Two-Piece Rail Covers That Install Directly To M-LOK Aluminum Handguards
The M-LOK Type 2 Rail Covers are low-profile, two-piece covers that install directly onto most M-LOK aluminum hand guards (non-polymer). These M-LOK covers are non-orientation specific, which allows the user to mount them in any direction desired without affecting function.

TSP Texture For Additional Grip
The M-LOK Type 2 Rail Covers is designed with TSP texture for additional grip and provides an ergonomic and highly modular solution to improve weapon control as well as ample protection of your rails.

Beveled Contours To Minimize Potential Snagging
The M-LOK Type 2 Rail Covers features beveled contours to minimize potential snagging with a protrusion only slightly more than 1/8″ from the mounting surface to maintain its low-profile. The center locking tab is pre-scored and using a simple, pointed tool, the user can snap off sections to mix and match colors for a customized look.

Features:
- Direct mount capability
- Cammed T-Nut
- Optimized for metal and polymer manufacturing
- Recoil/impact mitigation lugs
- Intermediate spacing option
- Multi-directional mounting
- Non-orientation specific – no up / down, left / right, front / back orientation
- Contact surfaces made of TSP
- Low profile and covers barely protrude more than 1/8″ above the rail surface
- Using a simple, pointed tool, covers can be installed or uninstalled in seconds
- Made in the U.S.A.
NOTE:
- Includes six panels, each covering one M-LOK slot.
- Not compatible with MAGPUL MOE M-LOK, MOE SL, and SGA forends, and may not be compatible with free-float handguards that have a wider and flatter profile, as they will not seat deep enough to allow the center portion to lock-in.
