Several manufacturers have addressed the problem of how to keep an AR DCM legal and avoid having a tight sling exerting variable tension on your barrel leading to MPI shift. Rock River took the approach of having a two piece free float tube surrounded by a standard M16A2 handguard with the heat shield removed. You end up with a rifle that is hard to distinguish visually from a standard A2, but which is eligible for competition use.
- Free-float tube: Steel, parkerized finish
- Handguards: high-temp injection-molded
- Length: 13″ (33cm) long.
- Weight: 16 oz. (454 g)
- Compatibility: Fits AR-15 with 20″ barrel.
