PRODUCT DESCRIPTION

Machine translated

WARNING! On the box you will find a label indicating the firearm model and power >24J, i.e. higher than 24J (see photo). Gamo manufactures its guns in several power versions in connection with different legislation on foreign markets. We currently have in stock Gamo Swarm Magnum PRO Gen3 in 4.5mm calibre with 28J power.

Gamo Swarm Magnum Pro Gen3 24

The Spanish manufacturer Gamo is churning out one air rifle after another and this time it comes with the third generation of the popular break-barrel Swarm Magnum Pro GEN3i.

The most interesting feature is the use of a 10-shot magazine, which is automatically reloaded with every cocking of the air rifle (breaking the barrel). Thanks to this you do not have to slowly insert pellets into the barrel one by one.

The barrel with a typical length of 450mm is finished with an efficient Whisper Fusion sound moderator and instead of a traditional spring it uses an IGT gas piston (Inert Gas Technology), which ensures lower recoil and vibration when firing.

The 11mm mounting rail RRR (Recoil Reducing Rail) also reduces recoil and thus extends the service life of the scope.

The air rifle is equipped with a 2-stage sport trigger CAT (Custom Action Trigger), with a manual safety located in front of it.

The polymer stock features textured sections in the grip area, fore-end and fixed cheek piece, and overall comfort is further improved by a rubber butt pad.

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.

Mr B., 29.05.2025
The 177 cal Is the version with 28J if I'm reading correctly. Is this more easy to reload ( pull ) than the standard 36J version or the required force is the same?
