Bolt buffer for Ruger PC Carbine 9mm
This Buffer is ten times better than the original Buffer, and so is the steel spring retainer. Outstanding products and I am glad to have found your company on Google.

Must Have Upgrade for the Ruger PC Charger
Highly recommend upgrade for the Ruger PC Charger along with the Tandemkross bolt retaining clip. Excellent build quality and easy installation! CLM

Quality product, Top tier customer service!
The build quality of this buffer is vastly superior to another aftermarket buffer which lasted about 600 rounds before breaking. Just at first glance, one can tell the TANDEMKROSS Shock Block Bolt Buffer is of superior construction, with superior materials. That being said, my order was delayed, and the excellent level of customer service I received, while perhaps may be a dying breed, was a pleasant surprise and instilled further confidence in the product I've received. Big thanks to Jeff, and all the other unsung who make these products available with an obvious regard toward the end-user!

If you want the best for your charger this is awesome stuff, add a suppressor and pew pew.
