Lastly , on the Century builds isn't my barrel, trunion muzzle brake and receiver made in USA, so a complete US made trigger pack would get the parts count right for 922r. Thanks
The G3 trigger pack will help with 922 and it is easier to fine tune. A couple people specialize in fine tuning them to eliminate trigger creap and lower the pull weight. Overall it is a better choice, also the CETME Pack operates in reverse to the G3 which is unnatural movement compared to thumbing it down onto fire.
OP...gulfstate's advice is the same advice I was given when I was building my first RDB rifle, concerning the trigger packs...and it's the reason I USUALLY run a Navy SEF trigger pack with mine. I DO, however, have my original CETME pack demilled and running also, and have used it occasionally. If you wish to demill one and have it for use, M1Tanker on Militaryfirearm.com has an EXCELLANT tutorial over there in the stickies under the CETME/Hk battle rifles thread.
