WARNING! On the box you will find a label indicating the weapon model and power >24J, i.e. higher than 24J (see photo). Gamo manufactures its guns in several power versions in connection with differing legislation on foreign markets. We currently have in stock Gamo Swarm Magnum PRO Gen3 calibre 5.5mm with 35J power.

The Spanish manufacturer Gamo is turning 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 each 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 fitted with an effective 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 riflescope.
The air rifle is equipped with a 2-stage sport trigger CAT (Custom Action Trigger), in front of which there is a manual safety.
The polymer stock features textured panels in the area of the grip, fore-end and fixed cheekpiece, and overall comfort is further enhanced by a rubber buttpad.
The package also includes a Gamo 3-9X40 WR1PM riflescope.

Excellent, powerful and surprisingly very accurate rifle. I am satisfied.
The rifle is quite heavy and may not suit women and certainly not children. The
ammunition that has worked well for me is JSB EXACT JUMBO 5.52mm.
The exact length of the gun is 127 cm, so buy a 130 cm case. I gave the
supplied riflescope to my colleague and I use a Valiant Themys II with an
etched reticle. I wish you a lot of fun with your new rifle

Wiatrowa is surprisingly accurate! I'm shocked that for this price you can have
such an accurate carbine; at 50m with H&N Baracuda Hunter pellets (hollow
point), I managed to make a 2cm group at 50m… The carbine taken straight out
of the box. Incredible. Highly recommend to everyone.

The rifle is good but it is a purchase that needs to be thought about, the
handling and the multi-shot system are excellent, the cocking does not require
immense force either. However, with the scope it starts to become heavy, if you
do not shoot with support you will quickly feel the weight. The power is much
lower than the 35J announced by Gamo, I get 28J with JSB EXACT 4.52 in 1.03g,
I am below 240m/s which is quite slow for a 5.5mm. I do not recommend it if
you want to shoot at arm's length without any support.

Despite the higher weight, it is a good choice for shooting at longer distances.
I like the placement of the safety, I don't have to fumble. I haven't
measured the joules, but at 40 yards it will shoot through 2cm furniture grade
particle board like nothing.
