Forearm

Unfortunlately, the old 392 forearm is to small a diameter to hold the A.S. tanks, though perhaps one of those slim precharge tanks would fit (I've never seen one in person), might be a great way to stealth the co2 souce. It would look JUST like a pumper 392.
Ahhhrghh....Inspiration Strikes again !! and here I thought it was as good as it could get. HAHAAHAHA
A modders work is never done.
