Well, I'll make yet another thread about claymores, since someone didn't like me posting there.
Well, Supercell has already released the Claymore, Spring powered. No gas expense!
here's a full review I wrote on mine.
They just rebuilt these mines this week, They are very loud now, I will have a video up. it's amazing how loud something spring powered can be. It sounds like a madbull shell went off if it's indoors. These mines have all kinds of awesome accessories too, but they are professionally built.
Just throwing another option out there to you guys.
