My recommendation would be to fix it yourself -- those bolts wouldn't cost you more than $5 at the local hardware store, maybe $10 if you ordered through MidwayUSA or Brownell's.

Use feeler gauges to make sure your gas block halves are evenly spaced, then tighten in an X pattern. It's easy to get carried away and tighten one side of the gas block too much, then torque the sh¡t out of the other side trying to make gaps even. Trust me...

Anyone remember the bolt torque settings? 32/inch pds keeps popping up in my mind.

Found my notes:
Gas block screw torque 35 in-lb, The screw is 8-36 (5/16th to 3/8" long) grade 8 cap screws. Hex 9/64 The engineering torque spec for that size screw in stainless steel is 22 inch lbs

Can anyone confirm?

I recall reading on here at one point in time that the recommended torque was 30-36 in-lbs. That's what I torqued mine to, and they're still holding strong.

Oh, and FWIW: #8-36x5/16" Socket Cap Bolt, Alloy Steel, Black Oil Finish - BoltDepot.com. $0.19 each.

EDIT: Sweet Jesus!! Don't order those bolts online -- call Bolt Depot first. They show $13+ just for shipping!
