This 24DL combo has impressed me. Action snaps open and close as crisply and solidly as some bespoke British doubles I've messed with at the local Cabela's Gun Library. Eyes are not good enough to shoot with the receiver sights but with the inexpensive Bushnell Sportview, the .22WRM barrel has made some 50 yd groups that equal those made with a CZ 452 and high mag/dollar scope.
