New 6920 Loose Rear Sight

Okay, picked up a new 6920 and during tonight's initial clean, I noticed that my rear sight is loose and tilted to the left. When I crank the elevation all the way up, it become snug. However, once I take it back down to flush, you can easily wiggle the rear sight. What am I missing, here? Never noticed this before on other rifles.

I noticed this on my 6920 when I bought it. Looks kind of weird but it zeroed fine and has been ok ever since at all ranges.

This thread is kind of old so I want to make sure I'm OK. I picked up my 6920 a couple hours ago and just noticed that my sight is cocked to the left as well. This is normal as I understand it?

Thank you.

yea, read that thanks, but just wanted an up to date reality check. A little unsightly but as long as it is normal I'm OK.

Thanks for the quick reply.

Unsightly is when the spring and detent go bone dry or you get a wad of mud in there that cocks it the other way and won't let it return.
OR it sounds like a pice of 75 grit sandpaper working a beer can when you turn the body or knobs.
Then all of a sudden your windage adjustment has gone all to shit, but if you start turning the thumbwheel whatever was jamming it may release leaving you with the sight where it is supposed to be, but the windage off again because you tried to compensate instead of correct

Best bet is to give it a quick twist side to side to see if it returns to position and not hang up while doing other pre-use checks, like looking at the front sight post to see if its been bent or the tip of it is dinked or really any number of prep steps.
Checking to ensure the chamber is empty before heading to the line?
Reach up above the CH and give the sight a quick tweak, since your hand is right there anyway.
Shooting oil in to wet the bolt?
Hit the sight with a quick shot and give it a wiggle.

I bought a milsurp carry handle sight (to chop down for my 6720) and noticed that same 'twist' on the rear sight apparatus. I'm not about looks, but for a sight any play is irksome. I solved it by folding a small piece of aluminum foil a couple of times and wedging it at the base of one side. Now it's 'trued up'. About 500 rnds deep wihout an issue from it.

Why are people obsessing over something that isn't broke?

Because they do not have a clue. That's why they are here.
