QB, I think you need to mention that the "metric" FN's are LH thread
and just myself I would like a referance to the "other" end of the barrel as well, you have posted only muzzle threads. I could use an AR barrel extension thread size ( otherwise I will have to wait for my extension to get here to finish my lathe work)

Thanks
Dan

Hmmm, I have the ar 15 barrel extension size around here somewhere I THINK it is 1"x 16 but I will look it up and get back to you. Also I have the thread size and pitch for FN/FAL's as well. metric and "inch" are the same, the only exception is the isralie "izzy" as most FAL people call them, and they can be chased to a standard metric thread, as no one currently has available receivers in the "correct" thread size (entreprise used to advertise them but I have no experience with them)
