thanks bkeeper (are you really an apiarist?) what do you like about the v3 over the v1? I wanted the folding stock, I don't care about the flash hider (I wonder why they don't call it a muzzle brake? they must be from a free state) what is hard about removing/changing is it welded on? what bbl length is your model 3? How different is the heavy bbl is that only for the 6.8SPC? thanks again you gave good insights to the case law I never even considered that. I have the KelTec SU16CA and wanted something more substantial. I have no doubts that this is a good weapon system I once saw their M96 at a gun show and was impressed and since in another life I was familiar with the Stoner 63, Armalite AR-18, and Daewoo K2 rifles I figured they (RobArm) have something really good to offer here.
