Does this kit make the pistol a SBR?
Corey T on May 16, 2019
BEST ANSWER: Under federal law, no, it is considered a pistol with a brace, but you should check your local and state regulations for the status of legality in your area.

I liked the shockwave pistol brace. The rest is a basic lower parts kit.
This is my first build so I have nothing to compare it to but it seemed to be good quality. All of the parts were seperated into sections or groups of parts, which I found to be helpful. Each step of the build was in it's own sealed bag so it was not confusing looking at all of these different small parts. I am very satisfied with the product.

Nice kit but fcg doesn’t work
Trigger disconnect doesn’t fit into trigger, not sure if the channel on trigger is to narrow or disconnect is to thick will try to file and fix it but normally wouldn’t get bad parts from PSA!

Great kit!
The build kit is really nice. I really appreciate how all of the parts for each component are bagged separately for easy identification of all the similar pins and springs. My only real complaint is that the gray color doesn't match up perfectly with the gray Magpul handguard I have. The handguard is slightly darker and duller in color. I don't know which of the two is the standard for "gray" parts, or if there even is one, but it's just something to be aware of.

Worth every penny
One of the best braces on the market and I can see why. I hated the grey so I used Brownells Aluma
Hyde in FDE.
