Sight Alignment Epiphany

[jsimmons]

I took off the FSP and installed a Yankee-Hill gasblock/flip-up sight, and was wondering how far off center it was. I was intending on spending the better part of tomorrow's range session adjust the windage, when I had an thought.

I just happened to have a .223 laser bore sighter, so I loaded it up, set my rear sight at 0, loosened the bolts on the gas block, and aimed the rifle at a wall about 20 feet away. I then proceeded to gently tap the front sight tower in the appropriate direction until the sight post was centered on the laser dot. Once that was accomplished, I tightened the bolts up on the gas block, and I was zeroed for windage. Now, any further windage adjustment will be for actual wind and not to compensate for a canted sight tower.

A Sort of associated question - should I blue-loctite those gas block bolts?

I do on the front sights of my Glocks when I switched them out. I dont see why it would hurt. It says 24 hrs curing time.

I made a mistake. Instead of going myself, I had my wife stop at Auto Zone on the way home from work to get me some blue loc-tite, and she came back with a $20 bottle of the stuff.

Now you can do every gun sight in town.

Sounds like a good wife to me. I bought a large bottle also, and now I have it whenever I need it.

As far as your front sight, you should shoot it before you Loc-Tite the bolts. The Bore sight may get it close, but you can't be sure how close until you test fire it.

Now you can do every gun sight in Texas.

Fixed that for you. Doesn't take that much Loctite to hold a screw in...
