WTB: HK33/HK93/MKE Z43 slim black handguard for 34 project

I'd like a slim black hand guard (HK33/HK93/MKE Z43/G3K) for my HK34 clone project to mount on the 34 cocking tube I've already sourced.

The MKE part would work great (starting with a Special Weapons SW5 94A2 clone I'm looking for shooting not museum quality) but is out of stock at robertrtg.
