Tech Force B50

It is a copy and I have seen them tuned to shoot very well. They may require some smithing to get consistent and accurate however.
 
It can be an excelent rifle,

If using the stock barrel you most likely will need to re-crown it then groups may be good enough. You would want to change the hammer spring (four screws to remove) maybe polish the hammer and adjust the trigger down to about 8-9 ounces (as low as it will safely go unless you work on it).
Our .22 B50 with a 25" .22 barrel using JSB 15.9g at 1025fps is a true sub-moa rifle at 100yards if the wind isnt too bad.
One of my other posts has pictures of ChrisK's Bam bench rest stock, 3" wide on the front botton, acccessory rail ..... .
Chris complied a lot of Bam info here:

Have you looked at the

Crosman Discovery?
Tim at Mac1 will go over the rifle to make sure there are no problems! And you can have him add adustable power control. All for a few buck more. Beat that! :D . On the downside the trigger needs a mod.
