guarder ftk for m4s
 

i am interested in purchasing a kit but im getting mixed opinions because apparently the older ones might have bad/cheap gears and a flimsy piston.

have these issues been fixed with the newer versions out?

im looking for first hand experience if possible.

below is what i am planning on purchasing, but i will be using my M100 spring.

thanks.

Their poly-piston performance are still the same... even worst I would say. (grey version worst than blue) on the grey version instead of the end snapping off, the support of the metal tooth plate gives way before anything else.
The screw they provide for securing the piston head is too short. only 3-4 threads were able to hold the pistonhead.

Not sure if they updated the spur gear problem yet but all I know is that the axis is off centered.

I use to like Guarder's internals but not anymore. Just pay a bit more and get the Prometheus ftk set

that is what was suggested to me. ;)
