Key design features
- Lightweight construction: 8.8 oz without the barrel nut and only 10.5 oz assembled with the barrel nut.
- Slimline profile: Designed to provide a streamlined handguard without unnecessary bulk.
- M-LOK® mounting: M-LOK® slots at the 3, 6 and 9 o'clock positions provide mounting flexibility.
- Skeletonized design: Material is removed from areas where M-LOK® mounting isn't needed to reduce unnecessary weight.
- 1913 MIL-SPEC top rail: Maintains a continuous Picatinny rail at the 12 o'clock position.
- Notch-cut Picatinny rail: The top rail is notch-cut to match the Battle Arms Development upper receiver and further reduce weight.
- Free-floating: The handguard does not contact the barrel, supporting consistent barrel performance.
- Multiple lengths: WORKHORSE® rails are offered in multiple lengths to accommodate different barrel configurations and applications.
- MIL-SPEC compatibility: Designed for use with MIL-SPEC carbines and components.
