Nikon cantilever mount - Nikon Cantilever Rifle Scope Mount, 30mm

Easy install, performs as advertised. I like the double rings, really holds scope securely while leaving room for a scope level. Cross tightening 2 screwsthe on rear then 2 on front then alternating back to rear & front again a couple turns at a time kept scope from going off level while tightening.fit and Finish was excellent Would highly recommend.
