Found this across the street, Tapco mag test:
Just saw that they are on Special at Wideners too - $8.50 ea
I saved the JG link and was waiting to get paid...of course they stopped running it. Picked up 6 from classic, I think it cost me $8.3/mag after shipping.
“The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles.”
