I did all the work myself. using an electric drill and a 1/8" titanium drill bit as well as a cresent wrench. it is very easy just drill out the pin, it is made from a soft steel and can easely be drilled out. then use the cresent wrench to twist the FH off just remember to turn it to the right as if you were trying to tighten it as it is reverse threaded.
I plan on switching the factory flash hider and understand the FAL's are compatible, but what about the difference from a 7.62 device to 5.56? I would guess you lose functionality of the 7.62 device on a 5.56? Any thought's or am I stupid?
I plan on replacing the flash hider on my FS2000 with a Vortex flash hider made originally for the MK46 and Para SAW models from Smith Enterprises. The part number is 1040V. It has the 9/16"x24 LH threads and it's made for 5.56x45.
The newest version of the Vortex is made to accept the G6 BFA and the SEI quick-disconnect sound suppressors.
