Front sight adjustment tool
So I bought one on eBay for $7 (yeah yeah, I know):
((eBay edit))
It says Colt, but also said A2, and it doesn't fit. Is there a specific tool that we need for our stock A2 sights? I noticed that the notches around our post are rounded, while the one I bought are squared, I didn't notice that before I bought it.

The tool should work. I use a very similar one. Sight is designed to adjust with no tools. Tip of a bullet depresses the plunger to allow it to turn. A 5.56mm cartridge, not .22LR.

Maybe it's just me then. Aren't these things made so you don't have to use the tip of a bullet? Or are you still supposed to use a bullet with it? I don't have any 5.56, but I do have 7.62x54, is that too big?

Does the tool have 4 prongs or 5? Our sight post uses a4 prong adjuster. Your tool probably has a 5 prong end and a larger end for the rear sight in the carry handle. I bought a 4 prong tool that fits on my keyring. Now, if I can't find my adjuster I have bigger problems.

Actually it's for both, one has a 4 prong side, the other a 5 prong side, and yes I am using the 4 prong side. But I noticed that the prongs (on both sides) are squared or blocky whereas the notches around the post sight are rounded. How are the prongs on your tool, Chuck?

I have one from Troy that I bought when I got some BUIS from them. It has square prongs just like yours, and the BUIS have rounded holes. I wouldn't worry about it. Just make sure you are applying solid pressure down onto the sight and turn at the same time. It should turn.

Well guys, I kept trying, and from what it looks like is that the prongs are not long enough to depress the button (or whatever) that keeps the post locked in. So I'm just gonna return it. That allied armory key chain looks good, the prongs look long enough to do the trick.

I use this tool from Brownells. Two versions. One has 5 prongs, the other has 4. Round 5 prong M16 front sight posts were removed from military M16 rifles long, long ago and square section 4-prong posts added. Light reflection off the round edges was a problem in sighting.
This shows the 5-prong version that is rarely used any more. 4-prong version looks the same, just less prongs!
078-015-002 is the Brownells part number for the square, 4-prong version. The rear will adjust M16A1 rear sight windage as well as some of the new, no nonsense rear sights on carbines like my pair of LWRC M6.

The prongs should only be flush with the bottom of the flange you push the tool against. I've had UTG and TAPCO and both worked just fine.

Thanks for the info everyone, yeah it doesn't sit flush, i think it may be just a tad wide as well. I'm looking at the UTG on amazon, good price. I think the one I have is made by Redbird. I already contacted the seller from eBay, he has no problem giving me a refund.
