Well, this 12.7 faxon build is getting frustrating. I have tried 2 0.750 gas blocks, one of them a BCM, and neither one fits, both "seem" too small. Apparently the nitriding process on this barrel has thickened the journal > 0.750. I tried heating the GB and no help. Then chilling the barrel and heating the GB, and I got one to slide partially on but it immediately became stuck, naturally out of position, and I cannot get it off.
I am used to chilling the barrel and/or heating the upper for the BCM uppers, but never have I had this kind of trouble with the gas block.
Heating both did not loosen up the gb... now trying to freeze them both.
If I have to take this to a GS to fix that's going to jump my costs, delay my build, and raise my ire.
Yeeeeesh.
I am certainly thinking faxon has major QC issues in this setup.
I've done 2 other faxon builds and did not have any gb trouble, actually, no troubles at all, with them.
This one is different.
