Hi, I'm a new member and I don't know much about HK's, Anyway I was looking around the internet and I found this picture on RTG parts.com of what appears to be an HK auto sear am I correct?
Also when you buy a registered sear, for example, a Fleming Sear what does the auto sear replace in that hole to the left where the auto sear is supposed to sit? I dont understand if the trigger pack is already a full auto pack then why install the auto sear in the first place? Any answers would be greatly appreciated Thanks

Okay but what about that pin to the left what is that?
Good read for someone not familiar with 90 series NFA conversions... lots of info that covers sears, packs, registered receivers, etc.

Welcome to the site--- I would change your username!!!
Newbie ... That is indeed a full auto sear in your original post, but you would only want to install that in a registered pack, the registered sears are similar but have a different geometry as they mount on the trigger spring axle ... and install in a semi-auto pack. If you get a registered sear you will also need the sear trip, which is the part that stick up above the trigger pack and is what the bolt carrier trips to release the registered sear ... You will also probably want to get the hammer that has been made or modified for use with the different geometry of the registered sear. I've heard of people breaking hammers so you may want to keep a spare on hand just in case ... Personally I have the modified for registered sear hammer and have yet to have one break, but I've only had it for about 5 years.

If you really want to do something, you'll find a way
If you don't, you'll find an excuse
