Cornerstone Rotary Safety for Ruger® PC Carbine™ Installation Instructions
At a Glance:
- 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™!
Make your life easier! Grab an ambidextrous Cornerstone Rotary Safety for Ruger® PC Carbine™ and make your good gun great today!

Excellent Upgrade for the Ruger PC Charger
The Ruger PC Charger crossbolt safety works just fine but I figured it could be better. Tandemkross’ Cornerstone Rotary Safety fits the bill. It greatly improved the functionality of the manual safety as well as the appearance of the PC Charger. I strongly recommend that you closely review the Tandemkross installation video before installing the safety. I had an issue with the safety detent plunger and spring flying off. Not to worry! Tandemkross carries the safety detent plunger and spring. They also sent me the Gunsmithing Safety Tool which is a MUST have! Thanks Tandemkross for your excellent customer support! CLM

Cornerstone Rotary Safety for Ruger® PC Carbine
A game changer for me. I screwed the installation process a littlebit but managed to achieve working condition and man - this is completely new gun. A must have for PC Charger.

PC Charger ambi safety
With the help of the video this was one of easiest upgrades to do. The upgrade is something Ruger should consider as a stock item, replacing the push button safety

Nice accent
The only reason I didn't give 5 stars is that every time you disassemble you have to remove these. Otherwise they are an amazing addition to any firearm. Pay attention to the install video. Otherwise you can and will end up in a pickle.

I got the safety in black. Looks great! If you didn’t know you’d think it was a factory part. This is a simple Install. Watch the video before you disassemble the safety. It comes with a T 10 Allen wrench Add blue Loctite to your list.

Cornerstone Rotary Safety Ruger PC Carbine-Black
Highly recommend this safety over the stock barrel one. Easy install thanks to your Videos. I will also now be putting one on my 10-22 in the future

Cornerstone Rotory Safety for Ruger PC Carbine
Works great. Easy to install but make sure you watch the video instructions in their entirety before beginning. If you do not and the safety detent spring and plunger come out, you will need to the 1022 Safety gunsmithing tool to get it back together.

Cornerstone Rotary Safety for Ruger® PC Carbine
Great upgrade and these will increase speed during barrel starts when the safety must be on. Installation was only a little bit of a pain but the online video really helped.

Rotary Safety
Received my safety pretty fast. It was packaged well. The red looks really good, and the quality of the part is great. Watched the installation video once, and then installed mine. It was a super easy installation on my Ruger PC Charger, and I'm very pleased with it.
