@Doomguy666:

Then again, our firearms laws are exclusively federal, and do not have to navigate a myriad of state laws as you likely do.

Cases in point: no tax stamp for SBR, SBS or AOW; if a firearm is 660mm (26") OAL with a factory barrel (sawed-off = you are going to jail), it is legally non-restricted, assuming not rimfire or centrefire semi-automatic.

All handguns are limited to 106mm barrels or longer, and a magazine capacity no more than 10.

Semi-automatic centrefire long-guns are limited to magazine capacities of 5 or less, and no less than 18.5" barrel length.

So I can have an 8.5" DA Grizzly 12ga pump shotgun (Google it) legally, yet a KelTec CMR30 can only hold 10, and must have a long barrel and pinned stock. Laws, go fig.
