TK Cornerstone Rotary Safety for Ruger PC Carbin

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


The TANDEMKROSS family of Cornerstones just got bigger! Introducing the Cornerstone Rotary Safety for Ruger® PC Carbine™.


While cross bolt (push-button) safeties are fairly easy to use, they can still be improved. One crucial flaw with the traditional cross-bolt design is that the only person who can easily, visually confirm the SAFE or FIRE state of the firearm is the user. Another weakness to be improved is that regardless of whether you are left- or right-handed, you have to break your grip at least once when toggling between SAFE or FIRE.


Our ambidextrous safety solves both of these issues with a single upgrade! The Cornerstone’s levers on both sides of the firearm visibly show a clear difference between SAFE and FIRE to the user and those standing nearby. You can also switch between SAFE and FIRE while maintaining a firm grip on the firearm with your shooting hand!


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


Cornerstone Safeties are already major upgrades for the Ruger® Mark IV™ and Mark IV™ 22/45™. The Cornerstone Rotary Safety was previously only available with the Manticore Trigger Assembly for Ruger® 10/22®, but can now be yours for your Ruger® PC Carbine™ or PC Charger™!
