Thanks for the heads up. I've never tried the AG ones, having gotten reliable function in all of my rifles with most of the GI ones of various nationality. When I one of mine becomes too worn, it gets tossed. When testing some "new" ones, I mark the good ones. Honestly, they are cheap enough on the second hand market, not sure why one would need new ones. Just order several surplus ones, and you're likely to get mostly good. DO stay away from any un-marked Parkerized ones. Those tended to come on Greek HXP ammo, and are of dubious reliability.
