I just removed the 47lb. bayonet lug/sight wing/muzzle cap,took off all the top wood,and shortened the lower part of the fore end to just in front of the barrel band and rounded it off. It feels like it`s half as heavy now and shoulders nice and fast. What a difference! There are "Mk7" Jungle carbines available in .308 as well as some clones in .303,they`re usually about $50 more but they have a shortened barrel and flash hider already. I`ve also seen a MkIII "Tanker" with an 18" barrel. I believe Navy Arms has a pretty wide selection of different styles all for cheap. Marcus
