You may want to try Impact Guns in Ogden. They have about the best selection around. Unless you are avoiding a paper trail and looking for the face to face? I see a lot of ARs in the tribune try looking there or build it yourself. Diane at Tight Group Enterprises in West Jordan will take really good care of you with RRA she also has lots of 30 rounders for cheap and lots o ammo!
P.S. Moved to TEXAS and its much better down here!
