Hello! I'm Matt. I just signed up so if I'm posting this in the wrong area My apologies.
So, over the past year or so I've been trying to design a semi only HPA drop in engine targeted primarily for dmr builds (it could be used for any kind of build, but being optimized for dmr's by default, it would likely be less efficient.), while using a mechanical design with as few parts as possible, made out of quality yet inexpensive materials. I also wanted to aim for a very compact design, around the size of PolarStar Jack, Wolverine inferno etc.
I've already started building the prototype, and I will probably upload a pic or two when I have it in a more "presentable" state.
So, as this project progresses and/or gains enough interest, would anyone be interested in testing these?
So yep. That's pretty much the gist of it. Stay tuned for more.
