One of my friends recently stumbled across this website, where the proprietors are looking to introduce a unique and interesting new firearm — a double-GLOCK SBR. The patent pending concept is to shove two plastic wunderguns into the same housing so that if one gun runs dry, you still have a second one at your disposal while you reload the first. I suppose there could be some utility there, but all I could think of was . . .
I do have one question, though.
If you add a stock to a GLOCK, it instantly becomes a “short barreled rifle” and requires registration under the National Firearms Act. If you already have one GLOCK registered as an SBR and you add another one to this contraption, does that second receiver need to be registered, too? I’m not entirely sure myself, but I’m pretty sure the answer is yes.
