Daniel Defense recently announced a new rail, the MFR 12.0, that fits with the current trend of slim, slick sided, lightweight tubes. I am all for more options in this style of hand guard.
The MFR 12.0 is designed to cover a mid-length or carbine length gas system with low profile gas block. It can be run slick sided (without the rails) or 3″ rail sections can be attached where necessary via screws. The MFR 12.0 comes with 3 of the 3″ rail sections and they can be attached at the typical 90 degree angles or offset.
This style of rail is very popular right now and for good reason. It offers excellent control due to its smaller outside diameter and lighter weight is always a good thing. I am glad to see Daniel Defense venturing to offer a new option in this style of rail.
