i made my own viper hood about 2 years ago....basically sacrificed a multicam upper and cut it into a half shirt, added some fast buckles on is and put a 4x4 550 cord grid on it and called it good. then i made my own hood out of 2 yards of MC material bought at andy and bax. put the grid on that too.
i think i sold it with my M40 at the Old S4 to some kid for 70 bucks. it was a very easy build.
here it is at end of lies. i was with the NG team wearing ACU and had the viper hood over the uniform, i bet you can find a better pic of it in teh album if its still up.
