Yes I have got another sr in .177 but the prosport was sent back to AA for it's 3rd time 3wks ago come Friday, so with a bit of luck they will have sorted out the cocking link pin, twangy low powered spring , the correct piston weight fitted and maybe then I will contact UK Neil for the muzzle weight if all is well.
Still good shooting rested or not( beats me even with the sr)
