[wachtelhund]

Hello Carrera,
The previous reply seems to have use a computer translator program and is a little difficult to read. German hunting law restricts all semi-autos used for hunting to two round magazines. As you say, breakdown is pretty straight forward. I break my HK 630 and 770 down for cleaning each time they are fired. I use a long handle hex bit driver which extends past the butt of the stock to make it easy to turn the hex screw for removing and replacing the bolt cover. I used my 770 for deer hunting in WI and remove all excess oil for the bolt and action with compressed air before use.

As for scope mounting, I find the 05 mounts for the 630 and 770 are hard to find and expensive, so I made my own scope mount. I made two little inserts with beveled edges and rectangle top to mount inside the receiver top, drilled and tap them for an 8x40 screw. Below is a picture of the two before drilling and tapping. These were a tight fit and had to be set in-place with a brass punch. I used steel inserts for the 630 and aluminum for my 770, they both work fine. A weaver or picatinny rail is set on top of the rail cover and screwed to the inserts with 8-40 screws. I used a Weaver 88 base for the receiver top and cut several slots for tactical rings. The 88 base has a radius bottom which matches the rounded forward portion of the receiver top the rear section is milled flat. This is a very solid mount. I mostly use fixed mounts on my rifles.
