Brownells Offers Scope Mounting Video
Brownells has a helpful Instructional Video showing how to attach a one-piece scope mount and dove-tailed rings on a rifle. Brownells tech David Bennetts shows how to degrease the parts properly, torque the screws correctly, and adjust scope placement for proper eye relief.
In the video, Bennetts installs a conventional ring set with dove-tail front ring + windage adjustable rear ring. We actually prefer a non-adjustable double-dovetail installation. Double dovetails provide a rock-solid, low-profile installation that works well on hunting rifles–you never have to worry about the rear ring working loose. Burris makes double-dovetail sets with Signature polymer inserts. Offset (assymetric) inserts allow “pre-loaded” windage correction in the rings themselves. Hence you don’t need an old-fashioned rear ring that slides from side to side for gross windage adjustments.
This video is just an introductory clip. It does not cover ring lapping or more sophisticated methods of reticle alignment. We recommend, when mounting the scope, to use multiple bubble levels and a plumb line to ensure that the scope’s cross-hairs are truly aligned properly. With some commercial scopes, unfortunately, the reticle is canted up to 3° internally relative to the turrets. With such a scope, you CAN set the reticle square, but then your turrets will be canted relative to the receiver. That creates issues when shooting at long range. Accordingly, if your scope has a badly canted reticle, you should send it back to the manufacture for warranty repair.
You might mention that dovetail rings – which must have some tiny amount of clearance between ring and base to assemble – will never be as rigid as a clamp-type mount. If a solid arrangement is a goal, you are better served with one of the Weaver mounts or their clones.
weavers blow though.Dual dovetails have never failed me. even with big magnums.
