M1 Scout scope experience

[10x]

I've recently had an unhappy experience with a Burris LER scope.
The background is that I've had a couple of eye operations this year and cannot see well through peep sights anymore. Well, I won't get rid of my father's M1 or my M1. So what to do, mount a scout scope and see how that works. I chose an ultimak mount and found a Burris 2x7 handgun scope on sale with Natchez. It had the posi-lock feature.
I didn't know what that was,but later learned the windage and elevation are not spring loaded. Instead a steel cylinder presses against them locked by a set screw.

The first trial-fire two rounds. 6" high and 4 inches right. Unscrew the set screw and adjust the dials. fire two-no change in point of impact (poi). More adjustment, fire two, no change in poi. Over adjust and bring back the poi changed. Tighten the set screw the poi moved 6"-8" high and 6" to 8" right. After more fooling around with this, I could not get the poi to center or left of center. I sent the scope to Burris. They sent it back saying it now held zero. My issue was inconsistent adjustments.

The set screw was so tight I had to use a large handled screw driver to get enough torque to unscrew it. The entire posi lock assembly unscrewed also. I had to use padded pliers to hold the steel shaft threads while unscrewing the set screw. I sent the scope back to Burris. Burris replaced the posi lock assembly.

Second trial by fire- fire two 6" high and 4 " right. Unscrew the set screw and adjust windage and elevation. Tighten the set screw, no change in poi. Unscrew the set screw, over adjust and bring back, tighten the set screw. Got some movement in the poi. Repeat and try to guess how far the adjustment will move the poi. Sometimes inches, sometimes less. Eventually I got in the poi set and stayed set when the set screw was tightened. I easily kept clip after clip in the ten ring.

I hate this posi lock feature. It adds a cumbersome step to adjustments, leaves windage and elevation imprecise and is very hard to do in the field especially with cold hands.

Complained again to Burris, They said send it back and they will replace the posi lock with a posi skirt. This is a spring loaded system that that allows the shooter to just dial the windage and elevation like a conventional scope and not have to deal with the set screw or steel shaft. I couldn't find anything in Burris' web page or literature that discussed this replacement mechanism. I just hope it gives consistent adjustments.

Burris has been very good about working on this scope I just wish they would exchange it for one without the posi lock. I do like the eye relief, I like the 2x7 capability and I like the "ballistic" reticle with hash marks for longer distances. The handgun or scout scope is a good solution for me to keep shooting the M1.

I will add another comment when I get the scope back and can get to the range.

Burris returned the scope with the posi skirt. I went to the range Saturday. Adjustments work as they should, just like a regular scope. With the scope I am now hitting the X ring consistently.

Cool that they took care of issue. How was experience with customer service folks?

Having worked in the repair department at Burris, I can assure you that the posi-lock feature does have a spring in it. What is most likely happening is you're overtightening the posi-lock. You only need to tighten it until you feel resistance, not crank it down. You'll crush the erector tube that way, and possibly break lenses. You can also just leave the posi-lock in the "unlock" position, it'll work just like the posi-skirt.


Glad they got you taken care of.

Customer service people were great. Knowledgeable and efficient. The posi lock on this scope did not hold zero without tension on the set screw. I just did not like the extra step of the set screw. Anyway, burris fixed the problem.
