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.

Tube Position JP Tactical Rail
12:00 JPTR-XL, JPTR-R, JPTR-M, JPTR-FS
6:00 JPTR-LRC, JPTR-SRC
3:00, 9:00 and 45° JPTR-L, JPTR-S

Compatibility

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.
