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

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.

I do have mine and thanks for the offer. The UM recoil lug isn’t coming out without damaging the stock. I heated and used vice grips and ended up chipping the lug . ZERO movement in any vector. Tapping it side to side doesn’t budge it. The factory lug came out easily with moderate pressure. I used a more accurate dial micrometer and it does appear to be a touch proud at about .095. More test with puddy confirm that it’s contacting as well.

Dang haha.

Dang haha.

Yeah I think she’s with the stock until the stock is broken in half. I think my jokes on the main thread may have gotten me in trouble. Real surprised to not have heard from them. They were real quick with comms until recently.

Sorry I'm late, I don't like it! You don't see a comb shape like this on any military sniper rifle. Recoil will bring the shooter's face/check off the stock, nothing for quick follow-up shots. Good for the recoil sensitive though.

This might have been addressed in the intervening 5 pages ... but there's at least one rifle that has been used by a serving military that has a negative comb ...
