Well, I decided to build my own GPMG Mounting kit based on the Belgian version. I guestimated the size tubing needed to be 1.75" OD, 0.125" wall. Here's my mount, lightly Mig welded to get me thru the parade, intend to go over it with Tig, make it look nice, and finish the locking mechanisms:
Here's my friend with his son. I bought a RCA Cadet Beret Crest for him kitted him out as a C9 Gunner. He had fun sawing the crowd the airsoft C9A1 I built from an M249 Para.
This one was taken the week before. Notice the crappy tan overspray around the stencil, just like in 2002, eh? This was supposed to be an A Coy 3PPCLI display for the 101st Airborne Division (my old outfit) Band up in Denver, but she jumped timing on the interstate, got towed home.
