03-A3 rear sight adjustment

dodgeman · 10-12-2009, 05:54 PM

How do you adjust the rear sight of a 03-A3 for elevation. The windage is easy as it has a knob that moves in distanct clicks. For elevation, the peep sight appears to move up and down a stair type setup and is held down by a small screw. How do you change this without a small screw driver handy or am I just looking at the thing wrong?

It's held by friction. Just slide it..

So do I just loosen the little screw that holds the peep sight down and it will slide back and forth?

Don't touch the screw.. Just push the sight up or down the ramp. The screw is just there to hold the spring tension onto the grooves that hold the sight..

It'll be snug and a little difficult to push, but it's supposed to be that way so it doesn't move because of recoil.

O.K. that got me going, it does move pretty hard. As you look at the sight from the back of the rifle, do you use the right front part of the sight to line up the yardage on or the mark on the left side to line up the yardage? I've shot a few hundred rounds through the rifle and had pretty good look just leaving it all the way forward, but at three hundrad yards it shoots a little low.

The same side that lines up with the numbers, but remember that those are suggestions.. I have Carbines which one will shoot dead nuts at 100 and the next will do the same at the marking for 250..

That happens in the 03A3 too.That was why they had the 5 different front sight heights. It could be fine tuned...but the soldier usually didnt have the spare parts or the time to target his rifle to the degree to determine what sight would be best. With the carbine, well like ;aper says, it's just a guide.
