Well after thinking this one through a bit more. I'm not really interested in the M14 aka Norinco versions or a remake of the Fals etc. Also in terms of an AR-10. I have a restricted DPMS LR-308 and I'm very happy with it. Lots of fun, a great rifle even though it's restricted. I don't need another one.
What I'd really like to see and probably isn't in the parameters of your project:
1) bullpup. This takes care of the fugly stock problem although many may no doubt disagree.
2) Ambidextrous charging handle, safety etc.
3) Picatiny flat top rail directly into the receiver. No afterthought stuff. no carry handles
4) Free floated or as close as possible with the piston system
5) I want accuracy. The barrel you picked sounds very good.
6) A Canadian maple leaf tastefully rollmarked on the side.
Basically a Tavor only in .308 and with less to no plastic. Think AR meets Tavor/Type 97 without the flaws.
In truth if the Tavor came with a built in flat top, and the option of a target/varmint barrel that gave .5 moa accuracy. I'd buy one in a heartbeat. These types of rifles are the way of the future. .308 is just a bonus.
