Things I liked: Comfortable fit and feel to the 850. With 3-9 x 50 scope installed, zeroed it at 11 yards with JSB Heavys (18.13 gr). Very good grouping through 32 shots. Moved back to 29 yards and shot another 16 pellets - forgot co2 velocity drops in cold weather (36 degrees) and my shots progressive hit lower on target. I was using the Umarex adapter with 2 co2 cartridges so I was also getting low on co2. I'll wait until warmer weather to zero it at longer ranges.
Things I would have changed: Nothing at this time.
What others should know: Co2 velocity changes about 2 fps per degree F. which I had forgot. If it is cold outside your shots will start dropping lower as the rifle cools off.
Things I liked: it's a very excellent co2 airgun in the market.
Things I would have changed: none
Things I liked: accurate, plenty of power for metal targets pt 20 yards.
Things I would have changed: an adapter for 12 0z co2 would be nice. the 88 oz are great but it is hard to shoot enough to put gun up empty. 88 oz is good for over 200 rounds.

What does the screw, recessed on the right side, between the safety and mag release slide lever do? Looks like an adjustment of some kind? Also, are there any easy/quick, (or not), ways to increase power? Thanks RAN
Can you tell me the proper way to remove the 88 gram tank from the gun without damage to the o-ring?
Unscrew it, pretty simple
I asked the question below and it was suggested I call Umerex. I did and they said the Air Venturi bottles are not compatible. Sure enough, all 88/90 gram CO2 cylinders are not created equal. Some have a longer nipple (Air Venturi)than others. The longer nipple prevents proper seating against the O-ring. Has anyone else experienced this? Q. - The o-ring in my 850 failed to hold pressure so I ordered three new ones from Umerex. While screwing in a cylinder the new o-ring blows a second or two after the cylinder in punctured. I tried several times with another new o-ring with the same result. wtf?
I have seen it before with the Sig MPX/MCX, some guns seem less prone to have issues with the varied 88/90 gram cylinders than others.
