QB - I believe FAC currently has imbel GL receivers in stock. They are cheaper than from the Dealer Warehouse at $200, but are imported by Century whereas TDW's are PAC imported. Some folks don't like having Century's name on their gun and some have argued that it would hurt resale value as folks will think it was built by Century.
Some folks are a bit nervous about using the newer receivers that have the date stamping on the magwell, though, as these were imported under the "for repair or replacement only" clause. It appears that this is only binding to the importer, but with the recent moves by the ATF on kit confiscations, who knows what they'll be after next... In that case, the only people with pre-"repair or replacement" Imbel receivers is Sarco, I believe.
I have a FAL receiver wrench, pin gages and headspace gages if you would like to borrow - I believe we're pretty close by. I don't have a barrel vise, but have been making due with a 1 1/16" wrench opened up a bit on the barrel flats. It's worked fine for barreling so far, but I did round the flats on one barrel trying to remove it from the receiver stub without cutting it first, as I did with my previous two. I wanted an unmarred stub as a "souvenier"... Gonna either need to find someone with a barrel vise, bite the bullet and get one myself, or just give up and cut the stub...
