German quality and loaded with features, the Hammerli 850 AirMagnum is so much fun to shoot that you'll have a hard time putting it down.

Let's start with the all-weather stock. You can take this gun anywhere and not worry about a fragile finish, because it's made from a durable polymer. It's ambidextrous, too, with a raised cheekpiece on both sides of the Monte Carlo stock! This CO2 rifle uses an 88-gram AirSource cartridge, giving you up to 200 shots before you have to change cartridges. The fiber-optic sights will help you acquire your target, but feel free to mount a scope on the 11mm dovetail rail. (Umarex also makes a dovetail-to-Weaver mount; check the Accessories link below.) The checkering on the pistol grip and forearm will help you get a good grip while you plow shot after shot from this 8-shot repeater. This gun is everything you ever hoped for in a CO2 repeater!

We've recommended some pellets to help you get the most from this airgun. Check out the AMMO link. Remember to click on the ACCESSORIES link to get extra magazines and AirSource cartridges and to select appropriate scopes, mounts and other shooting gear.

Things I liked: I have only about 100 pellets thru the gun since I bought it and I am happy with its accuracy, feel and especially the trigger. This is my first moderately priced rifle and I should have gotten it long ago. So far absolutely no complaints

Things I would have changed: nothing so far

What others should know: I got an 88 gm CO2 to 12 gm adapter from China for about $10, but it was only 5 inches long so changing the 12 gm cylinder would have been a problem, so I made an extension for it from a 1" to 3/4" reducing copper coupling, a cap for the 3/4 " pipe and about 3" of copper pipe. I then put 4 bolts thru the cap, with a short bushing on each, so twisting the cover for the 12 gm cylinder would be easy. Works like a charm and no $!00 adapter needed. You need to attach the nipple to the housing and I used a short bolt, but careful it is not too long and interferes with the seating of the cylinder.

Things I liked: I love this gun! It is one hole accurate at 12 yards (all the room I have at home) with JSB Exact 14.3 gr. and RWS Hobby pellets. Mine is a .22 cal. and with the optional muzzle brake taped, it is next to silent. If you buy this gun, be sure to get extra magazines for it because you will want to shoot a lot. I bought the 12 gram CO2 adapter because the large 88-90 gram CO2 cartridges are hard to find in my area. I found that I have to place a penny between the two 12 gram cartridges to insure that both cartridges would get pierced. I like shooting this thing so much that I have gone through about 300 pellets so far in about 3 weeks. I have no doubts that it would take squirrels or birds at reasonable ranges because of the accuracy.

Things I would have changed: A bulk fill option for CO2 would be nice.

What others should know: The bolt needs to be operated smartly to avoid jams. Some pellets are too long to fit properly in the magazine. Pyramyd Air is a pleasure to work with.

  • John from USA asked:

    There is on the internet a conversion unit which will allow a 12 gm CO2 cartridge to replace the 88 gm one. It is only 5 inches long. Would this allow changing the 12 gm cartridge without removing the adapter?

    • Robert from USA asked:

      Does someone make an affordable wood stock for the gun

      • Bill from USA asked:

        How do you move front sight to adjust aim?

        • ahkell from USA:

          Just like setting elevation on your M4

        • ahkell from USA:

          opposite poi. Front post up, impact will be lower. Post down, impact higher. post left, impact right etc. Got it? The opposite way that the rear sight works.
