How to adjust A2

Featured Replies

This is gonna seem like a dumb question to most of you but here goes:

 

I was loaned one of this tools to adjust an A2 from sight. It had 4 prongs on one side and 5 on the other. I looked at my sight and it appeared the 4 prong was the end I needed but it wouldn't work for me. I eventually went back and forth trying both ends but it seemed I could not push down and twist as all. I watched at least a half dozen videos on how to use them and it looks so damn easy yet I couldn't figure it out.

You can use a bullet point if you want. Just depress the pin that's pushing up on the sight and then turn accordingly. I'll try to find a picture

See the pin in front? The other prongs should line up with the indentations in the sight.

As mentioned, most use the bullet tip. I found that most of those tools are made cheap and will not fit various configurations. If you can find a good one, you're lucky. If the manufacturer gives you one with their sight, most will work. But third party, forget about it.

You see the button in the front. Press that bad boy down and twist the front sight post.

Thanks guys. I can push the button down with a 5.56 round but can't get good purchase on the post to twist it.

Lol. Needle nose pliers

With the bullet point pushing down the spring loaded plunger, twist the front sight by turning it clockwise or counterclockwise. Ive been doing this for almost 50 years.

I seen enough to get the jist lol

You should not need pliers to do this. I've been adjusting sights on AR/M16/M4 rifles since 1968. I've never had to use pliers which will undoubtedly scar your front sight.

 

Use the round to push the sight CW or CCW via the notches in the base of the blade. Google AR or M16 operators manual which will illustrate what I'm saying. Don't Bubba your front sight with pliers.

Use a pencil eraser.

 

Jez... Paul you are "Old School"   That's what I do when I can't get a tool to fit.

 

Jab a pencil eraser on the sight. Push the plunger down with a bullet tip, And go at it!

 

Remember you move the front sight OPPOSITE the way you want the point of impact to move.

I've had the same problem. Have been trying to get my rifle sighted in. Left to right I'm pretty good. Have to bring it up about 2 inches or so.

 

Thanks for the pencil eraser idea. I'm going to try that!

Found the tool that works perfectly on my A2 sight at Shooters yesterday! Was able to walk my pattern right to the target ...at 25 yards anyway. I'll have to wait til I can get on an outdoor range to see about zeroing in at further distances.
