[ARCHIVED THREAD] - ARMS #40: Peeps don't have same POI

Posted: 5/5/2003 11:46:33 PM EDT

The large peep and small peep on my two ARMS #40s shoot to distinctly different points of impact. After sighting in with the small peep, 1 1/4 inch low at 25 yards, I switch to the large peep. With very careful centering, it hits about 3 inches lower! This is the case with both my rifles and sights.

Anyone else have this experience? As I recall, my detachable carryhandle sight shot virtually identically with the large and small peep.

That's how it's supposed to work, the peep centers are at different heights. The large peep is for close range, the small is for distance. Sight it in again at 25 or so but with the large one.

Yup, that's how it works. There is probably also a slight sideways shift as well.

Ashley Express makes a same plane aperture that won't change POI when switching back and forth.

Does anyone make a sight leaf with different elevation on small and large holes, and the sideways shift on the screw compensated for?

The close range aperture is 2 MOA lower than the long distance aperture. Ashley makes a same plane rear sight which can be swapped out with your dual plane if you like.

I dont understand...

ALL AR15 sights have different POI for use at 50-200 (large) and 300 (small)

ALL AR15 sights have the offset small hole to compensate for the threads.

What is the problem here?

Devl,

I did not know that. Sorry.

So what is the best method of sighting in? Do you sight in with the small aperture or large, and at what distance?

I've been on this site for over a year, and I somehow missed that rather important fact.

Thanks! Just what I needed to know.

Once that is done, what range is the small peep sighted in for?

300m, approximately. Barrel length and load selection will obviously affect your zero.
