perminantly blocking mag tubes for a semi shotgun?
- Thread starter greg11
- Start date
I'd play with a sheet metal liner between spring and tube to block the follower. Once you get the right length, you can epoxy it in place, or discretely rivit it in place. Since it's just inside the extention, you'll have no trouble in cleaning the tube.
~ Kinda depends on the make and model of shotgun as to recommendations.
~ Will length of mag spring be maintained or shortened?
~ How permanent is permanent?
~~~~~~~~
~ Weld or braze an extension to the magazine cap.
~ Cross pin through the mag tube.
~ Dimple the mag tube.

Well, there's really no such thing as permanent, when you have tools available.
But, permanent as in, the plug I install cannot be removed without a good 10-15 minutes of work.
I'm thinking that partially filling it with some very hard-setting epoxy should do it, right? I figure all I need is to stand it up and fill it with about a 1/2 inch of the stuff and let it set.
The sheet metal is a good idea, but I'm worried the spring would get hooked up on it.

It needs to be more permanent than an arrowshaft...
The Mossberg 930+2 ext just barely allows a 6th 3" shell to get in...
So I'm thinking a little epoxy poured into the tube should take up enough space to prevent that 6th 3" shell from seating.

I have a +2 on my 930 from S&J and here is what I did:
Bought a heavy duty 1/4" bolt and a 1/2" long nut that threads onto it.
Enlarged the hole at the tip of the extension large enough to fit the bolt, thread the nut through on the inside (a long nut driver helps this process monumentally) begin inserting 12 gauge snap caps (I have 12 of them
) and slowly, begin trimming the bolt down to where you can just get 5x 3" shells in. Once you get the correct length cut, apply non permanent blue locktite and tighten everything down.
Granted, this takes alot of assembly and dis-assembly, but the end result is a rock solid, very reliable and non interfering internally plugged +2 extension. It's not easily reversed, but it is possible given time and effort.
Even without the +2 extension, ghost loading the 930, you can get 8x 2 3/4" into the gun (6 in tube, one on elevator/tray, one in chamber) but I wanted the +2 just because it looks that much better

Strictly speaking, is this legal? I didn't think you could simply use a bolt to block a mag. I thought it had to be welded/brazed, ect ect....I have a +2 on my 930 from S&J and here is what I did:

Again, this is one of those grey areas and Mods, please let me know if this is beyond what they would call "legal"
With that said, I've seen full cap pistol mags blocked with a sheet of plastic glued into the bottom of the follower to little pop rivets that blocks it from going to the full capacity being sold legally out of stores. Therefore I cannot see how different the rules would be when applied to a semi shotgun (someone please correct if wrong)
The bolt is not easily reversed and it requires time, dis-assembly, and some effort to remove. Not that different from pop rivets, modded followers, etc.
You could use permanent red locktite to make it even more difficult (or glue even) but I believe so long as you cannot take it off/disable it within seconds without tools, you should be well within the law... Uh... Right?.
CR,
I am not much of a shotgun guy. Can you explain to my how it is legal to make a shotgun limited to 5 rounds of 3 inch shells when you can put more than 5 x 2 3/4 shells. I thought the "standard" if you will for determining capacity was with 2 3/4 shells. I had not heard of this.

If I recall correctly, the definition is a permanent modification of the magazine to restrict the capacity. The issue is how you permanently modify is not articulated in regulation but controlled by policy. The risk for gun owners is if there is a regulatory decision on how to modify the mags, we might find that most if not all mags in the country is not compliant. So the how is what is at issue. The risk is if the govt makes rules to govern this, we might find we don't like the answer to the question.
If the shotgun is chambered for both 3" and 2.75", capacity is determined using the larger shell. Therefore, if you can block the mag tube to 5.75 shells of 3" (in other words, make the tube as long as possible, but make it unable to hold six 3" shells), it will be legal, and able to hold six 2.75" shells.
You'd be good to go. Also, hypothetically, if the shotgun were able to chamber 2" shells as well, you'd be able to get 8 shells in legally.
I was just confirming this with "Mike" the "technician in Ottawa" I was transferred to when you call the 731-4000 number.
It confirms what both FrankieT and I believe, if the shotgun is designed for 3" and 2 3/4"
"If you can fit 5x 3" rounds into the tube, outside of that, we don't care"
He went on to talk about 40 S&W mags working in 9mm guns etc. as an example of smaller rounds fitting in magazine designed for larger calibers.
"Mike" also confirmed that drilling a hole in the +2 extension adding a bolt and gluing the nut inside the extension is legal.
"Modification to the magazine body is considered more permanent, which is what we look for if we were asked. If it takes tools and effort to remove and not something easily undone, it would be compliant not like something like an inline block where you could dis-assemble and it would fall out. If you drilled a hole in the extension tube and glued the nut on the inside as you described, that is considered a modification to the magazine body. "
For the record, this was technicians name was "Mike from Ottawa" he was very courteous and friendly. I don't know why people don't call the CFP number more often... It's there, we should use it.
I hope that helps answer any of the questions surrounding the blocking of extensions that anyone may have.
Now go forth to Simon at S&J and make your purchases!!

IMHO, this bolt and nut are not sufficient. There should be a weld or similar involved. You need to have to cut or grind something to remove it.
Why take a risk with it?
ps I just read the last post.
I have read this before and wonder...is this written into the law? Can we see this in black and white? It's always nice to have something in your hand other than your d***.
Think the RCMP letter re the 10 round AR15 pistol magazines...that is something people can show the police, on the spot, to explain why they are legal. Remember, the police don't necessarily have a photographic memory of every clause of the convoluted Firearms Act.

I would agree. We need something on paper.
The problem for none Remington owners which can share the 870 and 1187 mag extensions, the semi auto only extension would be considered prohibited until limited permanently.
Good to hear about the bolt being okay.
Realistically speaking, it is more or less the same idea as a rivet, especially if a touch of epoxy was used to make it more perminant.
And like others have said, the real litmus test is when a smokey tries to get that 6th 3" shell in there. If he can't he porbably won't investigate further than asking you to disassemble to make sure you don't have a simple dowel setup.

Hmm. I wonder if a wooden block cut round with a hole saw, with a screw through the end hole to keep the wood block in place, would suffice. I mean considering how easy it is to remove the plug from a tapco sks mag (for cleaningggg!).....
Easily removable? No go. Read the preceding posts.
