oh, and when i look at systema parts, whats the deal with these "area 1000" parts? how would they differ from a regular systema part?

Yeah, it's a direct drop-in. The bores are similar to Marui, so nothing else needs to be swapped.

Area 1000 is Systema's "budget/economical" line. The build quality and feature sets are equivalent to Guarder. Standard Systema are usually built with better materials and finished a bit nicer.

Yup, I do know how they work. I have them in all four of my AEGs. Like the name says, they are "taper" cylinders... so in other words, they don't use a port for ventilation. Rather, the interior is tapered, so it acts like a funnel. The piston entrance end has a wider bore than the end with the cylinder head. Depending on whether you get the shorty, middle or long cylinder, that will indicate where the end of the taper will stop. Essentially, it acts like a funnel up until where the "port" on other cylinders would end, at which point, the bore is at full close. I find it's a much more elegant solution than porting as the surface has less drag that can be applied to the o-ring. I've also noticed in tests that these cylinders seem to be just slightly more consistent than any other cylinder.

The rings simply indicate which version of the cylinder you have in your hands.
No rings = shorty
2 rings = medium
3 rings = long
