So according to this article. the Evo has 16 parts and the CZ SBR kit takes it down to 9 instead of the required 10.
http://www.thefirearmblog.com/blog/2015/07/14/cz-scorpion-evo-3-922r-kit-update/So if this is correct can I choose the US parts of my choosing and NOT do the disconnector?
My list would be
1) Straight non-folding stock
2) Shooters or HB trigger
3) Yeti grip
4) US follower
5) US base plate
6) US muzzle attach
(EDIT...answering my own question)
In the comments in that article I believe is the answer.
Actually, I believe the stock is still foreign-made - so they include 6 US-made components in the kit.With the CZ foreign stock they get down to just the required 10 so the US-made-disconnector is needed.
Conversely if I choose an alternative US stock solution then you can avoid the disconnector swap.
