Besides thinning my current front sight post, does anyone make a thinner front sight post?

Compared to my NM front sight on my scout, the front sight post on my AR-15 Carbine is a lot thicker.

Any suggestions? Or a reliable way to evenly slim down all 4 sides to the front post?

You can use an A1 sight, which are thinner than the A2's. There are also 5 levels of adjustment per revolution as opposed to 4.

I have a post that has a very thin at the top. Wish I could tell you more about it but it was given to me. I'll try to find a link.

Dunno if your post is the same as the one the military uses (or used when I was in the Corps), but if it is, the width of the post spans the width of an average man's shoulders when viewed at 500yrds. When shooting at 500yrds during qual week, the target is virtually unrecognizable aside from a black smudge. However, superimposing the front sight post onto the black smudge and pulling off a clean shot effectively guarantees that you'll hit the black, which is in the shape of an average man's standing frame.

In other words, the post may seem wide, but if it is what we used, it has its use.

Just get a NM front sight post and screw it in.

Glad I asked --

Brownells has it here:

That midway link is pretty good too, I like 1'oclock, 3'oclock and 9'oclock look pretty solid

I got the AR15 National Match front sight -- but its not a perfect square, its slightly elongated and angled.

My question is that I suppose I will have to get the front sight as close as possible with the front sight in the correct position (give or take 360 degrees to keep it facing the right way), and then adjust my rear sight?

The FS post you got is a correct NM. You want the high side facing the rear sight and the sloped angle going down towards the muzzle. You usually want the screwed FS down as far as possible into the hole (while keeping the orientation in the previous comment). This will give you the most elevation range at your rear sight. If you leave the FS post too high you will have to use up a lot of your clicks on the RS just to get zero at 100 yrds. OK to have a high FS post if you never plan to shoot 500 or 600 yrds.

I dont know if I am phrasing this question correctly or not but does anyone know the MOA of these sight posts? 1/4 MOA, 1/2 MOA, 1 MOA, Etc. ??

Thanks in advance
