This is a custom built, “HK51K” super shorty, in 308/7.62×51. HK parts were used for everything except a few custom parts in the front section, barrel, locking piece and receiver flat.
Hours of custom metal work and fabrication goes into these… This is not an off the shelf HK but it is based on the HK roller lock platform and uses as many HK parts and specs as possible.
Very unique, very custom and very rare. We only build one of these every few years so let us know if you’re interested in them or add yourself to the wait list to be notified if and when we have another!
