Then I could submit the chart to be added to the file. He suggested that I make a chart with all the barrel lengths, over all lengths, and calibers that I owned. Since I was going to travel to a submachinegun match I called the Examiner who oversees my transfers to ask about the change in configuration, barrel lengths and calibers with Colt M16 RR I was planning to take.

Last, does it work the same with registered m16 lowers? Like for example, someone with a registered m16 has the original upper and then also a 10.5 upper they run on it sometimes.would they need to make sure they have a pistol lower for the shorty upper when not attached to the registered gun.because when not in use could the ATF claim you were going to manufacture a SBR with the shorty upper or something?Īgain sorry for the ignorance.is there a good source to read about this subject other then just reading thru the NFA texts. Next question, is there a limit, like could someone with a m11/9 have 5 different uld the ATF try to get you for some BS "intent to manufacture" charge having say a Lage shorty upper with k grip, if it's not attached because you have your original upper on or something like that?

Is this OK because it's not a permanent change or something? Do you always need to make sure to keep your original upper with you to put back to original configuration to match the paperwork if needed? But doesn't the tax stamp paperwork have the gun details like barrel length, caliber, etc, which obviously change depending on the upper. One subject I am a little confused on is changing uppers on registered machine guns.įor example, I know the Lage uppers for m11s are very popular.they even have the max11/15, they have an ATF approval letter for (it changes length, caliber, mag location, ejection location etc.

Forgive my ignorance, I am just getting into the FA game.
