Do the TSC guns use RRs or sear packs, can a person remove the FA trigger group out of a 21 or 23 & shoot in SA ?
I guess what im trying to say is,
Will a a fullauto sear pack for a 9x series gun work on a 21 or 23, are they the same?
TSC should be able to either build you a sear ready/semi auto HK21 or convert a registered receiver G3/HK91 into a RR 21.
The sear packs are more or less the same between the 9X family. The 21 ejector needs a relief cut made to the upper front of the pack being used in order for it to fit and function correctly. That relief will not cause any issues if you decide to swap ejectors to run the pack in another host.
I will see if I have a pic of the relief cut so you can see what I am referring to.

Here is the relief cut I was referring to.
The 21 with e upgrades, but with out a swing down feed are done on a HK-91 receiver.
So, only the non-swing down would need a registered sear/pack, and yes they do work.
I'm hunting a beater 91 to send to Mike to get made into a 21....
Thats exactly what i was trying to ask, thanks for the response & the pick
So if i purchased a F/Atrigger pack, in a clone 53. I would have to make Or have made) the indention in the front of the pack as well as have some of the material on the trigger group housing above the ejector lever machined for it to just swap between 9x series & the belt feds ?
