Most of the mags have a series of holes in the back to indicate how many rounds are left in the mag. If you shorten the bottom of the platform leg that goes over these holes by a smidgeon (thats an imperial smidgeon, not a metric smidgeon which will be much too short), then with the platform back in the mag you pop rivet into the 10 round indicator hole. That should give you 5-1/2 rounds. If you use a steel instead of a aluminum rivet, it will take the bluing or park and blend in OK...otherwise just hit an aluminum rivet with a permanent black felt marker.

What I like to do is cut the mag in half at about that same indicater hole, bend new lips to hold the baseplate on, and shorten the spring to about 12 coils. Now you can carry pockets full of useful mags, instead of just a half dozen mags only at 15% capacity. Of course, the 30 rounders are much nicer in photos.

Claven, before you run off for Cuba, you'd better have another look at that 3rd batch of photos you posted on the milsurps...something is askew.

I did some MAG. conversions after the kim & windy ban came into efect.

The MB. CFO. Approved them & took them to Ottawa to the CFO's. Mtg.
A rivet made of the same type of material as the MAG. does qualify as legal.

But the one they most favored was I welded a small tube to the bottom of the follower, put in 5 or 10 rds. Measure for 1/2 a rd. for play. Then cut the tube off at the bottom of the MAG.

For plastic MAGS. epoxy is considered legal on a plastic MAGS.

At least that way you can still take the MAG apart for cleaning. Also if you ever need to replace parts like a spring, no problem.
and it doesn't make your MAG. look like crap.

The WPG. Police were pushing for a full length sleeve welded inside & the bottom of the MAG. welded up! Insane!!!

I wonder what the criminals did??
 
It should be entirely possible to make an adapter that would lock into the magazine housing into which a single stack pistol magazine would latch. This would avoid any issues of magazine thickness. As long as the top round was presented in the correct position at the correct angle, feed should be just fine.
 
for giggles, a Chechen home job.

So was the ruling on the mag housing based on the fact that the serial number is typically found there? So for other designs, it depends on where the serial number is, or does it have to do with where the magazine locks?
 
Who knows? There does not seem to be any consistancy. A Luger receiver is the grip frame, even though the upper receiver assembly can be fired when detached from the "receiver". The receiver of an original AR-10 is the lower, even though the upper receiver is serialed. FN upper receivers are controlled, the lower is not. Maybe the location of the magazine is a factor, as you suggest. I had not considered that before. I suspect that the determination is based on the opinion of the decision makers, on a case by case basis, rather than on any consistant principal.
When you get to lock, stock and barrel muzzleloading firearms, which are required to be registered, the deifintion of what is the receiver gets rather fuzzy and silly.
 
There was a court case in Alberta a decade or so back (crown vs Rogan if I recall) where the judge wrote that the receiver was the tube with the trigger plates. Not sure if that has any weight if one went to court.

You can still slam fire a sten with no magwell, so to call that part the reciever is a bit of a stretch. And my closed bolt sten would certainy function as a hand fed gun with no magwell. The magwell is the most complicated part of a very simple gun. I suspect that is what made someone choose the magwell. Usually the Cdn determination of the registered part of the gun coincides with the US determination. Not in this case.

One could challenge it in court, but is it worth all the $$$ vs a couple of hours work to make a new one?

So, it seems the serial number on 3008s are on the tube. If one made a Sten mag well would that be fine? This is all hypothetical.

I guess this thread has gotten too long. Look back somewhere around page 7.

Yes, you can make your own magwell, as long as it is intended for a semi auto. As to open bolt or closed bolt, the closed bolt has been accepted by the CFC, but the open bolt version has yet to be submitted by someone to find out.
