Have a friend that just moved to CT. He's trying to determine if he can take possession of a 11in barreled 7 62x39 CZ Bren 2 chambered in 7.62x39 with a fixed brace (I believe he said OAL falls over the "other" definition for CT). I know it'll be considered a assault weapon so would have to limit mag cap to 10 rounds but I believe since his wife is military he can have him at their house or as long as they attend range together.

Being a multiple NFA stamp collector I'm pretty versed in Ky state and BATF federal laws, but know diddly about CT specific laws and he's not knowledgeable enough to know how to ask these specifics and I don't like him enough to read through multiple pages for him.

Any advice appreciated.

Not an expert on the military thing and how that impacts CT law, however, generally speaking--in addition to the OAL requirement, barrel has to be @ least 12" to be considered an "other."  Pinning the muzzle device on an 11" should get it over that easily.

Like the previous poster indicated under 12 inch barrel means it's a pistol per CT's definitions. Who ever is the owner of the firearm would have to be active duty military or some other exempted class person to bring in a firearm that CT classifies as an assault weapon. CT's AWB considers any post 9/13/94 manufactured semiautomatic detachable magazine pistol with the detachable magazine outside the pistol grip to be an assault weapon (among other things). As the previous poster indicated one would have to pin some kind of muzzle device/extension on the pistol barrel to get it over 12 inches, but then one runs into any OAL or barrel length issues set forth in ATF rules/federal law(s) for "others" or SBR/AOW/tax stamp territory. Also note that CT has a magazine ban. Some of the CT statutes touching on your question follows. One may want to consult a knowledgeable CT firearms lawyer to get legal answers/opinions to your questions.

Sec. 53-202a. Assault weapons: Definitions.
Sec. 53-202c. Possession of assault weapon prohibited. Exemptions. Class D felony.

Sec. 53-202w. Large capacity magazines. Definitions. Sale, transfer or possession prohibited. Exceptions.

His wife should buy all the non-compliant stuff from him, easy fix.
