It is fair to say that one of the most common air rifles about is the Chinese B2 rifle, This is mainly due to price and the fact they have been around for years. I purchased my first one about 6 years ago for the princely sum of £20.00.
Any one who is familar with these guns will know that they are generally poor quality, particulary the stocks, usually coated in a thick brown finish that is very difficult to removed, and when removed usually reveals where the stock has been filled. the gun is an all metal break barrel with a release mechanism for the barrel so you dont have to force it open to cock. Single stage trigger which is heavy.
These guns get critisied heavily by a lot of gun snobs but they are responsible for a lot of people getting into the sport and then buying better guns as they progress. It has been said that they could put people off because they can be inacurate but then a £600.00 gun can be inaccurate to the same degree with the wrong pellets. You have to persist with a new gun until you find the make of pellets the barrel shoots well and you have to get a few 100 pellets through it to settle it down, a B2 is no different just not as fancy or as powerfull.
Overall an excelent plinker, good gun to work on and improve. If you fancy having a garden plinker for some fun for not a lot of money this is the place to start.
