Figure 1. Placement of Handguard Assembly for Repair.
CAUTION
The handguard assembly is aluminum; therefore, care should always be taken not to
damage or burr the slots of the rails.
NOTE
The spring pins in handguard assembly must be replaced with new pins each time
they are removed.
A good one person method for removal of the spring pins to do repair work is to place
a short piece of 1" x 4" wooden block under the rails. A two person method is to hold
the handguard assembly along the side and over a corner of a wooden work bench.
