Benelli M2 Extension Tube

[45 ACP]

How can I determine the proper length to maximize the extension tube on my M2 18.5" barrel length. :)

Thanks

you can check on midway for the length of the nordic tubes.

guess it depends on how many extra rounds you want.

guys who use their m2's for practical shotgun don't mind the tube being longer than the barrel.

if it's for home defence then someone from the US would be better placed to comment.

I know you can get door breacher flash hiders for some shotties, not sure if the m2 has an aftermarket one.

hope this helps.
