Oh, Lord - NOW you've asked for it!
Anyhoo, my sample of 1 was using a friend's R8 in .308, and it fed perfectly. The whole concept was foreign to this 'Merican, but seeing as how I was overseas, it seemed to work fine, nonetheless.
I never would have figured one could remove the entire magazine & trigger assy, & have it go back together well, but it certainly did. Very nice trigger, too.
With any luck, that rifle's owner may chime in, by the by....
