Just bought a Benelli M4 and absolutely LOVE it. One question though... what is the best way to go with respect to extending the magazine (plugging of course for Canada and Open in the US :) )? Have been looking at Carrier Comp and a few others, but am a little confused about how to go about it. Does that crimped end of the current magazine just slide off and replace it with something, or should i just by a full tube?

Thanks!
 
(not a lawyer) Having the extension in Canada may be enough to get you charged with a prohibited device, as I don't think the magazine extension fits the pump benelli shotguns.

It is also illegal per the ATF to have a magazine extension on the m4 unless you replace a TON of components on the benelli with US made components per 922(r).

Yes, many people do it anyways in the US, but it is still illegal unless you jump through all the hoops.
 
Understand the legal risk... not necessarily going to do it. Was simply asking HOW it COULD be done... thanks for the tips though.
 
You would have to find a way to permanently limit to hold only 5 rounds BEFORE entering country.

The faux extension just unscrews like the magazine cap does. You could try and get a +2 extension, and epoxy a cylinder of something (plastic block or something) into the tube so it functions just like the faux extension.

You could TRY and get ahold of a full length magazine tube, but it would need to be permanently limited to 5, or riveted through (not exactly good looking).

If you did that, it would be impossible to get the follower and/or spring out should the gun ever need any maintainance to the magazine tube.


As far as things go here, its best to just leave the fax extension on... It looks different, but IMHO it kind of matches the handguard and pistol grip, and is a little more artfully done.


If you are dead set on getting the look of a full length tube, you could always fill the ribs with epoxy, and then use a high grade epoxy-based paint and paint the whole faux extension black to get a seamless look.

Not a "ton"

Yes, 4 or 5 parts (depending on if the ATF counts the pistons once or twice as parts)

(it has 15 parts according to the 922r "parts Table", assuming you count the pistons as 2 parts. Any imported gun that doesn't meet the sporting purposes has to have no more than 10 imported parts.)
 
This was a very very informative post. I greatly appreciate the input. It absolutely helped in making the decision to just leave it be. ;)

Well.. here's something to help your head explode with regards to 922r...

Some have interpreted the rule(s) inapplicable to Benelli because they hold a "Type 7" FFL...

Here's an bit I lifeted from another source. Take it for what it's worth.

What you were told is true in part, but does not apply to Benellis or HK/FABARM shotguns or many other brands of imported firearms for the following reason. 922r applies to all imported firearms UNLESS the importer also holds a Type 7 FFL (Manufacturing) or better. Because Benelli USA possesses a Type 7 FFL and have for many years, all guns they import are entirely exempt from 922r. Anything Benelli imports under the Benelli USA trade name is exempt from 922r provisions. Imported firearms that are imported by Type 7 licensees are treated exactly the same as if the firearms were manufacturered domestically. This is why it is perfectly legal to add a magazine extension or even a folding stock to a Benelli (unless illegal in your state). This is why Benelli can import/manufacture and sell the Practical model (extended magazine tube) and the M4/M1014 WITH the collapsible stock. HK and their line of FABARM shotguns are another example. HK is a licensed Type 7 manufacturer and can import the FABARM line of shotguns without regard to 922r.

Other imported firearms do not have this exemption because their importers are not also Type 7 FFL holders in the U.S. Type 7 FFLS are expensive and require that firearms actually be manufactured for commercial sale, which is not an inexpensive or hobby endeavor.

Yeah the 922r is a huge cluster **** of different rules, its hard to keep track of it now. I think thats why they are now offering them with the full tubes and tele stocks and such.
 
Wait i might have gotten slightly confused... more so. I thought the "importer" in this scenario was the person going in with the 6NIA... so its the manufacturer thats the importer for the 922r rules?

Apparently only if you have a Class-7 FFL or whatever its called.... clear as mud I spose?
 
Well 922r aside, I see lots of guys running FL tubes on their Benelli's I'm the states and not one has been arrested, charged otherwise molested by LE.
If it is indeed technically illegal noone seems to care or worry about being caught or ratted out by their fellow shooters.
