This is an older Stealth model safe that has been discontinued. These Stealth gun lockers are made using 18 gauge steel and utilizing two keys to open, these lockers will store up to 3 rifles or shotguns without attachments in a straight line fashion. If your rifle or shotgun has an extended magazine or scope you can store it sideways. Please note, the locker can store only 1 rifle or shotgun sideways and up to 3 vertically in the included foam gun rack. The keys are the long skeleton style which are proven to be far more secure than circular tubular locks. Each lock has it's own unique key way and you will need both keys to open the locker. The Stealth Gun Locker has two 5/8" bolts at each key way for a total of 4 bolts. This locker uses an internal hinge and opens up to 90° making them great for the closet. The Stealth gun locker has 4 bolt down holes in the back and none on the bottom.
