I've been working on this idea since I first bought a SU several years ago. Not satisfied with the look and quality of the other stock options, I teamed up with my buddy who is a CAD designer, and set out to make our own. This is a rough prototype that has been 3D printed. The final product will be machined out of 7k series aluminum. It is set up to use AR grips with or without the beavertail. The rear has two tapped holes that will fit any Ace style modular stocks and folding mechanisms, so you can run more than just AR stocks now! Here it is shown on a PLR with a sig arm brace. This rough prototype was just to prove fit and function, which it does fire like this in ABS plastic. We will now focus on smoothing the design, trimming some fat, and making an aluminum prototype. When we get the design finalized I'd like to get some Beta testers on this forum to get some feedback. Thoughts?

I concur, it looks great! My only comment/question is why aluminum vs. some sort of polymer or other printable material? Not sure if the aluminum will make things too heavy or not. The light weight of this rifle is one of the big draws for me.

I know molding equipment is likely cost prohibitive on a small scale, but if it's printable...

I'm sure the folding mechanism is easier to integrate with aluminum vs. a polymer too.

Being molded out of plastic would be great if we were going to make 20,000 of them, but not for just a small amount. I was just trying to generate interest to see if people would be game to the idea. The 3D protos would work, but not sure how durable they would be, especially in the stock mounting area, plus the finish on them is less than desirable. Once we have an aluminum model, we can outfit one with a standard M4 stock and grip and do a weight comparison against the Keltec grip/ M4 stock combo. My guess it will be a tad heavier but not by very much.
