With the AW ban sunset looming on the horizon, and depending on the ban actually sunsetting (which depends on how well we communicate our wishes to Congress), I have been kicking around the idea of how to go about having a rifle with pre-ban features that I can legally possess and use in the meantime. I know that I want a 14.5 inch Bushmaster M4 with a Vortex flash hider permanently attached and collapsible stock.
Can I avoid the ban by assembling it around one of those 10 round internal magazine lowers, while keeping a stripped Bushmaster lower in reserve for the sunset? Or, could I also build it as a straight pull bolt action on a regular post ban receiver by say, cutting the gas tube in half and welding it shut? I would lean toward the latter for the fact that a gas tube could be replaced much easier and cheaper than a lower. If not, does anyone else have any ideas?
I know that both of these ideas are sacriligious as they do dishonour to the beauty of the AR design - the ability to accept standard capacity detachable magazines and fire them as soon as the rifle reloads itself, all in one nice ergonomic package, but I want to have everything together ready to be assembled, in the event that time gets to be of the essence and avoid paying higher prices for pre-ban parts after the sunset, and still be able to legally use it now. Thanks in advance.
