This is a very rare and hard to find conversion kit. The HK91 conversion kit consists of a drop-in bolt and barrel adapter. It is an 18″ long sleeve that slides down the factory .308 barrel. The wider chamber part has a steel ring that acts as a friction lock so the barrel does not slide back under recoil. The HK91 Conversion kit comes with two 20 round magazines.
