The Knight's Armament KAC RAS for the HK MP5 — an extremely limited-production Picatinny rail adapter for full-size MP5 submachine guns, KAC P/N 97198.
Knight's Armament designed the MP5 RAS as a drop-in Picatinny rail replacement for the standard HK MP5 handguard. The adapter provides four rails of Picatinny real estate for mounting lights, lasers, and vertical grips on an MP5 platform without permanent modification to the host weapon. The KAC MP5 RAS has seen documented use with US military and law enforcement units that run the MP5 in close-quarters and protective-detail roles.
Compatibility is limited to full-size MP5 models — the A2, SD, and Model 94. The MP5K and its variants (Model 89/K) have a shorter, smaller-diameter handguard profile that the KAC RAS does not fit. If there is any question about compatibility with a specific MP5 variant, check with Charlie's before ordering.
This is the KAC-produced version — P/N 97198, with Knight's Armament markings. KAC releases these to the commercial market in very small batches, and they sell out quickly. For builders who cannot find the KAC version, Charlie's also carries the Cadex MP5 RAS, built to the same spec by the Canadian military contractor Cadex Defence. Both are legitimate military-contract manufacturers — the difference is the roll-mark.
We'll level with you — buy the KAC version if it's in stock. It moves fast and KAC does not give us a schedule on when the next batch drops. Order yours today.
