Magazine Fed Break-Action Air Rifle? GAMO Syes Yep with the Swarm Maxxim Air Rifle

While gunpowder more than gets the job done in most cases, its often possible that simple compressed gas can as well. Being fortunate to have reviewed multiple air rifles, I can attest that for certain circumstances (like anything one might shoot with a .22 LR), that they are excellent options for hunting, training, or legal compliance. Many cities do not allow firearms discharges within city limits, so air rifles are great to get around the rule.

The bane of many air rifles, especially break-actions has been the slow loading time. Until now, they have been single-shot weapons. GAMO has seen to correct this with the introduction of their latest air rifle, the Swarm Maxximwhich incorporates a 10-shot magazine into the break-action air rifle.

It’s not the only innovation too, namely their Recoil Reducing Rail system, which (finally) brings air rifles into parts commonality with modern firearms through a picatinny rail adapter that seeks to reduce the harsh vibrations of air rifle recoil so that most scopes can handle it. Combined with the SWA recoil pad, the air rifle will be extremely pleasant to shoot and soft on both optic and shoulder.

Finally, the common spring and piston powerplant has been replaced by pneumatic cylinders, which uses compressed gas instead of the normal compressed spring. GAMO claims this more consistent pressure, holding the .22 caliber pellets within a 40 FPS velocity range. The .177 pellets scream out the rifle at 1300 FPS.

Retail is set at $199. It is currently in-stock over at Pyramid Air and shows availabiltiy from Cableas, AirGunDepot, and other sources.

    You have the .22 and .177 velocities reversed. The .22 goes 975FPS, the .177 goes 1300FPS, both with the lightweight lead-free pellets.

    For reference, the lead .177 pellets weigh 7-10 grains, while the PBA type weigh 4.7-7.1 grains.

    Lead .22 pellets weigh 14-26 grains, while the PBA type weigh 10-14 grains.

      Nifty. Drives me bonkers when they quote velocity without mass.

      Peoole on airgun forums act like it doesn’t matter compared to accuracy, false dichotomy, or one should just know. I’m just like “ok, we real gun users bother to note the weight of the projectile but I guess you pizza-roll goblins’ time is more valuable”.

      • Kelly Jackson

        These hyper velocities with airguns were achived by usuing really light weight pellets and the whole thing seems really counterproductive.

        Pellets generaelly aren’t stable at super sonic speeds so to push a low mass one beyond 1,000fps seems to be rather silly. I’d rather see a heavier projectile hitting in the 900 – 1000fps range.

          There is a reason that Air Rifles used in the Olympics shoot in the neighborhood of 500-600 FPS. For extreme accuracy in an air rifle that is the butter zone. I just don’t get a break barrel air rifle with a magazine. The mag kind of reminds me of unhealthy growth.

        Lol @ pizza-roll goblins.

  • Brett baker

    Still waiting for the M4 semi-auto clone. The new SIG gets close though.

    Yeah, no, it’s Gamo.

    Better wait til somebody makes the same thing that actually works. And the velocities are for the ultra light ammo that weighs less than half of regular ammo. Realistically you can expect 600 fps out of the .22 version.
