OOPS !!! I stand corrected.
Trickyrick, that is a fantastic PPS-43 carbine you built on weaponeer !!! The Omega PPS-43 parts kits were about the first imported into the US decades ago from PRC. They were dewatted to a different criteria - which torpedoed the folding stock mechanism. They did however have more barrel shroud/trunion material left vs today's dewats.
