I know the EB22 is pretty close to the legal limit as it is but what potential does it have? It seems to have a pretty good trigger as it is but the mechanism is crude and begs for a bit of attention with the springs and a bit of a polish. Are there any upgrades available? Caliber conversions, valves, bolts, hammers and actions? All I can find is an adapter for a silencer which looks terrible (personal taste). I would like to smooth it out and fit a decent set of sights. Anyone got any advice?
