Re: Burris Signature Series Scope Rings
I use them and as long as you are willing to carefully set them in the proper rotation they work superbly. The only thing I have actually used them on is lower recoiling target rifles. Some people have claimed that they hold the scope tighter than regular rings and actually work excellently with heavy recoiling rifles.
They appear solid and seem to hold zero well after being adjusted.
With respect to getting slope on the scope in order to be able to obtain a longer range Zero, that is the actual reason I use them on my rifle.
The method I use to get as much zero adjustment as possible is to center the scope crosshairs horizontally and bottom out the vertical adjustment. Then I mount it the scope and rings on the rifle and adjust the offset inserts to give me a 100 yard zero (if possible). This gives me all the the vertical adjustment that the scope is capable of giving. Depending upon the particular rifle and scope combination you can gain up to 20 moa of vertical adjustment. If you use the Burris rings in conjunction with a 20 moa base, you can get a substantial amount of long range usability. If you do such a combination, know that you will need a serious amount of vertical adjustment on the scope to be able to get any closer range zero at all.
