A2 carry handle sight - windage adjustment. How much is too much?

[neil0311]

Without more investigation on your part how do you really know if it is the barrel or the upper?
.

All I can do is zero it and see if it’s close to mechanical zero or way off like before.

This is a range toy, so it’s not something I’m depending on for my safety. Next time, I’d get a Colt or a Windham.

I had an all original Colt AR-15 A2 Sporter II Carbine with the same problem

The rear sight unit was at fault, I replaced it and all was in order

Wouldn’t they check that by swapping the carry handle? I guess if there was an obvious cant or other issue with the barrel geometry then they might not even bother.

Did you replace the rear sight assembly or the entire carry handle?

Just the rear sight assembly. It’s a fixed carry handle

Where that aperture sits in relation to the sight tunnel on your handle will not change when the rifle is zeroed just because you changed out the rear sight base for one with a tiny bit of difference in width (allowing for more threads / adjustment to the left).

That rear aperture really should be sitting closer to the middle of the handle tunnel. It's not because something aside of your rear sight assembly is tweaked. (your FSB or how the barrel is clocked in your upper)

That method does not move the FSP or do squat to those pins nor is it intended to.

Don't cherry pick bud. Read the post in its entirety.

It would appear that a clamp on FSB is being manufactured again.

I haven't dealt with DEZ Tactical, but I have had good luck with Fulton Armory.

I did read your post.

I've found FSB taper pins some of the most difficult AR15 pins to remove. The dead blow hammer will make them even more difficult to remove should that ever be required.

That crap is not true and shows you do not understand what that method of adjustment is actually supposed to be doing. And then your post about it spreads the lack of understanding to others here...

Again - That method does not move the front sight base and is not supposed to. Before that thing (the FSB) even thinks about moving the index pin will be broken or serious damage will happen to its slot in the upper (or both).

You’re truly a gem.
