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.

M-LOK Rail Covers, MAG603 by Magpul

Works exactly as intended, looks great, feels great, Magpul color matches all their FDE stuff. Be careful driving the top plate into the base if you don't want to separate it in into two pieces, the seam is kind of weak and will break in half. It doesn't affect the functionality and top and bottom lock in place, just advising. Thus, the 4 stars. If you can live with that, it's a 5-star product.
