I'm no expert on AR15 rifles but am looking at a friends Stag15 and the rear sight is almost all the way cranked right to make up for what looks to be a misalignment issue. We've done a little reading on AR15.com and from what it appears there is no remedy to this problem as the pins @ the front end are gonna line the block up rock solid and the rear where the bbl tightens into the action is 'pinned' on top.
Is there room for adjustment somehow or should he just leave it be. Mostly a cosmetic issue really, only bugs him now that I mentioned it:evil:
I can't see there isn't a way to remedy it though...
Advice?

My Stag model 1 has the rear sight drifted to the right pretty far on the removable carry handle. I've still got lots of room to drift it to the right still, but it's not smack dam in the middle like it is on my fixed carry handle AR15.

It looks like this so it's not bad at all ---> [....0..]

I posted about it on AR15.com and also asked an AR expert from the TSE. The consensus is that it really doesn’t matter and can happen on the carry handle models when the "within spec" numbers start to stack up.

In my specific rifles instance; the carry handle, although rock solid, hangs about a couple thousands of an inch of to the left of the flat top meaning my upper rail and FSB are bang on spec. but my carry handle is a bit off (perhaps to much material relieved on the inside of right rail grabbers (name?).

No biggie, it's zeroed and I've still got room for lots of windage left and right.

My guess is that the FSB is bang on and the barrel is also adjusted properly but the "room to move" is built into the carry handle sight. Does he have any windage in the rear sight or is it litteraly "all the way"?

is the rear sight tightened?
when I got my Stag.. the rear sight fell off while I was handling it... just look to see if it was mounted correctly. is it one of these?

Get a barrel nut wrench and tweek the barrel a bit, there might be enough play to straighten the sight & still allow the bolt to function without binding on the gas tube.
 
IIRC, there was another Stag upper found where the indexing pin seems to have been drilled slightly out of spec.

Alternately:

Just put the FSB under your foot, or clamp it in a big vice, and pull with all your might until the sights are perfectly aligned.

Yeah... ummm... don’t do this.

Since you don't know what the problem is; it would seem like a bad idea to try and solve it.

Putting a barrel wrench on the rifle without being a qualified armorer, or AR builder, would be as brilliant as home dentistry.

I'm betting beltfed knows what he's doing; I don't and it dosent sound like you do either.

If it's a big concern just send it back to ArmsEast. Try to do this BEFORE you void your lifetime warrantee, not after. :redface:

Actually, if you have a barrel wrench and a PROPER reciever wrench, the AR is possibly one of the easiest guns in the world to rebarrel. If you don't have a proper reciever block, don't try it. And if its brand new as you seem to suggest, thats why god invented warrentee's, and ArmsEast is supposed to be good to deal with (I haven't, hope to in the future)
 
possibly a canted front sight base ?

I read of a couple of instances of stags having canted front sights.. As suggested above, just contact arms east and i am sure all will be well..
 
Sorry, :redface: I assumed this was a build question (using proper tools)..... Didn't think they were coming out manufactured all messed up....

Ditto to sending it back where purchased, if you didn't piece this together, you shouldn't be left to tidy things up.
 
My LMT 10.5" upper looks like this:

[.0....]

But I've already got it perfect so I don't want to mess with it... doesn't bother me as it is accurate.
 
I think the advice received seems reasonable, the rear sight may not zero at dead centre. However, if your friend has any concerns please ask him to contact me at the address below.

Thanks,

Contact Arms East.

I examined another Stag Arms rifle that had this issue, and AE corrected it IMMEDIATELY.

Don't start taking parts off, or bending things. Get ahold of Arms East and get it fixed right.

Thanks everybody. :) I bet him I'd be able to get some good answers here within 24 hours, you haven't disappointed! (Pint of Guiness for me!) Thanks again.
Now, back to playing with that Ottawa Citizen database :evil:
