Harrels AR-15 Tuner on a .22

[Raydee]

I recently picked us a Harrel's tuner for one of my 223 rifles and wondered if anyone used one on a .22? I know he sells a specific clamp on version for the rimfires but since my Ruger Precision is threaded I figured the AR-15 version will work because it has the same threads.

I can't answer directly about theirs, but I make and sell a bunch of adapters for my tuners that allow them to be used on both 1/2-28 and 5/8-24 threads and they work very well. Keep in mind, every joint in the WHOLE system of a rifle, moves at high frequencies. We like to think that because something is tight or well fitted, that it doesn't move. That's not true and you can't make it tight enough to make it true. Every joint WILL move. I recommend a drop of blue or purple loctite be used on the barrel threads that the adapter screws onto, for this reason.

I've posted this before but it's been a while. During one of my tuner vibration analysis tests, I actually unglued a glued and screwed action. Went into town, bought an iron, pulled the screws and the barreled action from the stock. It came out of the stock perfect and after letting it cool, I torqued it back in as a bedded only rifle. What we saw on the oscilloscope and the target, was the gun was now out of tune and vibrating at a substantially different frequency than when glued and screwed. It was only two marks out of tune, in regard to shooting small again but at a completely different node that before, frequency wise. In the end, it shot just as well one way as the other but at a totally different vibrational node. Technically at an anti-node, but that a different subject, for a different thread.

This was not a surprise but proved out a hypothesis that was confirmed by vibration analysis, that tune repeats, over and over with a tuner. One of the keys to using a tuner is to establish how far it is from in tune to completely out of tune. This number is very small and quite linear.

Bottom line is, yes, it works with my tuners and adapters. I see no reason it won't be the same with theirs.

Thanks for the reply and the good information.

Since you already have the tuner and it'll fit both rifles (which you also already have), I can tell you an easy way to find out...

I use one on a .17HMR. Works well. On the .17HMR the nodes are very close, only about 3 graduations apart. Make adjustments in small increments.

I was thinking the same thing, but is there enough adjustment in the Harrels $80 brake/tuner?

I picked an extra one up to try for my .22 and will see if it works.
