Pretty interesting that you used a FAL gas block. Did you use the FAL gas piston, or use the original piston? How and to what size did you drill the piston opening? 14 mm I'm guessing???
Any problems with the gas leaking around the barrel after the block was mounted since it isn't a tight fit?
Any other info would greatly be appreciated since I'm in the process of using a FAL sight/gas block to build a VERY short pistol.
Thanks.
