Gamo Swarm Magnum Pro 8X GEN3i .25 Cal
Original price was: $523.99.$499.99Current price is: $499.99.
Gamo Swarm Magnum Pro 8X GEN3i Multi-shot breakbarrel .25 caliber air rifle. This features the “Inertia” advancing magazine. The recoil of the rifle causes the magazine to advance to the next round. This system avoids the “double-feed.” This is the exact rifle in my October 03, 2025. So, if you would like more information, please review the listed video. The rifle is “as New,” with less than 80 shots through it. It produces approximately 33 FPE, combined with outstanding accuracy, makes this rifle a Hunter’s Dream. This rifle has been upgraded to include the installed, Trigger Screw kit ($9.99), the Gen 2 Bipod kit ($65.99) and an upgraded scope, BSA Outlook 3-9 x40 AO Mil-Dot “Airgun Rated” Scope ($97.99). The Recoil Reducing Rail (RRR) has been modified to accept standard scope rings with the stop pin (See attached photos). The trigger on this rifle now breaks at 1 lbs. 11 oz., over the stock 4 lbs. trigger. This rifle comes in the original box and packaging. The original “New” 3-9 x 40 Gamo scope is included. This specific rifle is extremely accurate! Again, you can see the entire review on this specific rifle, which is much better than any 10 for 10 testing.
