...another direction I went was more for elr 22 stuff. This pic is WITHOUT egw 20moa base but instead a BKL adjustable pellet gun scope mount. Since it lifts the rear ring portion up when adjusting the base itself (BKL 120moa adjustable 30mm base w/ 11mm dovetail) but leaves the front as a fulcrum, I am able to clear BOTH the barrel and bolt w/no issue. The base was a little over $100 and has been an affordable upgrade providing max internal come-ups alond with entire hold range. Happy camper here.
