just bought two of these air rifles on a gun show. To my suprise both rifles were NEVER been used. The gentleman at the booth had it with instructions manual and original box in .22 caliber.
In fact these are my first .22 pellet rifles and gotta tell you its addictive that extra bullet size. Now it does feel very realistic, the .22 caliber plus the recoil action of the springer its a plus, makes it very authentic.
This is a sidelever one shot rifle, the spring is pre-loaded from factory. The rifle is made by Industry (AKA Xisico), the company stopped production or better say, distribution to the US many years ago. To find one, and in this case two, in brand new boxes its simply amazing. I am planning on adding a M1 or R15 magazine to give it a realistic more menacing look. At least the ones I have are very accurate from 10 to 20 yards.
Do not expect to win the Olympics with them, they are simply fun to shoot, too much indeed. To give you some insight, the Chinese army contractors made them as part of a training program for their soldiers. So these carbines have the feel, roughness and weight of a authentic combat assault rifle. Of course one can detect some short-cuts in production to keep costs down, but this is what makes them such perfect projects guns. With a little of tuning, cleaning, honing the chambers these bad boys can put down squirrels, racoons, on its track within 30 yards.
If you like this model, would recommend also the XS-b3-1, which I was lucky enough to score one new at the same gun show.
Highly recommended for what its worth. Does not compare to cheap Crosman, Daisy, Gamo toy feel of those other brands. Chinese QB6 will last for many years, solid steel in all mechanisms, only plastic is the grip (nothing a gun outlet cant fix).
