This electronic gun rack is designed to hold up to two long guns, a rifle and a shotgun, and can be wired to a switch for quick release. Each has a manual backup handcuff key lock. Features cloth padding on inside of locking arms to prevent scuffs/damage to firearms. 
 
We have a couple different production types of these in stock. Yours may vary slightly from photos, but will functionally be the same.
