    Default SOT Question: M16 Barrel Length and Form 4s

    Does it matter to the ATF if the upper currently on a registered M16 lower is a different length than what's listed on the form? When buying or selling an M16, do you make sure the barrel length and F4 or F3 match? Basically I want to know if I should have an upper with the appropriate barrel length available should I ever go to sell the gun. Thanks in advance.

    I think it is. I remember(IIRC) my dealer stating I had to mark down the correct length barrel length
    even though it was a full-auto. I could be wrong, it was some time ago.

    Thanks Bogey. Guess the best option is to make sure an upper of the correct length is with it. Cheap enough, all things considered.
