I’ve noticed that when the rear sight is turned down to bottom out at 6/3 , the frame of the sight twists slightly to the left. Any way to keep it perfectly straight?
Has anyone run across this.
Stag15 Model 1, 2 months new.
Is there any way you could post photos? Would probably help with a diagnosis.
Check this sight out see if it gives you some ideas.

I think this is what you are talking about?
Exactly. However, should this be found on a new rifle?
Thats a highpower fix for competition its probably not the best thing in a serious combat rifle. But if the stag is your range toy sure it would be worth a try IMHO.
It does happen to new rifles it will not seriously affect sighting for the most part.
Thanks for the input by all. Great info found in this forum. Glad to be here.
High power competitors take there Iron sight very seriously and do everything under the sun to improve the accuracy of there Iron sights.
To give you an Idea how seriously check out the rear and front sight dail gauge checkers .http://www.ray-vin.com/
This is not unusual. Both my Colts as well as my Bushmaster do it, as do many others. Plus I know from past dialogs that it is a non-issue.
There is a spring in there that keeps that tension, if I recall correctly; it’s done on purpose for repeatability, being easier to keep it consistently pushed to one side than centered.
Yes, I did notice the spring tension. Makes sense. Thanks.
Over analysis can be dangerous.
yep… I have an LMT buis. does the same thing too.
Every AR I’ve ever owned has been that way to varying degrees, regardless of brand.
Hard core service rifle competitors go beyond the shim; they have the sight base fitted with 2 vertical pins that keep the sight base from rotating, and tracking perfectly straight vertically as it moves. Check out White Oak. Had it done to my Colt Hbar. Done not for looks, but for precise repeatability when adjusting over various distances, wind conditions. Over kill for a weapon where iron sights are backup to RDS or scope, in my humble opinion. Not overkill if irons are all you use.

This movement is normal. Because a spring loaded detent keeps constant pressure on the sight assy, the sight is contained in a consistent position. If your anal it will irk you, but in no way effects function, unless your shooting in rifle matches. While in the Marines, most of the rifles in my armory had some degree of movement in the rear sight. Marines still managed to qualify on the rifle range with no problems attributed to the rear sight.
