One of my loaners is a 10/22 compact model, mounted with Tech-Sights.  The mounting screws have been a bit loose in the action from the get-go (none of my other 10/22s have this problem).  I put in some blue goop when it was new, but nonetheless the screws have vibrated loose several times in last couple of years, with the thread locker renewed each time.  This weekend we got to the next logical step, when the forward screw finally stripped out of the action threads and disappeared somewhere on the firing line.  :wb: The rear screw is again loose and probably on the edge of doing the same thing.

It looks like the logical thing to do is to tap out the screw holes to a larger diameter, and change the Tech-Sight mounting screws to match.  Has anyone done this?  What diameter/pitch did you use?  Could you find matching hardware to work with the Tech-Sights?  Any different ideas for a fix?

See Phenry'sreply in this thread.

Good luck
Last evening, it occurred to me that when a defender of Liberty is called home, their load lands upon the shoulders of the defenders left behind. Just as the Founders did their duty for Liberty, every subsequent generation must continue their work lest Liberty perish. As there is no way for the remaining adults to take on the work of those that die, we must pass the ideals and duties on to the children. -PHenery

Eh, JB Weld might be the way to go, since I've got no reason to put anything but the Tech-Sights on this receiver.

Check if the original screws went all the way through the receiver. Usually they stop short a few threads for the last 3 holes and the first hole just about always has a bunch of thread as the receiver is thick at the barrel. So the easy fix is longer screws cut/polish them smooth in the receiver.

If the threads are "kinda" buggered Brownell sells an slightly oversize screw for fixing "kinda" buggered threads.

If the threads are really buggered Brownell sell a tap kit for the next size.

JB Weld has a place... but not this time.

Do you have a link or part number for the Brownell's stuff?  Might be worth a few $ to keep options open. 

I doubt the 'few threads' left would help if they were there - I suspect they were too loose to start with, since I've only had the problem with this one rifle out of four I own.  With luck, that plus wear from vibration might have them in the 'kinda buggered' category.

Here ya go.


If you don't want to buy the tap you can get away without. Take one of the screws dremal a point on it, then cut a groove on one side. Start the modded screw into the hole with plenty of light oil turn eeeeasy about 1/16 to 1/8 turn at a time, back out from time to time and clean the threads. Go slow the steel screw will cut the soft aluminum that Ruger used just fine. Remember --- Slow and easy.

You could try some loctite thread replacer or bearing locker. Use a good release agent on the screw.

Screw is somewhere in the dust on the firing line, so might as well replace it with an up-size.

Pretty easy and common to put a heli-coil in I have one that has held strong for 15 years. http://www.noblefix.com/ you can pick them up at a Napa store or similar.

For the record, I ended up buying and using the Brownell tap & up-size screw set referenced up-thread.  It worked easily and the screws and sights seem to be holding well - though we'll see if I say that after they've been slammed around during a few more 'seeds.  There might have been a cheaper way, but I have a feeling this isn't the last time I'll see this problem  ::) - so a little investment seemed warranted.

I second the JB Weld fix.  Just like PHenry, I had an issue with the rear sight mounting holes stripping out, and I didn't want to pay any extra for oversized screws/taps.  The problem is the extremely fine pitch of the screw, versus the thin aluminum receiver- it is VERY easy to strip the screw holes.  Since this rifle was always going to be a loaner, and always going to have the tech-sight mounted to the rear receiver, I simply coated the screws (lightly) with JB Weld and then slathered a wee bit between the sight and receiver.  To my knowledge, the sight has yet to come loose, after two years of regular use on the AS firing line. 

The next time your screw strips in the receiver (and it will), use JB Weld.  It's permanent, but inexpensive and effective.

my go to for all types of mounts is JB weld quik with no release agent - do it the first time and you will never have loose / stripped issues

less than .25 in materials per rifle and a 15 min job

hot air gun will release the epoxy and it can be rubbed off with wood ( JB weld quik for lower temp release )

The "right way" (proper way) to fix this is to bring them out from that 6-48 size, out to 8-40 size, and alter the rear sight base.

I use red loctite on mine, and it's held up. Of course, I learned the hard way early on, so I probably caught them before they wobbled themselves much.

The JB weld isn't a bad idea, but make sure you understand, it's pretty much permanent.

And, I recommend using a torque screwdriver (or a lot of caution) when tightening those screws. As said, they do tend to strip somewhat from over tightening.
