I'm new and learned everything about the M14 right here browsing on this forum. I have a new SAI/Squad rifle that I have taken apart at least 3 times. You know getting comfortable with your rifle stuff and seeing how things work. Anyway, I went out yesterday to break in the barrel and sight this bad boy in. I used the 25 yard targets I found on this forum. Things went well until I tried to align the marks up on the elevation knob to the 250 yard line mark. How do you align this knob without moving the click setting? I'd like to get this aligned before I go back out to the 100 yard and 200 yard line to verify.

I know when some of you guys see that I went through a "barrel break in" procedure you are going to laugh. I had posted about a month ago about "break in" procedures for the M14 and virtually nobody does this with their battle rifle. I was told to go out and shoot that bad boy until your shoulder hurts, then that ought to cover the break in. Well, next time I might follow your advise since this took 4 hours and my arm is tired from cleaning the barrel. Funny thing...as I proceeded through the "break in" process the rifle started to shoot more and more accurate. Ended up shooting through the same hole at 25 yards. I like the rifle just need to get the elevation thing aligned at the moment.

How do you align this knob without moving the click setting?

1. Gently Grab the elevation knob with padded channel locks; loosen center screw.

2. Set the knob to the distance you have just zeroed (say, 100 yrds). Aperture should not move when the screw is loose.

3. Tighten screw. Now just dial your range using the knob tic marks - any reasonable load will be in the black.

P.S. A 25 yrd zero is gonna be pretty close to a 200 yard zero.

You know, the bullet rises after it leaves the barrel, etc, etc, SORRY--BAD JOKE!!

Before you monkey with the knob, count how many clicks down from your sighted position to full bottom.

Then monkey with the knob, and verify after you are done that the same number of clicks up from bottom will put you back on the 2- mark.

Sometimes when you twist the knob, the rear aperture can move. Checking first makes sure you din't accidentally move the aperture while you realign the knob.

That's the problem I had. When I loosened the screw and tried to move the knob, the whole thing moved. I had to start over and re-sight, that's where I am now.

When I turned the knob to the bottom it was difficult to tell the bottom since it keeps clicking after it reaches the bottom. I am thinking of getting out the digital dial calipers and measuring this bad boy's height first, before counting the clicks.

Any idea's?

Right now you're sighted in right?

The screw in the center of the elevation knob is tight right?

Now, count your clicks to bottom out the rear sight, the knob should stop, the aperture won't go any further, it should be pretty obvious when you get there. Write down how many clicks it takes to bottom the aperture out.

Next, loosen the screw in the center of the elevation knob. Turn the elevation knob counterclockwise till you reach the desired hash mark you want to say is your zero. Now, get whatever you wrote your click count on and turn the knob counterclockwise that amount of clicks, no more, no less.

After this, tighten the screw in the center of the elevation knob then count the clicks up to your zero and see if the hash mark you wanted to line up in fact does. If it does, you're done, go celebrate your mastering of the rear sight zero mark alignment. If it doesn't, well, something went wrong and you'll need to do it all over again.

Follow Up

I followed "No Expert" advise and got it right. It was 19 clicks to bottom out. I loosened the screw when it was bottomed out, set the 200 yard line marker, clicked 19 clicks counter clockwise, locked the screw down, then clicked clockwise 19 clicks. Bingo. Oh yeah. 200 yard mark. Thanks for the help.

BTW. Before starting I did use digital dial calipers to measure the height of the rear sight just to make sure in the event I screwed this up. When finished it did measure up. I will verify at the range next time out.

It's easy when you follow good directions. No confusion now.
