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!


Are you looking for a way to simplify the install of your Cornerstone? Then you should grab the Gunsmither™ Safety Tool for Ruger® 10/22®!


IMPORTANT COMPATIBILITY NOTE: TANDEMKROSS’s Cornerstone Rotary Safety is only compatible with factory Ruger® 10/22® or 22 Charger™ polymer trigger housings (standard and BX).


Don’t forget, all TANDEMKROSS products are made in the USA and come with a LIFETIME guarantee!

    Excellent Upgrade

    Posted by Mark on 17th Jan 2024

    The Tandemkross rotary safety set for the Ruger 10/22 is a terrific upgrade over the OEM push button safety. Just one flick of the finger and the weapon is safe or ready to fire.

    Cross Fire Safety

    Excellent well made safety upgrade. Installs easily (if you remember 90 degrees is a quarter turn and not a half turn)! Great upgrade to 10/22

    Great product, better service

    Posted by Andrew Taylor on 11th Jan 2024

    Cannot recommend Tandemkross products enough. Their products greatly improved my enjoyment of the Ruger 10/22, so much so that I ordered a few upgrades for my new PC Carbine. 4 of 5 went in without issue thanks to their how-to videos on YouTube, but I botched the safety install, which damaged the safety detent spring to the point of no return. I called them up, and they shipped out 2 replacement springs and plungers, which was unable to find available anywhere else. Safety install went off without a hitch on the 10/22. Great product, even better customer support!

    Cornerstone Rotary Safety

    This safety was so easy to install; I didn t even breakdown the Ruger at all. Pre-assembled the new safety as shown in the superb installation video, aligned everything and pushed! Add the right lever and I was done! BTW, unlike a competing company, TandemKross makes their levers from 7075 aluminum, not a polymer that has had breakage issues! Outstanding product and quality from TandemKross! I really wish I hadn t bought the other guy's safety for my other 10/22 first (and it cost more, too!)

    Rotary safety switch

    Posted by Matt on 1st Oct 2023

    Love it. Will be purchasing another later on for a future build. I only used the right side lever and put a beauty washer on the left side and it looks and works great. I chose the BLACK levers. I would recommend this lever to anyone who is a nut over the greatest 22lr semi auto rifle ever made!!

    Very handy

    Posted by Peter on 25th Sep 2023

    I should mention that I now have four of them installed, and ordered two red and two black. I use the black levers on the right side because I wanted something different. Very well made, thanks.
