I have one and love it and the looks it gets in 3gun and PCC matches is priceless. "That a .22" until the shooting starts.
Fist sized groups at 75yds freehand, will stretch it further soon. Only thing is 16mm grooves and as I wanted peep sites on mine it took some looking, then some fitting but it works amazingly well.
Be aware these are labelled and the same parts as a BRNO but are made by a Czechoslovakian company, called PPK, that bought a bunch of old tooling. Take down like a Browning semi 22 and cleaning a breeze, light as a whisper to carry
