Yea, you have a full-auto FCG parts kit there... The parts are complete and I think these could well be Polish AKM parts or at that is what they look like to me. Most people will buy USA Parts to get your 922(r) parts count where you need them so I would replace them (I use cheap Tapco FCG parts).
You can use global trades site as a reference for your parts:

Semiauto Fire Control Group:
Full Auto Fire Control Group:
Note you have the autosear and spring, full auto disconnector, and the extra pin.
Now, if you were building a pistol or a SBR, you could simply discard the auto sear & spring, rate reducer & spring, and extra pin and grind away the extra stub on the disconnector to make it semiauto only.
Hope that helps!
