I believed he did, that particular T91 gas block was modified for pencil profile barrel which is 0.625"(15.875mm) diameter on gas block landing area. Wolf A1 is 18mm, the barrel has to trim down to fit.
No range report yet, I will follow up with him and report back here.
Just confirm with Ricky,
His gunsmith cut the Wolf A1 front sight block out, remove the barrel and lathe it down to fit the T91 front sight block.
Didn't mention what type of tooling was used to remove and remount the barrel.
Awaiting for his range report...
Well if it runs the way it's supposed to I'd lay hands on every gas block I could get, and that smith will be in high demand to turn barrels down. The nut can be taken off with a spanner nut wrench and if the right size was on hand even torqued (I would assume using standard AR torque). There are wrenches like this out there and they ain't cheap - this example is for a Bell 407 helo and runs $65.00 before shipping.
