There are many stereotypes about various people, but Jews are frugal. But stupid they are not! If they are throwing away Orlites and replacing them with USGI's, believe me, you don't want their old Orlites either. Most of the Orlites I have seen were well used, and many, about 1/3 had cracked feedlips. Basically, poor range mags. I would use them for nothing else. Certainly not plugged into my "when things go bump in the night" AR. Why waste the money on them? How much are they now? $7, $8? I would rather one new, GOOD, USGI than two or three Orlites.
No, the Israelis never used Thermolds.
The Canadians did, and went to USGI.
If you simply must buy a non USGI mag, I can highly recommend the steel SA-80 mags. CMMG no longer has the black steel ones I got (and was happy with), but Dillon
www.bluepress.com still has some gray ones. But why buy those for $20, and have to change the follower, when you can get USGI mags that are ready to go for less?
