The KAK Shockwave Tube compliments the Shockwave Blade pistol stabilizing brace. With 12 adjustment settings, you can position the Shockwave Blade perfectly and this anti-rotation, and anti-thrust design will make sure it stays put while stabilizing your AR-15 pistol. When properly adjusted this makes the Shockwave Blade assembly very rigid for a "one big piece" feel to your pistol. Attaches to your pistol using a standard castle nut (not included) and does not interfere with QD sling type endplates. Accepts all carbine buffer systems.

  • 12 adjustment lengths

Great tube


but Magpul AR wrench doesn't fit over itAwesome tube designed for the Blade stabilizer. It's oversized to reinforce the area where the set screw contacts it. Only downside is that the Magpul AR wrench doesn't fit over it.

Works Great


Works great with the Shockwave Blade. Definitely better than a standard pistol buffer tube because of the dimples. Once you lock the brace in with the set screw its not going anywhere.

Awesome product and fantastic shipping


Well this receiver extention for the kak Shockwave pistol brace is built like a tank you could probably use it as a pry bar so it is very well made definitely worth every penny and some if you are building a pistol this is a must have product .



Got this in today and it is perfect. Finish is flawless fit into my lower is perfect...now i just need to get my blade to complete my ar pistol build

Great pistol tube.

This is a nice solid buffer tube. The dimples work well to hold the shockwave in place. It can also be used with the other arm braces.

No wobble

by -

Works great for my AR pistol. Fits the Shockwave great with no wobble once the setscrew is tightened.

Poor Quality Control

by -

I got one of these and the indentations do not line up with the notch. They are at the 7 o clock orientation making this unusable.

Works fine with my set up. To the other reviewer with 1 star, you may have just got a bad one. PA most likely will fix it without any problems.

Nice addition

by -

While not a necessity for the Shockwave brace it is an excellent addition. The tube allows you to lock down the brace positively in the predrilled divots instead of over tightening on your pistol buffer.

High quality part.

Nice heavy duty unit. I got it for a Ruger Charger build using a Copper Custom adapter. I also ordered a Foxtrot Mike pistol brace. Extremely tight fit. Had to pound it on with a rubber mallet. Thinking the KAK tube might be a proprietary unit made to fit their Blade brace.
