see my two posts in this thread from yesterday - complete upper with breech block is considered a firearm because it can be fired like a pen gun + many other controlled devices -


What is a Firearm? The ATF Definition
This is from the ATF
Gun Control Act Definitions

Define: Firearm

Defined Under: 18 U.S.C., § 921(a)(3)

This section is intended to provide basic guidance in understanding firearm terminology.

The term “Firearm” means:

Any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive;



B. The frame or receiver of any such weapon;


C. Any firearm muffler or firearm silencer; or

D. Any destructive device.

Firearm Frame or Receiver

That part of a firearm which provides housing for the hammer, bolt or breechblock, and firing mechanism, and which is usually threaded at its forward portion to receive the barrel, is considered a firearm per 27 CFR § 4red with out grip frame , same as pen guns + other controlled items - - see posted bulletin from GCA 68 -

Hi Allen, it definitely shows some hard recoil, broken rear corner and such, but the firing pin retainment area looks to be unaltered? I would have to say it is most likely that the extractor retainers on the breechblock could well have failed from just a lot of use? Nothing lasts forever, and in the case of Lugers, sometimes for just a little bit? Good luck with your "NO GO" gauge and testing, I'm still here if you need any assistance that i might render?.... Best to you, til....lat'r....GT
