2 stage Custom Action Trigger, in front of which is a manual safety.

The polymer stock features textured segments in the grip area, foregrip and the fixed cheekpiece, and the overall comfort is enhanced by a rubber buttpad.

The package also includes a Gamo 3-9X40 WR1PM riflescope.

It's not an air rifle for children and women. It's not impossible to break an air rifle, but it's pretty obvious after X number of reloads. You need strength.
