Hey guys,

Has anyone ever thought of making an AR upper in 5.7 x 28mm with a 30rd or 40rd mag. I think it would make an awesome addition to the AR series. What do you guys think.

Why would you want to do that? The 5.7x28 having on a slightly smaller base diameter would not give you any real increase in capacity over 5.56x45. It's a lot more expensive to shoot then 5.56 It does not perform as well as the 5.56x45. What would you use an AR in 5.7x28 for that you couldn't do as well or better with a 5.56x45 AR.

There was one actually worked on - and pictures were posted about a year ago - it never went anywhere.

On my site, the FN Forum - someone just mentioned that another company will be exhibiting such an item at the Shotshow!
