I saw this post on arfcom and wanted to share with all of you. Previously the BATFE held that if you converted your pistol into a rifle (adding a buttstock and a barrel 16" or longer) you couldn't convert it back. I, and many others, thought that was pretty [silly] interpretation of the law. Well now, they are reversing this stance and are allowing people to convert back to a pistol.

As we all know, most of the pistols that people convert to a carbine are considered "assault pistols" under Hawaii law, so how does this affect us? There are a few pistols that don't fall under that classification such as the Glock and 1911 with a carbine kit from from Mechtech Systems. I'm sure there are others.

I'll reiterate that I am not a lawyer, but I believe these will be legal under both State and Federal laws. If you want a lengthy read, you can find the BATFE's ruling below.
