That's it, in the lower right corner of the back "U"?
Two other ready service mags - these have been loaded for almost a year, IIRC. These ride in the CZ supplied twin 30 round mag pouch in the Scorpion case, get banged around in there a lot.



Understand, I'm NOT disagreeing with you on the obvious, that your mags are cracking. I just personally haven't seen it yet. As you can see, those are 2014 marked mags, as well. Have you had any difficulty replacing them through CZ-USA? And no, I really don't have any info about any plans to make changes to magazines or polymer formula.

I'm jealous of your 2014 mags.  Cz has been great, just getting annoying though not having a good set of mags yet.

I haven't had any issues from mine. Got a couple 30 rounders That have been loaded 6 months.  That said, there is obviously a problem. The mags seem to be a weak point, they should ditch the plastic an either upgrade the polymer or go with metal mags.

I was thinking about these cracks. Could it be from putting the mag into the gun? Slapping it in? Not like loading a magazine once. Prolonged feeding it into the gun could cause the overall structure to weaken?

Mine hoard of cracked mags weren't slapped.  You should be able to pop them, the magazine spring takes the brunt, and, it's a military arm.

yeah, but the military trains you to load a mag into your weapon with an open bolt.  so if you slap the mag in on an open bolt, the mag release and mag cutout take the brunt of the abuse.  what they don't train you to do is load on a closed bolt because there is the possibility of slamming the feed lips into the bottom of the bolt causing deformation.  remedial action (SPORTS) Slap magazine, Pull charging handle, Observe chamber, Release charging handle, Tap forward assist, Squeeze trigger...doesn't do any damage to the mag because it's already inserted into the mag well (almost 0 distance travel for mag)

This is one of the 20 round magazines that came with my Scorpion. It has been used as a range magazine since then. It has been loaded mainly with 5 rounds at a time, but has been loaded with 15-20 rounds at a time as well. This is the magazine you see in most of my Scorpion videos. Here is how it looks today, as of about 20 minutes ago. ;)







It has been there, done that, been slapped in, pushed in, dropped at least twice i can think of, etc. I don't think it's the slapping in or wear from use that causes the cracks.

The mag spring couldn't take the brunt of the force. You have an external hard shell (the magazine) and the spring is internal. If I am slamming my mag, and it stops, the spring is going to continue some of tht upward momentum. Especially if it is not fully loaded.

I watched all of your scorpion vids on utube last night. Great videos by the way. Pretty funny at times. Would be nice to see your sbr to compare the difference between using the cheek rest and a stock.

Anyways. What I did notice is that every time you loaded a mag, it was on an open bolt (as it should be) and that was the point I was making

The carry mags have all been loaded against a closed bolt - I carry the Scorpion "cruiser ready" with an empty chamber, loaded magazine. Yes, it is quite legal to carry the Scorp down here in AZ. :) But thanks for pointing that out, and yes, I do like to amuse while educating/showing off. ;) As for SBR...not likely, too expensive. About the only thing I would consider doing now would be replacing the Thordsen's with a Shockwave Blade and folding joint, for easier carry in the bags I have ATM. I like loading with open bolt on video to show off the bolt release...the bolt release I hope someone redesigns into the BREN...hint hint, Manticore?

I have to say when I was training with rifles in the military, (M-14, BTW), I cannot remember ever loading to an open bolt. Always lock, load, aim, fire. BUT, that was a few years ago, so I might be mistaken.
