It looks pretty promising. Hornady claims they get 2,700 fps with the 108gr ELD match bullets, having a bc of .536. Ar performance had 20" barrels on sale for $200.00 too, but they are currently sold out. The nice thing about it is availability of components and die sets, plus factory ammo. Maybe it will gain enough popularity to make it worth while, like the 6.5 cm.
