what is the torque?

13 ft. pounds. Hope that helps ya.

It's 13-15 inch pounds. 13 ft. lbs will strip those little bolts in a heartbeat.

Mike of oregon recomends 2 to 3 ft-lbs which = 24-36 in-lbs. I used to torque mine to 17 - 24 in-lbs, but it caused the gass block to slip, and gauled my gas port bushing. Makes it hard to remove, and swap out. If you don't have a torque wrench, gap gasblock halves evenly all the way around, and the same feel tight, but not real tight on all 4 screws.

Hmm, 30 inch pounds was enough to strip one of those bolts on my mini-30. Best bet would probably be to use no more than 24-25 inch pounds and use a little loc-tite on them to keep them from coming loose.

Edin, thats a good point. I always use loctite blue so they won't work loose.

More often than striped threads is a stripped head. The allen wrenchs do not last long. The edges of the hex become worn, and will slip, and strip the head. It aircraft, I have worn out as many as 6 new allen wrenches in 1 day. In the allen wrench edges become worn looking, do not use it. You can grind them down past the worn area, debur the bottom sharp edge, and reuse them.

Cajungeo,

I can't believe I never thought of grinding down Allen
wrenches!!!

Here's another idea: find a star drive bit that closely but tightly matches the Allen recess in the screw. With the screw OUT of the gun, and securely held in a vise, align the points of the star bit
with the angles (not the flats) of the Allen screw and tap it home.
Done right, this practically eliminates the problem of stripping.
