    Quality product, Top tier customer service!

    Posted by JFergel on 24th Jan 2025

    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!

    Was able to get one of these after a 3 month wait in order to be restocked. Good product and easy installation. Enhanced my shooting experience while reducing wear on the receiver

    Shock Block

    Posted by Greg Pettis on 21st Jul 2023

    After installing all the other great [TK] stuff to make a Ruger PC really work well in AMBIDEXTROUS MODE, I wasn't really sure the Shock Block would add much, but thought, why not? Turns out it does just what it says. I don't understand how it works, but it does eliminate that plastic slap sound. Much like a "silent spring" system in an AR gets rid of the "boing" sound of the giant spring. I don't know that there is any less recoil, but it doesn't seem quite as sharp of a recoil. My favorite [TK] item is still the Cornerstone Safety, for both the 10/22, and the PC, and just seems so natural, it is the way both should come from Ruger.

    Love this thing, much more comfortable when installed along with recoil spring
