Brownells told me they had 36 on order that were to be delivered on 6/23 with 14 of those already spoken for. Is this just my run of bad luck or has anyone else experienced the same? Monday Burris and Mid South are getting a not so nice phone call.
This is information that was passed on to me by a good shooting buddy in Canada.. It's may have something to do with your problem of not get inserts.. The info was spot on...
Here's part of it.


Was talking with shooting buddy Cliff tonight about his new F-Class rifle chambered for the 6.5/284. He had been testing some loads earlier in the day and was surprised he only had 32 minutes of elevation available after getting his 100 yard zero. Normally that would not be too far out of line except his Remington action was equipped with a Farrell 20 m.o.a. base along with Burris Signature Zee rings and +/- inserts that should have given him another 20 m.o.a. for a total of an additional 40 minutes over and above the 45 minutes of elevation available in his Nightforce NXS scope.

This made no sense and I accused him of having a brain fart which caused him to reverse the Burris inserts when he mounted the scope. He of course denied this. We discussed other possible causes but always came back to the probability that it was an insert problem. We removed the scope, checked the inserts and found he had used them correctly as per their +/- markings.

Before we remounted the scope I used his digital calipers to check the thickness of the inserts and found the problem. Surprisingly three of the four inserts were marked incorrectly. Two of the (+) inserts should have been marked (-) and one of the (-) inserts was actually a (+). I suspect that many hundreds, if not thousands, of improperly marked inserts have been packaged by Burris waiting quietly to drive unsuspecting shooters crazy. Cliff will be talking to Burris about this tomorrow.

I have used both the 1 and 30mm Burris Signature Zee rings many times without difficulty and will continue to use them however I will be checking the inserts with my calipers before mounting the scope. I have not yet checked the thickness of the 1 inserts but a rough measurement of the 30mm inserts indicates the following;

30mm (+10) Insert thickness should measure 0.116 to 0.118

30mm (-10) Insert thickness should measure 0.096 to 0.098

Measurements were taken across the center of the insert. If anyone has been puzzled by the results after using these Burris inserts I suggest you check them very carefully.

Good luck.

That's interesting. The last set i put on my 243. I had to put a.0010 shim between the one piece base and the right side of the front ring to get it close to POA /POI. I don't how many rounds i put down the barrel on that go around. Sounds to me Burris needs a wake up call.
