Tech Sights Owners - Sight Alignment Issues

[Darryl Licht]

I ordered the new rail mounted Tech Sights several months ago for my Ruger 10/22 in preparation for participating in Appleseeds in the future.

After getting a laser bore sight and sighting in my rifle I have found that the rear sight windage is nearly all the way over to the right when on target. This is with my front sight centered per TS instructions.

I know its just a preference, but this sight picture is driving me crazy. Anyone else have this issue with their Tech Sights?

Any suggestions?

I'd verify that the barrel isn't crooked. Sometimes when you pound on it a lot it gets that way.

Does the MK1 eyeball agree with the laser? Pull the barrel and find a steady rest of some kind. Look through the barrel and find a small target at about 100 yards, reflectors work well. Are the Tech sights still all Marty Feldman when on target? It should be really obvious what part of the equation is off.

There aren't that many good 22LR boresights out there, are you using one of them thingies that dangles out the end of the barrel?

I never pounded on the barrel and wouldn't! 30 year old original front sight came off very easy with a punch and 2 fairly easy whacks, and it was well supported on a wood bench.

It's a Laserlyte boresight, I suspected the boresight but when I put it into a rifle that was known to be dead on, the laser co-witnessed with the iron sights on that gun. So my thinking is the boresight is fine.

I am thinking that maybe the front dovetail isn't lined up properly on the barrel. If you know the 10/22 tech sights you know that the front sight is secured to the front dovetail via 2 set screws, one on either side of the dovetail. So my thought is to get the rear sight centered and then I will adjust the front until its lines up with the laser.

Still, if the barrel was a bit lose, it might pop over. I'd check anyway, just for funzies.

Nope, barrel is fully tight and secured to receiver via the barrel block and bolt.

Can't do that. Tech sights rear mounts on the receiver.

Yeah... I noticed that last night. Even though the title of thread says Tech Sights Owners. He must not have them, or doesn't have them on a 10/22.

Nope, barrel is fully tight and secured to receiver via the barrel block and bolt.

Then possibly the top of the 10/22 is not flat and the sights are at a bit of an angle. I'd just recheck all with a bubble level.

One of my 10-22' s with Tech's was so far off that I had to reset the barrel using a level, and a Gunsmither block to secure the barrel. Centered up nicely.

Sorry for my ignorance here, but where would I put the level? I'm assuming gun in vise, but level what to what here?

Also, I thought the 10/22 Gunsmither blocks were to cure barrel droop which would be an elevation adjustment error in my sights and not a windage adjustment... right, or wrong?

PS - asking questions not to be a smart*****, but to gain knowledge!

--- UPDATE ---

I took it all down and loosened the two hex bolts holding the V-Block and was amazed at the amount of play in that design. Never thought it could or would do that with the V-block!

I tightened the V-block just tight enough that I could still rotate the barrel a lil bit from L to R. Then setup the boresight to help me align it from left to right, tightened it all down and now I have rear sight centered L to R! After a little fiddling according to boresight Im on target. Time to go to Steele Peak and confirm!

Thanks everyone for all your help!

[Subotai]

Awesome! I put my level on the top of the rear sight and the front sight.

Just to clarify & comment on your method...

1. That would require a 3 or 4 foot level
2. How would that assist with windage check?
3. Your technique would never work on a Tech Sight or any sight with large hood or side blades as the sight itself is lower and inside of those...

Perhaps you do not own any Tech Sights?

I chucked my leveled fore to aft barreled action up in a padded machine vise, put a level across the ears on the rear ears making sure they were leveled left to right, and put a level on the front of the barrel, on the dovetail to check left to right. When both were level, I locked the barrel down with the Gunsmither block. It worked just fine, owing to the precision of the Tech Sights machining. I own one Tech and two Nodaks, here's the proof...
