I think it would be fair to say these air rifles have been seen in a bad light. Mainly power jumping up and down and generally problems with the regulator. The triggers can be poor out of the box but spend 30 mins or so with the adjusters, they come very good indeed. The standard regulator needs putting in the bin !!!!! Buy a Huma approx £95 dead easy to fit no modification needed. Balance that up with your hammer and (polish the hammer spring ends) and your Tsar will be transformed !!!!! Now a very consistent 780fps with JSB Exacts. Mine now is an absolute tack driver, with the original LW stainless match grade barrel. Had the rifle about 4 months now from new, was very near to getting rid of it, well pleased that I persisted with it, and won't be parting with it any time soon.
