barrel length vs gas block location vs port size

[txjm]

What parts should be wet? bolt and barrel extension?

wet: bolt lugs, cam pin area, bolt body inside carrier, a few drops down the carrier key hole. Put a drop in the holes on the side of the carrier. The rails down the carrier bottom and around the key on top.

Basically you could dunk the while bolt carrier group in a quart of oil and that would work fine.

Dont wear a nice shirt when you shoot it. First rounds will blow off any excess.

Sounds to me like it might be trying to unlock too early when the pressure is still too high.

That can be a tough fix
