The brace is great but where's the buffer tube?

The Shockwave stabilizer works great, looks ok, basicly gets the job done. It does everything that the Sig model does at a fraction of the cost. I strongly suggest getting the Shockwave tube. It's hell for stout, costs much less then most pistol tubes and you'll want the detents it comes with for the set screw. That being said, I find it strange that PA has had this arm brace on sale numerous times yet they always seem to be out of the shock wave buffer tubes when ever the brace is on sale. forcing you to make another order later on. As such, the 5 stars is for the brace, I would give PA the first one star they've ever gotten for service.
