That's where I bought it :lol:
Since I've already headed down this road, I'll try it out for a month or two while I save up to send it to ADCO. I'll try and keep everyone updated with any leakage.

red... then stake the bolts/srews/whatever you want to call them. good luck.. I personally learned the hard way not to use anything but a pinned front sight. light duty girlfriend rifle or any other for that matter.
just my .2c's
I personally have never got loctite 620 hotter than its ~400 something degree melting point. NOT saying it isn't possible.. I just haven't shot one long enough to get the barrel over 400. Fwiw, the clamp on fsb that failed me wasn't due to loctite... it was due to the inner fender well/exhaust bracket of my GMC.

this is what I use... I was wrong... 650*
OP,
I had a similar situation with a gunshow barrel that had the pins drilled wrong twice. This was discovered after realizing the FSB was canted so far as to make zeroing impossible. After knocking the pins out and making sure the FSB was centered, I drilled straight through, tapped the holes (8-40 IIRC), then installed 4 cap screws cut down so they just touched when tightened down. I should have used set screws for a neater look, but I had the cap screws and it's just a beater frankengun. Total cost was about $1.
FWIW
YMMV
I could be completely wrong (I'm NOT an armorer). I just have never had the red 620 loctite be the weakness for anything I have used it for.
I get it at NAPA.. used it for exhaust fittings which run on LEAN running (read: lots of compression, lots of timing) head/cam LSx's...
Have snapped collector bolts trying to unwind them. Point is, it is permanent.
save the barrel for a trade or your next build and buy a completed barrel. you can never go wrong with extra parts laying around in a time of need
Standard triangle FSBs are pretty easy to mount to a barrel. On the bottom where the gas port drill hole is, above the sling mount,you can tap that and run a set screw right there. For added strength you can drill and tap a set screw through the bayonet mount and dimple the barrel for a very secure install. Use a high temp loctite, they are good up to 650F. This is best accomplished with a drill press, but a vise and a steady hand should also work.
Be prepared to drill the screws and destroy the FSB if you want to replace it, as the high temp stuff is tough to break loose and set screws strip easily.
No way is this gonna be a strong as a pinned mount though.
