I've just discovered an airsporter variant that has eluded me for years...
.. a properly accurate one
Just been playing with my recently acquired RB2 .22 (from a very nice chap on the BBS, who I met at Mick's springer bash). It quite likes hobbies (around 1/2" at 20 yards) but really like JSB exacts (1/4" at 20 yards).
Running at 10.8 FP, all I've done is shave 30g off the piston and fitted a new seal. It's still quite lively to shoot, but can't complain about the accuracy. And I know it's all modern and new fangled, but it looks lovery too...
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
