Level-Level-Level works because the scope is leveled to your receiver, not to the top of a scope base Level-Level-Level gives you the means to level your scope perfectly in only minutes Level your scope as you mount it on your rifle The magnetic base in the rifle level bridges the bolt raceway, allowing you to position your rifle perfectly level Then level the scope, tighten the rings, and the job is done Works with practically any bolt-action rifle Adaptable to other designs
