Things I liked:magazine, blowback action, and accuracy Things I would have changed:reliability What others should know:initially i really liked this bb gun, it was fun to shoot and very accurate. however, after shooting less than 250 bb's i began having problems with it. the gun will at random completely empty a brand new co2 cartridge within the first 5 shots. prior to that problem i would experience occasional misfires that would result with 2 bb's stuck in the barrel - very annoying to have to find something to ram the barrel with to clear it. i thought this bb gun would have been a good trainer to shoot in the back yard, but in hindsight i should have just bought cb caps for my .22 rimfire.
