I just bought a Burris Signature with posi-lock from a guy at a gun show. It was a used scope with no box or instructions. From what I read, if I unlock(unscrew) sight in then lock (screw in),the scope is less likely to lose its zeroed setting. Am I right about this and if so does anyone have experience with this feature? The scope I bought looked extremely clear and crisp. I know its not a Zeiss,Kahles etc. But I got an extra gun I can put it on and thought I got a bargain. Let me know if you know anything about this posi-lock feature.

I believe you are correct. It should have a little tool with it, probably nothing more than a small screwdriver(?). You should loosen the small turret at the 8-o-clock position before adjusting windage or elevation turrets. When they are set where you want them, snug that third turret back up. All it really is is an opposing screw to remove any play in the erector assembly. If this is not correct, someone will plumb me up shortly!

I have the posi-lock on my Burris black diamond. It sits on my 300 win mag. One ingaged, it has never moved. Remember that you have to loosen it every time you need to adjust it. Tightening it down will move the POI a little, so make sure you tighten it, shoot it and see where it hits. Then once it is sighted in where you want it, leave it, and it shouldn't move.
You also do not have to use the posi-lock. Springs still put tension like any other scope. wether you use posi-lock or not, you shouldn't have any problems with the scope.
here is the link to the burris explanation. http://www.burrisoptics.com/tech.html
Hope this helps. You could also call Burris and I am sure they would send you the information for the scope for free. Good luck. You picked up a nice scope. Enjoy.

Posi-lok does seem to work as advertised in the scopes I have used. However, in my experience with Burris scopes such equipped, the scope held zero without th eposi-lok engaged just fine.

It does as well on my black diamond with it. Without the posi-lock engaged, the scope acts like a normal scope. The spring still provides tension to hold the adjustments in place. The only time I have ever really used the posi-lock is when I am hunting on horseback where the gun gets bounced around alot. Just extra insurance that the scope will be where it should be when the shot comes.

You are correct, RONK. I have owned 3 scopes with this feature. It is nothing more than a hard stop that locks the erector tube in place in lieu of spring pressure alone. There is only 2 things you need to remember about the Posi-Lok:
1. Don't forget to loosen it before making W/E adjustments.
2. Don't tighten it too much after making adjustments. Just snug is sufficient.
Failing to heed either of these may damage the erector tube.
