systema area 1000 cylinder type 1
my friend had bought this originally, but I got it since he needed a type 2.
it is installed in my upgraded JG m16, and I have found that if you have good compression and no air leaks in the systema, the type 1 is more effecient than the type 0 for a m16 length barrel. The gun shoots 440 fps on a m130 with the type 1, but only 410 with the type 0. There is simply too much air in the type 0.
-teflon coated (don't need much grease in it)
-it works awesome
