I bought half dozen have not used them yet .just came yesterday.For AR .556. Anyone used them?
I have only used the Mexmags.
i got 5 with a rifle. don't know if they have been modified or not but they don't have the last round hold open funtion. might just be these. i'd rather have metal anyway.
I will give mine a try monday not off work until then.
Finally used 3 of the Hexmags all worked great last round was hold open in all three. Happy so far.
Hexmags are on sale at gunmagwarehouse for about $7 each in six packs.
