My max-flo's adjustment cap's screw hole is stripped. the hex screw, if i just tap the reg onto my hand, falls right out. i didn't over tighten, i just noticed a tiny bit of thread bite (much less than i normally use to secure the cap) and then it spun freely. when i took out the screw, i actually pulled off a small coil of metal

and i'm not going to run around with a semi loose adjustment cap. yeah... NO! what should i do?
i actually like the tough look of the max-flo, it works great, and it's anno matches the rest of the gun. can't really re-tap it larger as there isn't much metal down there to work with.
don't want to get another reg really. but if i must i must. suggestions? anyone selling a blue vertical max-flo adjustment cap?
