I'd like a big stick duct taped to the end of my sniper so when I'm still i can put the stick down like a long stand and it increases the accuracy and there is no scope shake : D
Well, we cut Y-shaped yokes out of wood to prop our M16s on when I was in the Marines, and I once repaired a bolt assembly with rubber and red clay mud. So I am a firm believer in the practicality of sticks and duct tape in the wastelands of the Mojave.
What could be more awesome in a post-apocalyptic setting like Fallout than McGuyver-ing the crap out your weapons and gear?
