kiwi,....
surprisingly, both of my b3s ( ,22caliber) will stack pellets consistently out to about 15 meters, and will tear one ragged hole at about 10 meters. beyond that the groups open up , but not so much that a rodent ( squirrel ? ) size target cant be hit.
neither was "pellet" picky, however both shot consistently to the left by about 2 to 3 inches. elevation however was spot on.
after running out of windage adjustment, i just did away with the iron sights altogether.
triggerwise,........its a crapshoot. the black one pictured hada horrible, gritty trigger. turned out to be a triigger pin that had walked out of the reciever and machining marks on the sear. both were easy fixes.
costwise, they cant be beat.............and the support, tech info and modifications found online would amaze you
