Things I liked:duel set of lockdown ring screws really keep the scope from shifting... Very light, but also strong to withstand heavy recoil from magnum springer air rifles. Things I would have changed:Including shims to elevate scope at the rear ring for break barrel air rifles would be nice. Use better steel for the allen head screws. What others should know:Over tightening the ring and base screws can strip the allen hex screw head which appear to be made from soft steel.
Things I liked:Really keeps the scope from shifting. Things I would have changed:Nothing.... What others should know:Works best with the lowest rings you can find... I recommend the B-Square Low Sport Utility Rings, which have a double set of scope lockdown screws.
