Scope not parallel to bore

I thought the same about my set of xtr's. Turns out they were off center. A different set of rings was just fine. I've seen this same issue with three other sets of xtr's in the last couple weeks. Might be worth it to really look them hard. Mounted on a one piece base you could see mine were not in alignment. Hope maybe your set is better than mine was. They are going back.

I picked up a kokopelli accurizing kit. I used the alignment rods and played with the configuration of the rings and they would point off in the same direction, no matter the configuration every time. The rings themselves are aligned to each other fine.

I installed the rings on an ar flat top receiver and used the rods. Center rod pointed perfectly down the barrel. This is why I think it's either the base or holes.

Sorry to hear that actually. Hope it is your base then. Kinda sucks when your receiver is drilled wrong. Hope you get it worked out. Good luck.

The cheapest way to fix the problem is to get a set of Burris Signature Pos-Align rings with the concentric inserts. They work very well and are pretty inexpensive. I have used several XTR rings and have never had a problem with them. Do not lap aluminum rings, it will take the hard anodizing off and the rings will leave marks on the scope. Also, make sure you are torquing the ring caps and cross bolts properly or your scope can move in the rings. Burris XTR rings should be torqued to 20-25 inch pounds on the caps and 60-100 inch pounds on the cross bolts. The caps on the Signature rings should also be torqued to 20-25 inch pounds.

Check the mounting holes on the top of the receiver. Take a yard stick and line up the holes and see if they are concentric with the barrel. If they are, its the mount and an easy fix.

Thanks.

While the yardstick will give a pretty good "quick'n dirty" check of the receiver screw holes to get a good, accurate assessment it is going to take some precision measuring. You are talking thousandth's of an inch here.
Example- if the holes are out of axial alignment by one thousandth of an inch at the receiver, 10 inches from the leading hole the error is 10 thousandth's of an inch and it grows exponentially.
If the receiver holes are out of tolerance (which is not uncommon on Remington's) there are a couple of options. If the rifle is new send it back to Remington, if not we can fix it- if the misalignment is small enough the holes can be drilled and tapped for oversize screws. If the misalignment is severe the holes are filled by silver soldering threaded screw stubs in the old holes and redrilling/tapping new holes.
