I have a Remington 1100 semi-auto 12GA with 4+1 capacity, standard stock.

 

Considering NJ allows maximum capacity of six, can I add a 2 round mag extension to it? Or is that considered 6+1 and not legal?

 

On a unrelated note, I want to put a stand off / breacher similar to this PK90 suggested (they are for threaded barrel), but I would like one that's a clamp-on. Anyone sells those?

6+1 is ok

Rem sells a screw in choke with the breacher.

I think Radek is using a barrel which will be cut down to a cylinder bore, so he needs something which will clamp/set screw/weld on, threading it, would defeat the purpose of using that barrel

Yeah, the barrel for Rem 1100 you donated to me! Thanks again!

 

I have cut it down to 18.5" for HD. Don't plan to thread just to install a choke ...
