Pinning Mags

Has been discussed many times, but what the heck:
From a fellow CGNer,
"Using calipers from the lower edge of the mag, you need to be approximately 2 inches down for your centre punch. Pics to follow.
ETA: Here's a pic for you. The top hole is for pinning with USGI green followers. The measurement and second hole is for Magpul enhanced followers. The calipers read 1.925 inches. This measurement is to the CENTRE of the rivet hole. This will give you about 5.5 rounds of movement which will allow your mags to seat on a closed bolt with 5 rounds in them."

I hold the piece of bent flat steel with 2 rivits in the bottom. Far more professional, then the rivit doesn't interfere with the mag going in and out of the mag well. Then you don't end up with multiple holes on the back of the mag.
No, it can't. The riveted plug prevents it from sliding far enough to be removed. And don't waste your time calling the RCMP - "official" Colt 5/20 mags were pinned this way.
In using 2 rivets in the base of the magazine, the flat steel plug is held immobile. When I measured the length of the plug, I placed 5 dummy rds in the mag and secured the mag in the mag well. This gave the perfect length required for the plug. If the laws ever change, it will only cost me $3.00 or so for new baseplates for the mags. Modifying 5/20 mags were even simpler.
Indeed. I countersink them through the first fold with an end mill and install a flat metal rivet. Not alum. Very solid, permanent, flat with the spine and it does not interfere with the magwell.
Look out if you replace the follower with one with a different length tail.
(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.

Okay, I have inserted a rod (4b) as demanded by the above regulation and am holding it in place permanently by rivets, are you suggesting that I am missing something? I can't see a rivet being defined as a rod,plug, sleeve or flange personally.

Some stuff thats been hidden away or lost for a while pre-dates this law. I inherited a bunch of odds and ends and one is a magazine I don't even have the rifle for. Atleast I am looking for a way to make it legal. Am I wrong?
