Using
a pair of pliers or the bullet tip of a cartridge,
rotate the takedown lever located on the right side
of the rear sight base upwards. |
| Takedown
Lever in unlatched position |

|
With
the lever not quite vertical, grasp the rear end
of the upper handguard/gas tube assembly and lift
it up from the rear sight block. It might be necessary
to wiggle the takedown lever back and forth to locate
the release point for the rear end of the upper
handguard/gas tube assembly. Once the rear end of
the assembly is clear of the rear sight base, pull
the front of the gas tube away from the gas block. |
Using
an open end or adjustable wrench, fit the wrench
to the flats on the rear end of the gas tube, and
grasp the upper handguard in the other hand as shown.
While holding the wrench and the upper handguard
firmly, GENTLY rotate the upper handguard 180 degrees.

The
upper handguard can then be withdrawn from the gas
tube. There is a stamped tension spring under the
upper handguard and this can be pried from the upper
handguard with fingers or a small screwdriver or
pliers. The stamped tension spring is installed
on the large (or rear) end of the upper handguard,
and is installed toward the rear end of the gas
tube (the end with the flats.) |
| Using
a screwdriver or pliers, grasp the short lever at
the right front side of the lower handguard. Rotate
the lever up and to the front, approximately 180
degrees from the latched position. |
