I did what you said for the antenna. As for the guns - after trying different methods on a scrap leading edge, I ended up with two pieces of carbon fiber tube from the kite store. One is 1/4" thick wall and the other is 1/8" and fits exactly in the larger tube. Cut the large tube to a length that puts about 1/4" into the wing and about 3/16ths outside. Cut the smaller tube to protrude about 1/8th " beyond. Glue the two tubes together with med CA and make 6 assemblys. Drill 6, 1/4 " holes in the leading edge ( I did them on the Black stripe) and glue the guns in with med CA. I touched up the edges with a little silver paint to give them some definition too.
