Are you using the set screw that came with it? Loctite the set screw.


And yes, sometimes they come loose even with loctite. They are still the best sight for the 10/22.

I had used blue loctite on the front sight hex screw and thought I had it tightened good but it came loose when I had to pound out the bolt pin that was painted.  I took out the hex screw and drilled a dimple in the base of the dovetail with the front sight in position.  It gave the hex screw something to seat in and prevent the front sight from moving.  A little blue loctite on the hex screw again, retightened and no problems since.

I would think Red loctite in the dovetail should hold it too.

Hello Group; The dovetail on the barrel and the sight should get a coating of locktite, the set screw also and should be torqued to spec. DO NOT GET ANY on the detent for the front sight, I would remove the front sight and the detent & spring during this operation to be sure it does not take much and the detent will be frozen with no good way to repair. This only an observation of what I have seen and how I make the repair. The sights that have been installed in this manner will give good service. If you want another type get Lyman globe target front and rear, or a Williams rear and the Lyman front globe. The choice is yours but in each case one must be carefull during the install and use the tools properly to get the best from the sight no matter what choice you make. Keep Them in the black, Pappy

My front (tech sights) sight was sloppy in the factory dovetail.  A hammer/punch on the edges bent them down a little and a hammer and center punch on the base (it's called stippling) roughed up the surface and raised up little ridges around the dimples.  That made the tech sight much tighter in the dovetail and then locktite on the threads of the set screw (I used blue, too).

The purpose of the Tech Sights is to give you a GI rifle type sight picture and to make sight adjustments easy and repeatable.  There are other peep sights but I don't know of any for the same money with the same features.

I've installed 2 sets of Tech Sights on 10/22's. The first would fall completely through the dovetail, the second had to be stoned to fit at all. The first fell off the rifle twice at an AS after being blue loctited. It was red loctited and has stayed on for over 2,000 rds since w/ no problem.

I have no experience with Williams 10/22 sights. I've just put Tech-Sights on an SKS and now the Williams' that I took off of are it for sale cheap.

Man, that is some sorry machining on that front dovetail. I really gotta wonder what these Tech Sights are truly worth if the front sight falls out or slides out that easily. I mean seriously. Sounds like a defective product to me.

Thanks for your advice. Williams FP sights for Ruger 10/22  have roughly the same features, for example adjustable windage and elevation, but arent "GI" in appearance.

Eric

It's not that they're adjustable, they're "click" adjustable.  O0

Good luck, Sir.

When I installed my front TechSight, last spring, I pushed it a little too far, that did not help, tightened the set screw and sighted-in. So far, so good. Shortly thereafter attented my second AS shoot. About half way through my groups fell apart. Left dejected. Next day went went to range. Bad shooting. Then I noticed my front sight was very loose.
This is what I did:
Peened the front sight base. Built up the bottom of the front sight w/ epox. Next day, uniformed epox w/ file,,,checked for fit, looked gtg, used Loctite on bases & bottom of set screw hole,,,pushed into position w/ sight-pusher. Seems to have worked.

I'm not so certain it's a tech-sight problem... It could be a ruger problem. (wallyworld 22in.)
I had to drift mine in, I then made the mistake of only blue-locktiting the set screw.
It lasted about 500 rounds before sliding off. I've since used blue locktite on the whole base and it's been good for about 2500 rounds.

Back to my origional point.  Even the factory sight on my ruger was not a good fit.  It was crooked when I bought it(I figured I was swithching it anyway, so I didn't care too much)

A note about Walmart-(I don't mean to bash them)-They have the buying power to have stuff specifically made to their specifications.  Which tend to be the cheapest possible.  They are quantity people, not quallity. (I know several people who have worked for companies contracting merchandise for Walmart.)  Yes, some of their stuff is made in the U.S.A.

But once you work out the kinks.  You're set.  I would stick with the Tech Sights.

Hello Group; Another thought one should remember is you should degrease with a high grade solvent like naptha or MEK the area prior to using the locktite the dovetail and the set scerw,  You just need to be smarter than the tools your working with, Tighten the screws up!! dimples inside the dovetail will help!!peening the dove tail area on the barrel will work but remember folks the front sight base is aluminum!!!!!! The use of any loctight product is highly recomended to solve the dovetail fitting issue, also you do not need 24 hours of wait time for loctite 20 min and it is done. Go to the range and quit  :'( PAPPY
Which has greater value?...... Ammo will get you through times of no money better than money will get you through times of no ammo..

Aftermath makes a good point. I'm sure this isn't the first time some of us have had to deal w/ fitting or re-fitting a part. But it seems it might be someting to be aware of w/ this particular combination. Prior to fitting the tech sight I shot the 10/22 very little . Now it gets to the range regularly. Another point, keep an eye on the action screw on the 10/22, it likes to work loose.

Solder has to be hot enough to melt (no big deal with the soldering gun/iron) but in order to make the solder stick to the front sight or the base they also have to be heated by the solder gun enough to about the melting point of the solder.  Unless you have one heck of a soldering gun it'll be awful tough to get those big chunks of metal that hot.

And tightened it good. So tight, it pushed up on the front of the dovetail and made a very slight crack.


This is what I did to install my front sight, except I didn't bother with the loctite.  Been a few thousand rounds down the barrel since then and no problems.  Mechanical force is all you need to solve any problem.

OK, everybody sit down....after a couple of dropoffs (yes, it fell off) using blue Loctite and as much elbow grease as I dared, I found a good 25m zero by keeping the rear site centered and moving the front site, then ran a bead of super glue around the dovetail. Has anyone passed out yet?

Yeah, I know it's a bit sloppy and irreversible, but it's kind of a special purpose rifle, and I've had no problems in the last three Appleseeds.

Just a thought for those seeking quick, low tech fixes!

They make something even stronger than red loctite, green is even tougher. Maybe the front sight needs green Permatex loctite?


Careful--Green Locktite is designed to seep into already assembled components--It can spread into areas where you don't want it to go

After hearing all these problems I was concerned what I would run into when I put my tech sights on. But it went great with the front sight being a nice snug fit, taps from a small hammer to install. When I switched to my M1 it was nice having a familiar look.
