TK Cornerstone Rotary Safety for Ruger 10/22

Ambidextrous, rotary safety; right or left hand friendly

Allows for single handed use without having to break grip

Clearly shows safe or fire from either side of the firearm


TANDEMKROSS’s family of Cornerstones is growing! Introducing the Cornerstone Rotary Safety for Ruger® 10/22®.


Cross bolt safeties—otherwise known as push-button safeties—are nothing new and are easy to use. That doesn’t mean they can’t be improved. To activate the factory push-button safety, the operator just pushes the button one direction or the other to toggle between SAFE and FIRE. While not difficult to do, there are two key things that could be improved upon.


Firstly, depending on what side of the firearm you are standing on, the only person who can visually confirm the SAFE or FIRE state of the firearm is the user. Secondly, regardless of whether you are left-handed or right-handed, you must break your grip at least once to bring the firearm from a state of SAFE or FIRE to the other and back.


An ambidextrous rotary safety addresses both of these primary concerns with a single upgrade! A safety selector with levers on both sides of the firearm visibly shows a clear difference between SAFE and FIRE to the user and those standing nearby. The RSOs at your local range and matches are sure to love you for it. Plus, you can now toggle between SAFE and FIRE while maintaining a positive grip on the firearm with your shooting hand; right-handed or left-handed!


Additionally, a toggle-style safety selector reduces the possibility of an accidental button push. Resting your firearm on an uneven surface could potentially switch a cross bolt safety from the intended SAFE or FIRE position to its unintended opposite. A rotary safety reinforces that any change in the firearm’s state must be intentional and thus helps make it safer.


Cornerstone Safeties have been wildly popular for the Ruger® Mark IV™ and Mark IV™ 22/45™ and are now also available for the PC Carbine™ and PC Charger™. The Cornerstone Rotary Safety for Ruger® 10/22® was once only available when installed in the Manticore Trigger Assembly, but it can be yours today!


You and your firearm both deserve an upgrade that makes your life easier. Grab an ambidextrous Cornerstone Rotary Safety for Ruger® 10/22® and make your good gun great!
