I've had one for 5 yrs. Absolutely love hunting duck and geese with it.
i shoot 3" with mine, my son shoots 2 3/4 with his.
Watch out for the finish. the cheap cleaners, like walmart stuff, will eat the finish off in a heartbeat. The finish is a powder coat type, not blued.
Only thing I don't like is if you want to buy parts, you can't. you have to send the gun to OK, they fix it and send it back.
I bought o rings for the piston at Park rose Hardware and I changed the plastic magazine follwer cup to an all stainless set designed for Winchester, they are the same size.
Keep them oiled good and they run like crazy. I fired mine underwater and it cycled perfect. I cleaned it afterward, but it was fun.
Don't use a lot of heavy oil in freezing weather, they get tempermental.
