The Draco pistols come into the country exactly like you see them. They can do that because they are classed as a pistol and they dont have near the restrictions on them.
The Draco is a great platform to SBR, I've built several myself. The gas system works fine the way it is, all you have to do is stick a stock on it and if you want, you can change out the furniture.
I've been doing them with Magpul grips and rigging Magpul stocks as folders and putting a Midwest Industries foregrip on them. They look good and shoot good.
Maker of cool things to shoot...
