King Arms – 13.5" RAS
The King Arms, 13.5" RAS is a replica of the Troy Industries MRF-RX rail system. It is a 2 piece, free float rail system.
The King Arms version is a very well built system. All metal and built to high tollerances.
I mounted mine onto a Magpul Metal Body and it was a very straight forward install.
