I prefer goods made in the U.S.A, but the price on these chinese air rifles is hard to beat for a novice air gunner wanting to give the sport a try.
Much higher quality than I expected for $20. The sights are a little coarse and I believe the dovetail is an odd size (I still made a cheap wally-world Tasco fit on with no problems). It sure aint pretty, either. But it does perform. Relatively accurate, and 900fps. That will ruin a squirrel's day.
I am not an airgun expert, but I think you will be pleased with the performance for the price.
Good luck with whatever you choose.
