Absolutely, the main reason for going parametric was to be able to easily adapt to other internals, paint ball or airsoft or - in countries where this is allowed - to create a 'wrapper' for a real firearm.I guess I should have said, "Made available." Thanks again for all your hard work. I've been lurking on this forums for some time, and see your project is what finally convinced me to sign up to be a part of the community.
Since you're doing this Parametrically, once you have these 2 pieces ( the HDR50 and the PKD) the possibilities become almost endless. Someone (not to put all the work on you) could adapt the PKD to its little brothers, the Umarex Brodax and Elite Force H8R (BB/pellet/Airsoft versions of this marker) for those who missed out on the Airsoft PKD from several years ago.
Likewise, the bare HDR internals look a lot like Rey's blaster from the newer SW franchise, I could see adapting it to that, or to several iconic blasters, depending on fit.
I'm currently stuck a little as the cylinder of the HDR is in the way as it sits much further forward than the original Charter Bulldog cylinder. I still haven't made a final decision if I rework everything to bring the HDR internals further back or if I pretend the HDR cylinder as 'not there'...
Will keep you posted.
