The Cloak Industries MFR 56 belt-fed upper in FDE is a complete 5.56x45mm NATO upper that converts a standard AR-15 to belt-fed operation with minor changes (brand part no. CLK-MFR556-FDE-BNDL). Imported exclusively for Cloak Industries from System Defense, it runs a short-stroke gas piston with a two-position gas block and a quick-change 16-inch CrMo steel barrel with a nitride finish. The dual-feed design accepts either an AR-15 magazine or belted links, so the same upper handles both. This version wears a Type 3 anodized FDE Cerakote finish over aluminum and steel. The bundle includes the gear needed to start shooting, from a 100-round belt container and 100 links to a sling and a Savior double rifle bag.
