The Hi-Point 995 carbine is not legal to purchase in all states of America. It's legal in most states where it's considered a pistol-chambered carbine, but in some states, such as Connecticut and New York, it's classified as an assault weapon and, therefore, not legal.
The Hi-Point carbine was originally designed to circumvent the 1994 Federal Assault Weapons Ban by offering some features of an assault rifle without falling into a prohibited category. Since the Federal ban expired in 2004, various states have adopted their own definition of what constitutes as assault weapon. In some cases, firearms may be modified to comply with state legislation. For instance, in California, a Hi-Point carbine may be fitted with a bullet button to semi-permanently attach the magazine and render it legal.
