Systema Reinforced Teflon Cylinder and the KM Teflon Coated Power Cylinder
 

Just want to see everyone's opinions on the Systema Renforced High Performance Teflon Cylinder for M4 and the KM Teflon Coated Power Cylinder. They are going to be used in conjunction with the Systema Silent Piston/ Cylinder Head set. I want your opinions or experiences with these products. Naturally I would think using all sytema parts or all same branded parts would be the best idea but if you have had a experience that suggests otherwise please feel free to post.

Based on the part number, that is actually the KM TN coated inner taper cylinder, which is what I use in all of my AEGs.

Performance-wise, based on numbers achieved from BB velocities, this cylinder performs the same as the Systema one, but based on the design of the KM one, in theory, the piston head's o-ring should last longer than in the Systema one.

Thanks ILLusion.

i just bought one KM TN coated inner taper cylinder, but i couldn't decide which is the front side (to install cylinder head) can you give a simple direction.....

You have to feel the inside wall of the cylinder. As you rub along it, you'll feel where the material begins to taper out. The open tapered end is where the piston enters. The tighter end is where the cylinder head sits.
