So with the custom bodies made a year or two ago I got one minimag aluminum body and one minimag carbon fiber body. The aluminum body works fine but the carbon fiber body will get the bolt to stick and not go all the way back (usually during RT effect). When it stick, the trigger sear is not extended all the way out back pushing the trigger out. To reset it, I can push the bolt back (very little like 1/16-1/8 inch) and then the trigger rod pops back all the way out against the trigger.

I get the feeling the bolt is rubbing on the body or washer sitting inside the body and I'm wondering if I just shoot the hell out of the gun a few hundred times if that will end up fixing the issue.

Anyone ever have this experience?

Again, with the original stainless body and with the aluminum minimag body both show no issues like this (Aluminum body was made around same time as the carbon body)

X-valve, level 10, AGD ULE rail, AGD double trigger frame (non electric).

PS forgive me for not remember the name of who made the bodies I've been out of the game for over a year.
