Intended for the AR-15 platform, the Verge M-LOK 12 Rail from Firefield utilizes a skeletonized design and hard anodized aluminum construction to provide an incredibly lightweight and durable handguard. Verges employ a low profile design, contributing to an overall slim rifle. All M-LOK accessories are compatible with this rail system. The rail includes a 7 slot M-LOK rail piece and hex key.
