This is what makes owning an AR-15 such a personal, customizable experience, as every aspect of it can be modified to suit the user. For all users though, having the right rails is crucial for top performance, and rail covers are an important part of having optimal heat protection and added comfort and grip. However, not all rails and rail covers are the same. Let’s check out some of our top picks for 2021.

The Arisaka Low Profile Picatinny Rail is a 5 or 3 slot Picatinny rail for KeyMod handguard systems. It offers a reduced height to pull any Picatinny accessories closer to the handguard. This reduced height is a subtle, but highly effective feature, which is one of the reasons why this rail has so much value. The 5 slot model connects with three of BCM’s patented reverse threaded KeyMod screws which will spread the increased stress of large Picatinny accessories like bipods or vertical grips over more KeyMod slots. The 3 slot version is useful when less rail space is required.

 

3. Magpul M-LOK Rail Covers

Magpul M-LOK Rail Covers

Talk about amazing value! At just $12.95, these M-LOK covers from Magpul are an absolute steal.

These M-LOK covers are non-orientation specific, which allows the user to mount them in any direction desired without affecting function. At this price level, having the non-orientation versatility is an awesome benefit.

These covers also feature beveled contours to minimize potential snagging, and a TSP texture for additional grip, and with a protrusion only slightly more than 1/8″ from the mounting surface to maintain its low-profile. The pre-scored center locking tab allows the user to snap off sections and mix and match colors for a customized look. Important to note is that these rail covers however are 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.
