Looking to buy a few scope levels to attach to scopes I have... they indicate if I am canting the scope/gun which can push bullet off target at longer ranges. Would like to spend enough to get a good product but not spend alot of money....prefer the cheapest product that is good and reliable.gun) Brownells has a few and I am guessing others due too. They will be mounted on Burris C4 scopes in 30 mm and 1" tubes. I do alot of night shooting. Would be neat to get one in the illuminated version like the military gets. Thank you.
