    I think I had heard something like this before, and I need some suggestions. I have an ARMS 40L mounted on my SPR Upper. The Sight has to be cranked all the way to the right for it to be sighted in! Is this normal?

Thanks

There seems to be a lot of this you hear about on these threads, I've got 3 diff. ARMS setups, although none are cranked all the way right, they're pretty close too being all the way right!

I don't know why you hear this a lot on these threads?

Good Luck!

This typically means that your barrel assembly is slightly out of alignment with your upper.  It doesn't take much rotation for the front sight block to be off enough to have zeroing problems.  If you have the tools, you can adjust the barrel yourself, or if you have a clamp-on front sight like the PRI, you can adjust it for mechanical zero quite easily.

I have never seen a rear sight from any maker that was not (CENTERED) to the receiver. Troy is 100% correct. The barrel is either not dead nuts to the receiver, or the front sight housing is a little canted, or a combo of  any any or all.

PRI Flip Up!

PRI Flip Up!



95% chance that your PRI front sight needs to be realigned properly.

ZACTLY what I was thinkin...

Same thing happened to me. I have the newer PRI front flip up with the 4 set screws. Just back the screws from the side you want the bullet to move and tighten from the other.
