So of my three micrometers not a one has a scale that goes to the end. That’s a tricky spot for such a precise measurement. How did you measure? I used a square but mm was the smallest measurement. It’s too hard to eyeball. It’s right at about 2.4-2.6mm which 2.4 would be in spec but it’s real close that’s for sure. I’m not pulling that thing without damaging the lug. Did you use some leather or how did you do it exactly? Mine is welded tight.

Caliper

I don’t know how I’m not figuring this out but I can’t figure out how to get any caliper’s I have into there and flush without ending up measuring with an angle.

Use the bottom of the caliper. When you open the jaws a small portion should protrude from the "handle" read the measurement from normal location.

lol, duh lightbulb just finally lit up

End of your caliper

Yup somehow never used that feature and it just clicked. .0925, so that would explain the smashed play dough with it being so close.

Maybe I’m being too picky at this point. Anyone else have a change in stock barrel separation when torquing down or loosening the front action screw? It was bad enough before I removed the pressure points seen in the prior photos that a finger stuck in the gap to feel the movement would be pinched to the point of pain when loosening the front action screw. Now it’s subtly visible and can be felt but couldn’t pinch. The gap is tightening when I loosen the front action screw. Which leads me to believe my contact point is forward of the front action screw.

Are you using the long screw in the front instead of the back? haha.

You should NOT see the barreled action rising as you tighten and lowering as you loosen, the only time I've seen that happen is when the recoil lug slot in the action isn't directly over the lug.

Ha nope but after my caliper brain fart it doesn’t hurt to ask. I’m definitely over the lug I can feel it set in and the multiple play dough test I’ve done confirm it. This is driving me crazy. With the super tight tolerance with the caliper and play dough results it’s possible I guess that I’m still hitting the lug.

A 4th example here…

It should be sunk down but you should not see a large gap increasing in the front as you tourque. More dremmel work needed?

Also. Do you have your factory recoil lug to try? Pull the UM unit out by heating and tapping side to side and then fine point tipped good vice grips. Tap in the factory lug and try it.

If you don’t have the factory I can send you one of mine I have a few laying around.
