One of the things that keeps this from being classed as AOW is the over 26" length. However one of the things that makes a firearm AOW is a smooth bore and concealable. So by that definition if you concealed it in a backpack it might become an AOW and require a tax stamp, I read an ATF opinion that being over 26" does not necessarily mean it can't also be classified as AOW.

By the (lack of) definition for a rifle and shotgun in Texas, there could be other firearms which could be illegal by the same means as a shockwave. An ar pistol is a pistol by federal definition, is there a definition in Texas law for a pistol? Could an especially aggressive DA prosecute for possession of a SBR since it fired rifle caliber rounds and looks like a short rifle, even though federal law says it's a pistol? If you base it only on the round fired and there is no definition of pistol, rifle, or shotgun, a Taurus judge which is definitely a pistol could be classified as a shotgun because it fires a 410 shotgun shell. I say all this not to try to make those guns illegal, more to point out how ambiguity in the law can be ran with and common sense left by the wayside.
