Building on the success of a long-time CO2 favorite, the Hammerli 850 AirMagnum, Umarex delivers the 850M2 with a handful of desirable upgrades. Maintaining the same high quality performance as its predecessor, users can expect tack diving accuracy, smooth operation and rugged reliability from this rifle.  

The 8-shot magazines in both .177 and .22 caliber cycle smoothly with the operation of the side bolt. This gun is made to shoot all day, and that is backed up by an impressive 200 shots per 88 gram CO2 cartridge! Take aim with the fiber optic sights, or mount a scope to the 11mm dovetail and see what this rifle can do. Additionally, the 850M2 features a 1/2" UNF threaded muzzle so you can add your favorite moderator or compensator.

The stock comes with a few upgrades over the original. The removable cover that keeps your CO2 cartridge hidden now features three picatinny rail sections for accessories.  These will come in handy for those that want to mount a bipod, lights and lasers.  There is also more texturing on the grip and fore-end of the stock to provide a firm and secure grip while you shoot  The ambidextrous stock also features a clip on raised cheek piece which will provide a firm cheek weld for scoped shooters. 

Whether you're looking to eliminate small game in the backyard, or drop tin cans with authority, the Umarex 850M2 is perfectly suited to handle all of your airgunning needs!
