3 gun shotgun?

Haha...oh I will be, friend. I'm gonna go deep on this one. Really open up the port...


M3Kers, I ordered a 3 shell extension from TacOrd...any ideas for limiting it? Source for Magpul shotgun stock adapters?

I used a wooden dowel with a washer on the end,works good for me with the +5(I like the look of tube flush to the barrel),also I started with sandpaper,lost patience went to a dremmel,still too slow,broke out the air grinder with a sanding wheel works perfect.
 
MOA precision out of USA sells one.

I emailed them last week...they don't ship to Canada.

+5 eh? Got any pics?

Maybe I missed something, but I don't understand why people are putting mag extensions on shotguns and then plugging them.

To comply with the law which limits semi-auto shotguns to 5 rounds in a magazine tube of what the gun is chambered for. Cost for a +1 and a +5 extension is almost the same...so just personal preference.
 
So, why not build a gun on a 3.5 chamber with a 5 shot tube? Does the math allow more 2-3/4 than a 3” chamber with a 5 shot tube?

Have you ever read the law that specifies the legal ways to restrict capacity of a magazine?

Putting a plastic plug or piece of dowel is insufficient. Any tubular magazine that can have its capacity increased by an attachment is a prohibited device whether it holds 6 or more rounds anyways. You literally cant comply with the law unless you weld the magazine tube screw cap in place, so why bother?

(4) A cartridge magazine described in subsection (1) that has been altered or re-manufactured so that it is not capable of containing more than five or ten cartridges, as the case may be, of the type for which it was originally designed is not a prohibited device as prescribed by that subsection if the modification to the magazine cannot be easily removed and the magazine cannot be easily further altered so that it is so capable of containing more than five or ten cartridges, as the case may be.

(5) For the purposes of subsection (4), altering or re-manufacturing a cartridge magazine includes

(a) the indentation of its casing by forging, casting, swaging or impressing;

(b) in the case of a cartridge magazine with a steel or aluminum casing, the insertion and attachment of a plug, sleeve, rod, pin, flange or similar device, made of steel or aluminum, as the case may be, or of a similar material, to the inner surface of its casing by welding, brazing or any other similar method; or

(c) in the case of a cartridge magazine with a casing made of a material other than steel or aluminum, the attachment of a plug, sleeve, rod, pin, flange or similar device, made of steel or of a material similar to that of the magazine casing, to the inner surface of its casing by welding, brazing or any other similar method or by applying a permanent adhesive substance, such as a cement or an epoxy or other glue.

If the wooden dowel is glued in place; It is legal.

I Run Guns blocks all of their automatic shotguns this way, before they cross the border.

CBSA has no problem with it.

As with many such things, it is important to read the "fine print".

Yes, but again if we follow this to the letter, our rivetted and pinned magazines are prohibited devices. This particular part of the law (methods to limit magazine capacity) does not seem to be adequately defined or perhaps enforced, especially in regards to tubular magazines. And as such:

guys I've figured it out. I'm gonna buy a +30 extension designed for a pump action shotgun and put it on my semi shotgun. Magazine not designed for a semi-auto so I should be good to go according to the law right? ;)

Adequately defined is a repeating problem throughout firearms legislation. Enforcement of such arcane laws - particularly of something as innocuous as magazine capacities - is certainly not something I would encourage. That said, you don't think sections 3(5)(a) and (b) adequately address rivets and pins?
