Art, I agree about "critical", however if the nut is not sufficiently tight as stated by the person posing the question, the flash hider has some play. And since the front sight is mounted on the flash hider, the front sight then would show that play to a greater amount because of its height above the bore line. Significant -maybe not. But why allow it if it can be rectified with little effort?

Years ago I was assembling an M14 with SAI receiver and parts kit from Israel. Thought I had the castle nut tight but after a few rounds the zero shifted much lower. There were bullet strikes inside the top of the flash hider. This was before I got a flash hider alignment gauge. The castle nut does need to be tight.

If a castle nut wrench is available, it should be able to tighten to the next spot. Haven't ever run into one that couldn't snug up. Even if it's necessary to move the nut back and forth a couple of times, it should be able to seat snugged.
Even if it needs to be backed off one tooth, there should be no wobble.

Thanks for the good inputs. Fortunately I remembered I had another FH purchased years ago and forgotten about. With it the castle nut times perfectly.

I have a USGI nut wrench and could probably crank the first FH a tick more but that is now unnecessary and I am somewhat concerned about damaging the threads on the barrel.

Next time I am out parts shopping I will pick up another nut and see how it times. If not better than what I have I can do the wet/dry sandpaper on a flat surface and see what happens.

It seems to me that someone once mentioned using a #2 pencil as an alignment checker. Anyone aware of that?

Pencil will work if you don't have an alignment tool handy. Just look for equal clearance on all sides.

Finally took the Fulton B/R with Dupage parts kit to the range. Works great. The stock came with the kit and has a fairly tight lock-up. Mostly Winchester parts. Nice well used look to it.

The target with the rifle is my first 5 rounds from 25 yards after getting a zero. I threw one unfortunately.

The other target was at 100 yards. After the first shot I adjusted the elevation and all were hits on the bull. Notice the close string from left to right in the xring area. Turns out the front sight had worked loose after I got a shot in the dead center.

Plain Winchester white box 7.62 NATO ammo.

With a few tweaks this will be a great shooter.

Hope to try it at 600 yards next week using the iron sights.
