For a kids introduction to see if they like the sport It is fine and is probably responsible for getting thousands of shooters into the sport in the first place.But for an out of the box gun they are at best a back garden plinker.Don't get me wrong I like Chinese guns and have many of them.But there are better to be had if on the other hand you like to tinker then they can be made to shoot well with little effort.They will never win any beauty competitions but will keep you amused for a long time.But for long range which is where you have posted.Then forget it No cheap gun will ever be able to match up to the top end springers for long range target shooting.There are a few in the SMK range that will do the business but even they require a decent aftermarket spring and lube tune. The B2 is an entry level first time gun and should be treated as such,not ridiculed for it's short commings.Remember it is a 45 year old design (a Diana design at that) and therefor can not be expected to be up with the modern designs.The other factor in the equation is that they almost always give you SMK pellets with the guns these are best used as fishing weights or just very short ranges, they make any gun look rubbish.
