Oop… just the DD bolt switch into “G”
“You have made us for yourself, O Lord, and our heart is restless until it rests in you.” -Augustine
Took the entire DD bolt carrier(when you pulled out the charging handle, whole bolt) into “G”….everything worked.
I think we’re beating a dead horse to satisfy our curiosity for exact cause of malfunction. While second nature to us, it seems swapping bolts is outside OP’s skill level. We narrowed down the issue and isolated it for him, Geissele is aware and offering to help, sounds like case closed for now.
James, it's hard to translate your posts, they look like code on my screen. Dan makes a good point. I had one AR that started with short stroking and extraction issues. The upper was a test bed, so it also had an adjustable gas block.
After a very frustrating series of troubleshooting tests, the following problems were uncovered-
- Gas block adjustment locking spring lost tension leading to the gas block adjustment constantly changing
- Extractor spring failing leading to extraction issues
- Piston rings completely worn
- Gas key leaking where it mates to carrier
- Gat tube worn were it fits in gas key
Each problem had to be identified and repaired individually. Each time one was fixed, the next reared its ugly head at test firing, starting the troubleshooting tree again. While it's possible the extractor spring solved your malfunction, it is cheap insurance to make sure there isn't another problem waiting in the wings.
James, if understand the gobble dee gook your posts show up as on my screen, you did the lock back check using a completely different carrier. What Dan is suggesting is, install the known good bolt (DD?) in the G carrier and perform a lock back check. Dan has made an excellent suggestion. Installing a known good bolt, you can test to see if there is a problem with the gas key of the G carrier.

MistWolf…
I did the final testing by installing DD bolt into “G”…..NO issues / function without any issues.
Yesterday, the “ G” tech guy ordered the RMA and I’m send it out the Geissele today.
Again, thanks for sticking with me
The Geissele replaced the REBCG due to the some tolerance stacking issue between the BCG and the upper. They are shipping my baby “G” back today.
