LRF,
When intalling a Mauser DST in another type rifle, it is common to weld an extension onto the "kicker" that fits to the sear, to adapt to the particular rifle. Also the military sear spring always has to be shortened in order for the spring in the DST to be able to overcome it and trip the sear. I guess you know this, but I couldn't tell from the statements above, this is not an insult.
