Santa Cruz Gunlocks leading the industry in quality and customer service since 1988


By 1990, we were getting daily requests from police departments asking for a larger and more versatile gunlock to secure their patrol rifles and semi-automatic shotguns. Our answer was the SC-1 AR Large Gunlock, which is basically a large pump shotgun lock with an adjustable plate in the bottom of the weapon cavity, which can be moved up, down or in an angle to accommodate a variety of firearms.

We were careful to keep essential components interchangeable with the Model SC-1 pump shotgun lock in order to provide an economical solution to secure a variety of guns. There are other types of manual override keys available for this lock.  A 7/32″ allen key is shipped with each lock to move the adjusting plate up and down or in an angle to cater to a tapering fore stock (Colt AR-15, etc.).

This gun lock is suitable for weapon cavity dimensions:

  • Horizontal: 2 1/2″
  • Vertical Max: 2 5/8″
  • Vertical Min: 2″


Check to see if your local Police Department is using a Santa Cruz Gunlock.

Volume Discounts are Available.  Departments may request a Testing & Evaluation Sample!
