Could you re-phrase this sentence. I'm not sure what you are saying. I wasn't aware that there was a House Bill calling for an extension, nor what the extension is supposed to ban. Thanks.
The way I understand it. The "Assualt Weapons" ban did ban some firearms based on whether or not that had certain cosmetic features, and the bill also banned the production or import of higher capacity magazines for both rifles and handguns (i.e. no more 15 round mags to replace the original 7 round ones for your M-1911). And the way I read this article the new bill would uphold the weapons ban but doesn't mention the magazines.
I think there are two versions of an AW renewal - the Senate version, authored by that paragon of liberty, the dishonorable Senatrix from California, Dianne Feinstein (nee Feinswine),and the House version, authored by that lunatic, Rep. McCarthy (C -NY), which is much more than a mere reauthorization of the current ban - it is one that bans a whole lot more.
There are multiple bills filed to extend to make permanent the ban. Some merely change the expiration date (H.R. 3831), or remove it, without changing the provisions. The worst of them expand the ban(H.R.2038). Mainly in a reduction of the number of features that will get a gun banned, to one. Also via a redefintion of what is a "pistol grip", pretty much extend the ban to any semi-auto with a removable magazine. A sort of "stealth feature" of the bill.
