Most modern rail systems use M-LOK attachment slots, which are in many ways more efficient than Picatinny Rails. However, if you want an M-LOK handguard on your AR, but also need small sections of Picatinny Rail to mount certain accessories that perhaps aren't compatible with M-LOK, then you need the AB Arms M-LOK Picatinny Rail Section

Made From High-Quality Material

Available in three different lengths, these Picatinny Rail Sections are made from high-quality material, which is reinforced with high-strength fibers to offer better heat resistance and durability. Therefore, these polymer rails won't get damaged if your slim profile metal handguard heats up with the barrel.

These rails can be mounted securely on any M-LOK rail and reliably hold their position. Each rail section comes with a pair of M-LOK T-Nuts and 10 x 24 - 1/2" flathead screws to mount on the M-LOK rail. These rails are an excellent way to get a hybrid M-LOK and Picatinny Rail mounting platform.
