The Israeli's are Orlite, pretty similar to that mag, which is a Canadian Thremold.
They are both pretty much crap, in cold weather the bottoms will break on contact with soft ground, and spit the rounds and spring all over the place.
They are cheap is all, I have bought them in lots of 100 for 250$ in the past.
I use metal GI mags with the green follower as my "good" mags.
Also, I'm in Canada, our serial numbers were all comprimised when the CFC's database was stolen by somebody working for the Hell's Angels who worked at the Center, so it doesn't matter.
My vault would take a couple hours to crack, and that would be only if the theif knew what he was doing. Ain't no way it's coming out of the basement now that the house is finished around it.
