    HK model 502

    I bought this HK model 502 shotgun. I don’t know much about it except what I heard from the LGS (rare, mainly delivered to police forces) and the little info I found on the internet

    Is anyone familiar with this weapon ? There is also contradictory info whether it can shoot slugs

    “Only buckshot can be fired due to the muzzle device that shapes the shot horizontally in an oval pattern”

    “An unusual feature of the HK 512 shotgun was special shot diverter, mounted on the barrel of the gun. It was a sort of muzzle device, intended to create oval, rather than round shot patterns. Depending on the tactical situation on hand, this shot diverter could be set (rotated) for horizontal or vertical dispersion. It also allows use of most types of standard 12 gauge slugs.”

    Inrange TV (with Ian Mcollum from Forgotten Weapons) did a couple videos on crazy chokes like this. Might be a good place to look.

    Update. HK sent me a pdf manual in German. It states that all conventional slugs can be used

    I was a bit worried because after taking one apart it is clearly larger than the diverter exit



    However the LGS whose 512 is pictured in this thread told me he fired slugs through it without problems, and the diverter is identical, except it’s mounted vertically on the 512

    Now, the manufacturer’s manual states they can be used, and the LGS has actual experience shooting them.

    So with a little apprehension I loaded just one round and fired. Indeed not problem so I fired a few more





    Next time I’ll have to try some buckshots and see the pattern
