Things I liked:A quality product that works well
Things I would have changed:Item is expensive, need to reduce the price
Things I liked:Easy to load gas and BBs. Nice and heavy. Realistic to have both gas and BBs in the magazine together.
Things I would have changed:Both of the magazines I have leak after shooting. Multiple shots make it leak more, and full-auto is worst. The valve gets iced-up. A heat gun is handy to thaw it, and the leak will cease. The valve spring is very soft, perhaps it needs to be to operate the blowback, but it's disappointing to have to check the magazine for leaks every time you shoot.
What others should know:I always use a fat drop of Pelgunoil on the top of every new CO2 cartridge, but it does not augment the leaks.
Things I liked:Well made and nice to have a spare. Spring for the BB follower seems well made , strong and durable like the original. Heavy.
Things I would have changed:Nothing
What others should know:Nice to have a spare and looks and function's great - no jams - smooth feed.
