I put 140 rounds down range yesterday and I had a blast but encountered a couple of problems.

1. How do you keep the screw (windage side) from coming loose all the time?

2. I had put a new roll pin in, and red loctite, to keep my op-rod guide from moving around but on disassembly I saw that it had moved leaving the piston and op-rod misaligned. I tapped it gently back into place with a brass drift. How do you keep the damn thing from moving around or does it even matter?

3. I had to crank a lot of elevation into the rear sight to get it to sight properly. Is this normal? I've noticed that my USGI glass stock kind of pulls down on the barrel a bit, could this be the culprit?

Jeff, first of all, Fun ain't they:D

1 Try tightening the tension screw on the left side down. It will immobilize the sight, windage wise,but it won't come loose either. The other option is replacing it with USGI bits, but if you don't adjust the windage much, and most don't, set it to center, lock it down. You should make your zero adjustments with the blade anyways.
2 Try a slightly larger diameter pin, sorry, can't help much more there, anyone else?
3 pretty standard actually, both of mine need to be set for about 4-500 meters for a 100 meter zero. The solution is shortening the front blade. Carefull work with a file and a vernier so you know how much your taking off can fix this. Set your sight 8 cliks up from all the way down, shoot, file .01", shoot, and repeat till your down where you want to be.

Hope this helps

You can stake the pin using a center punch, this works and allows you to remove it later. I assume you are using a USGI stock?

Do you mean the op-rod guide pin? - It’s (pin) not coming loose but the guide seems to shift. It does not have any play in it now (guide) but I think I may have gotten the barrel hot enough to loosen the red loctite. I may drill out the guide to take a larger pin as it seems the pin isn't making proper contact with the barrel cut-out and the red loctite seems not to hold up under rapid fire.

Yes, I'm using a USGI stock. It's working very well.
 
Jeffman: You are on the right track, use a larger pin. Some other CGNutters have put a smaller diam pin INTO a larger pin that's securing your op rod guide. See what works for your situation. I buy all my pins from Home Depot....
