Heckler Koch HK 05 Scope Mount fits 300, 630, 770, 940, SL6 / 7. In Excellent lightly used condition. Absolutely no rust or pitting. This mount has been cleaned in an ultrasonic bath, air dried and then lubed. I post clear easy to view large pictures of all sides. No Bleacher seat shots. The minute the paperwork says gun parts. These mounts are getting harder to find because people just aren’t willing to part with them. It’s like an addiction with these HK G3 hunting rifles. When you own one you are gravitated toward the other models. They all take the HK 05 Mount. Treat your German marvel to the upgrade it deserves. Don’t waste your time with those aftermarket if you can find them cheap cast aluminum mounts that you tighten a slotted screw, they are junk and don’t hold zero that’s why they stopped making them. No lazy cut and paste or bait and switch here that others may pull. The Base in the pictures you see is the Base that you will be receiving. The HK 05 Base is made to accommodate both the 30 mm and 25 mm standard one-inch U. I also have a very sweet German made Picatinny rail that will slide right in. I personally have them on all my HK’s with different powered scopes and they all hold zero after several years. I do not have to sight my rifle in every year for hunting or the range saving me big on ammo. Your HK 05 base will come wrapped in VCI paper and sealed.
