I was surprised to hear someone asking for a higher rear sight. I frequently see guns in need of a lower rear sight. I guess we're talking about two different things here but this phenomenon has become a major frustration for me. Here's what I see:
The carbine won't sight in until the front sight is dialed up so high that it's sticking up above the front sight base's protective ears. It's sitting there waiting to rip flesh or hook on something and get bent. This is always on a flattop carbine, and the front sights are either standard units or on some cases flip ups-- but usually standard ones. I never get to do a really in-depth exam of the gun, but my suspects are:
-Manufacturers who don't know that there are two different heights of front sight base, and/or they get them mixed up (short handguard guns should get the higher one).
-Some flattop uppers have a rail that is higher and some are lower.
-Some BUIS are higher or lower and incompatible with certain setups.
I sometimes am able to cure half the problem using the Bushmaster extra-high front sight post-- at least this gets the flange down far enough to contact the detent, and the threaded part is in deep enough that the post doesn't wobble side to side too bad-- but the post tip still sticks up beyond the protective ears.
Anybody got the real answer on this?
