    Great value

    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.

    Noticeable Difference

    Posted by Evan on 10th Jun 2022

    This shock block gets you a noticeable reduction in the sharp recoil of the PC Carbine. Instead of a sharp whack I now get a softer muted recoil impulse. It's a noticeable difference. I recommend it.
