Great product - Nordic Components MXT Extension Kit, 12ga

I bought the +4 extension kit and enhanced follower for my Beretta 1301 Comp. With the 24 inch barrel the +4 ends flush with the end of the muzzle. The installation of the kit was very easy. I did not need to use the included spring and cut it to size as the original spring from Beretta works with the +4 without needing to be resized or anything. Use this kit with your stock spring. Get the follower. Its red and easier to see and its larger which will reduce the possibility of the follower tilting/jamming.
