Instructions for Mounting the carbon
fiber handguard, any length
Remove the small screws on the
outside of the back end. The number varies from 4 to 6 depending on the length.
Slip the rear mounting assemble out
of the carbon fiber tube.
Remove the 4 screws holding down the
Slip the GI barrel nut into the body
of the rear mounting assembly, the gear shaped end will be right under where
the U plate was mounted
Screw the barrel nut onto the upper
receiver, tighten down to proper torque spec and align a notch in the barrel
nut with the gas tube hole in the upper receiver.
Turn the body of the rear mounting
assembly so that the gas tube hole is matching the hole and the barrel nut. You
will be sliding the gas tube through all three holes, so they must line up.
Put the U plate back onto the rear
mounting assembly, with the open end towards the top. Start each screw a couple
of threads until all four are in place.
Tighten the screws, alternating back
and forth, a turn or so on each at a time. As these screws continue to be
tightened, this will cause the rear mounting assemble to draw into the barrel
nut. There is a small tab on the very bottom of the rear mounting assembly that
will draw into the bottom of the barrel nut in the notch that will be at the
bottom center. There will be a little resistance as it tightens, this is
normal, and is from the tab being drawn into the notch of the barrel nut. That
tightness helps to keep it solid and not move when finished.
Alternating the tightening on the
screws, go until the U plate is down against the rear mounting assembly flush. Make
each screw tight to finish.
Mount your gas tube and gas block in
place and tighten the mounting screws on the bottom of the gas block.
Slide the carbon rail onto the now
mounted rear mounting assembly
