Picked it up last saturday after the "11" day wait. Knoxx SpecOps showed up today, bought a sling, and picked up a rail from work. Top barrel and stock is my hunting/clays setup. Bottom is for HD and zombie invasion. Rail fits perfectly! no modification needed, just screwed out the little screws on the receiver and screwed in the new ones. Now all I need is a few recommendation for optics. Preferably open red-dots.
