For the purposes of color matching your components, Flat Dark Earth and Olive Drab Cerakote correspond to the same colors in the Magpul pallet. Hand guards are run in Cerakote regularly on an as-ordered basis, which may add up to 2 weeks to delivery time.
Tactical Rail Selection
Any rail segments purchased at the same time as MK III Hand Guard are available at 20% off when selected from the the menus at right. All rails are anodized black regardless of any color option upgrade.
Full-length 12:00 rails or the 2-inch front sight rail (JPTR-FS) can be attached directly to the top of the hand guard tube while two- and four-inch accessory rails can be mounted directly (without backer plates) to the tube at the 6:00 position using the 10-32 flathead screws included with the rail segments.
For the 3:00, 9:00 and each of the 45° positions, the Signature tube design uses rail segments with backer plates that fit into the tube slots. Refer to the table below to determine which rails you need for a given application.
This hand guard is not compatible with newer Bushmaster CARBON-15 rifles. Rifles with serial number E18000 or higher use a barrel nut thread size that is larger than standard, so standard AR-15 free-float hand guards cannot be installed.
