Does anyone know the easiest, legal, way to reduce the capacity of a Nordic shotgun tube, for a Benelli M2, or Versa Max. I want to hold 6 X 2 3/4" shells, and only 5 x 3" shells, in order to meet the legal requirements. Post, or PM. Thanks
Pinning a shotgun tube?
- Thread starter Dick Proenneke

Usually pinning a tube is done by just putting a plastic piece inside the tube between the follower and the cap.
However, I do not know if that is legal for semi auto shotguns.
- maybe if it was permanently mounted to the follower?

I'm pretty sure it has to be a "permanent" modification. I have an older Benelli 121 M1 that needed to have the plug riveted in place. Reason being that it takes very little time to take the mag cap/tube extension off to add/remove the piece that is limiting the mag capacity if it's just floating around in the tube.

Those guys have everything..
I used a plastic spacer in mine from some random plastic tube that I had kicking around. Did a rough calculation of the length based on 5.9 3 inch shells plus some space for the spring to compress and then I trimmed it down till it was good for 5.9 but would not except a 6th 3 inch shell (3" receiver)
Once I had the length figured out I used some hot melt glue and silicone to attach it inside the extension.
If you use a wooden dowel you could screw through the end of the extension into the dowel to secure it and then fill the head of the screw with epoxy or something to make it less removable.

Problem with the +2, is that it only gives you 5 rounds of 2 3/4". You'd have to go to a +3 and then internally obstruct an inch, in order to make it work for 6 rounds, which is the maximum you can hold in a semi-auto shotgun with a 3" chamber. And yes, I do prefer the look of the equal tube lengths.
Use an old aluminium arrow shaft with the head insert cut just above the threads (later mentioned rivet needs a shoulder to bear on) and JB Weld into the shaft. Find and cut proper length of shaft needed for legal capacity. Drill a 3/16" hole in the front center of the mag tube extention if there's not already one there. Use a 3/4" (or longer if required) aluminium pop rivet with a dab of JB Weld on it to secure the arrow shaft inside the Mag tube. Use can also JB Weld a second insert with a rounded off field point to prevent a spring coil from possibly hooking the otherwise open end of the shaft. That will give you a pretty cheap, light and relatively permanent plug...removal requires drilling the head off the rivet.
Me and some other forumites came up with this:
The difference in my method and greg11's was that I used loctite on a nut inside the extension in place of the epoxy.
My research turned up this tidbit in post #13: http://www.canadiangunnutz.com/foru...y-blocking-mag-tubes-for-a-semi-shotgun/page2
Basically, they harder it is to reverse, the less likely you are to be scrutinized.
Good luck!.
I've now gotten 2 requests to explain my Mag Ext. Mod.
I see the 930 is becoming a popular shotgun on the board, as it should be. I think it is an AMAZING firearm for the money. I don't have the funds for an M4 or M2 and, while I don't want to start a Moss./Ben. debate, I personally feel that for my non-military purposes, the 930 is the perfect gun for me. I do wish I had an M4 though (oh, if I ever win the lottery, hahah).
So, behold my insane MS Paint Skillz, and see below. This is how I did my extension.
Get a threaded steel rod from Kent. They're in those yellow bins in the hardware aisles at Kent. There are various diameters and lengths. I brought my mag tube with me so I could choose the right diameter for the hole that's in BBB's tube. The threaded rod doesn't need to be super thick, as there isn't any strain put on in laterally... Buy two nuts for said rod as well (as you can see....). Buy some permapoxy from cantire or wherever....
The spring collapses around the threaded rod as rounds are inserted. My epoxy dries HARD AS A ROCK, so I'm not concerned about the spring digging into it. But if you are, you could put an appropriately sized washer in there (a nickel with a hole drilled directly in the center would be just about perfect for the spring to rest on).
Be careful about where you finally set the nuts. It took some fiddling but you'll "feel" where to put the inside nut. Seat the inside nut just to the point where you can get 95% of that 6th 3" shell in the tube, but WILL NOT SEAT IN THE TUBE. BE WARNED: IF THAT 6TH 3" SHELL CAN SEAT IN THE TUBE, YOU'LL HAVE A PROHIBITED DEVICE. MAKE SURE YOU CANNOT SEAT THE 6TH 3" SHELL!!!!!! This will allow you to get about 6 and a half 2.75" shells in there (6+1+1 Ghost, pretty f**kin awesome). Then saw off the extra length of threaded rod and chuck it or keep it, up to you.
Enjoy your ###y Mossberg.
Mine is my absolute favourite shotty. I'll never sell it.

I would not recommend pinning based on troubles a friend had. Here is what I did.
I permanently fixed a piece of dowel to the end cap. Something small enough that stops shells but allows the spring to extend the full distance.
Then permanent fix the end cap to the tube using epoxy. The thing isn't gonna come apart.
Overall, you won't be able to load past the dowel, but because the spring goes past it reloads will be like butter.
