Product Description
Those cylinder guide rings designed to center the cylinder better and make a smoother pull.
also it will help with slam fire (if the old rings are worn) and improve consistancy.
the groves on the rings reduce friction area and help spread lubrication instead of wiping it.
NOTICE:
This is only 1 ring, for full kit you need 2 units (front and back)
if you only want to fix cylinder centering - replacing only the front is also ok.
they will fit any original TM or OEM cylinder (24mm dia)
steps to fit:
the rings are a bit undersized to fit any cylinder so you need to sand them with 240 grit paper to fit,
gently sand them untill they slide perfectly on the cylinder.
for the back ring you need to cut a groove for it to fit using a knife.
