Try it with the largest head size ftt's you can get. If you wind out the port restricter screw (with heat to loosen the locktight). it'll be even better & may need a coil or two off or weaker spring but will be easier to cock & shoot. The two o-rings on the roller breach may need replacing if the power drops or it's ever inconsistant. Best airsporter I've ever shot by a long way for accuracy & power.Originally Posted by Jon Budd
.. 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...
