Hello fellow CZ 511 owners.
While getting lost in the wonderful world wide web I came across an article regarding a company looking into making some CZ 511 / 581 magazines!
(riflemags.co.uk/blog/new-cz-511-and-cz-581-magazines)
From their site
Update 03/04/2015: We've produced a number of 8 and 10 round prototypes, getting the feed lips perfect for a production version is our current challenge, we are hoping to have them available Q3 2015.
I have no idea when or if they will make it here (Canada).........but I sure hope they do!
