Everytime I pick one up in the gunshop, show, or range, the diameter is the same size in the dual flip up aperature.

Just wondering. It's one of those factoids you never pick up on unless you're told or you ask. I'd like to know for zeroing...and if it's feasable to install a different aperature, like an A2....

Thanks,

H

on my colt slabside upper it has the two aperatures that are the same size but there is a "L" aper. which is slightly taller.


i use the shorter on on that upper.

What's the 'range' difference between them? 0-200 yards and 2-XXX yards?

I wonder if you could put an A2 aperature back there....?

Yes, you can install a A2 aperture. I've done it. BSW

I use an A2. Quick upgrade for the A1 system. Better sight picture.

Would use the "same plane" A2 if they wern't so expensive.

That's what I wanted to hear - thanks. I too like the larger aperature. But I very rarely shoot past 200 yards......I live in Maine. So a rugged A1 upper design just....makes sense.

With the exception of my SP-1, which I force myself to leave stock, all of my A1 uppers use the A2 aperatures.

The A1 sight system is set up so that when the unmarked aperture is BZO @ 250m, the L aperture is zeroed at 375m.
