Shedding a little light on the old school HK MP5 loadout
TPM Outfitters recently ran across a Heckler and Koch MP5 9mm submachine gun with a 1980s-era Hensoldt light.
Old school HK optic made by Hensoldt that projects light with a crosshair in the beam. It runs on 5 C batteries and weighs as much as the MP5 itself.
The SAS, most notably in their Princess Gate operation in 1980 to liberate the Iranian Embassy in London from terrs, were big fans of overhand flashlight mounts on their German made room brooms, which seems to be the market that Hensoldt was aiming at.
