scope base mounting

DENWA

I have been installing and bore sighting scopes for friends and at gun shows for about 25 years and would like to get the experts' opinion about my method. I clean the base and receiver with denatured alcohol then put a VERY small amount of removeable Loc-tite on the bottom surface of the base before screwing it on. This serves a two-fold purpose: making the base more of a part of the receiver, and forming a water barrier. I live and hunt in South Arkansas, so the water barrier can be important. I have removed some of the bases with the help of my wife's hair dryer and found no damage to the bluing or other finish on the firearms and never had anyone come back with a complaint. So, what do you guys think?

When mounting a scout type scope base in replace of rear sights on a mauser, Should the base be level to the bore?

I'm going to use a LER 2-7x scope and weaver rings that are the same height. I could possibly find some other rings laying around if I need to offset the scope.

But should the base be level and use offset rings or the other way around?

Anyone ever done this?



BTW I'm using a modified B-Square mount that is now rock solid.

I don't know if we are talking about the same thing but If you are mounting the scope on the barrel most likely it will be on a tapered barrel The bore line of sight should be parallel to the scope tube if possible.This would mandate the mount to be thicker on the front end then the back end or if the mount is same thickness then the ring needs to be taller on the front ring then the rear ring .

I think your right. The base should be parallel to the bore.

NO...not always. Please reread what 'perry shooter' wrote.

Example= If you try to mount it parallel to the bore on a tapered barrel and the ring bottoms aren't level w/each other (X axis), the scope with be crimped, bent, and more often than not---uneven pressure will be exerted on the tube adversely affecting adjustments.

If you do make the RING parallel to the CENTER of the bore line, you must carefully lap the rings so you don't exceed proper tension. Better yet use Burris Signature Rings which can solve alot of problems, and provide better adjustment range.

Scout set ups by today intent, and even historical military design on long barrel rifles were not intended for long range usage.
The scopes adjustment range should be enough if the rifle/ammo/shooter are ok.

Perry+++ Going a little further, that's why it's good practice to mount target blocks "at assembly"
