I have used this pack twice (still in excellent condition) and am going to stick with a traditional bag. Color is coyote brown and it includes the shotgun scabbard.

Their website says $389 Retail for the pack and $40 for shotgun scabbard. I will sell this one for $250 + half of actual shipping. Paypal (discreet), MO or personal check (when it clears).
