Yea, you should. The BATF has prosecuted people for MALFUNCTIONING FAL’s and only backed off when a FAL expert disassembled the weapon under question ON CAMERA and showed them that the firing pin had actually broken.
I think I have a HTS set lying around that I will give you, if I can find them and if you want them. Is it inch or metric?
Freep mail me with your address and the details.
BTW, has the supply of 7.62 NATO gotten any better?
PS I make custom high accuracy heavy barrels for a FAL. Let me know if you ever want one.
