maybe closer to what it could look like, the upper is actually nestled in the lower, the upper would need to be made longer though, but just imagine

if you think about it, sheet metal gun meets sheet metal gun
Hmmmmm....interesting.....kind of a short MAX-31 that takes HK mag's with HK sights, HK K-grip and HK Stock. Couldn't use a HK clone upper since it is the registered part. It would look better with the M-11A1/380 due to the shorter rear receiver.
I have also thought about making an upper styled after the Spectre. Cool little SMG. One of Practical Solutions side folding stocks would look great on it.
I've also thought about making an HK UMP styled upper, except made out of metal of course.
The down side is that to use the HK mag's, I would have to get another determination letter from BATFE.
Our company focus is on products for conpetition, but these uppers would make for some fun guns.
We are just brainstorming here. PLEASE...do not call or e-mail me to be added to a list for anything we posted here. I know how you guys like to be first on a list and get a jump on things.
Our focus right now is to get production back up and running in the new shop.
