INSTALLATION
NOTE
The rail covers perform two primary functions. They are configured to protect the
shooter's hands from direct skin contact with the metal parts of the adapter rail
which gets hot during extended firing. They also protect the rail surfaces from excess
wear and damage. For these reasons, rail covers should cover the unused sections of
each rail of the adapter rail at all times.
Several different lengths of rail covers are provided with the handguard assemblies.
For ease of reference, they should be identified by the number of ribs along the outer
surfaces, i.e., "11 rib," "9 rib," "5 rib," and "4 rib."
All rail covers are interchangeable between rifles and carbines (carbine set includes
two 2 rib and two 6 rib sections).
1. To cover the side and bottom rail surfaces, install rail covers (1) from muzzle end of adapter rail.
Longer rail covers on carbine should be oriented with spring tension clip (2) toward muzzle (L-28, R-28,
or B-28). Longer rail covers on rifle should be oriented with spring tension clip toward chamber (L-14,
R-14, or B-14).
2. To cover the top rail pull charging handle to rear and install rail cover (1) from rear of upper receiver
group.
3. As spring tension clip (2) meets its cutouts at either end of rails, clip will engage cutouts to secure rail
cover (1). Shorter rail covers (used on rails partially occupied by accessories) should be oriented with
spring tension clip away from accessories.
