Civilian one confirmed (and half life 3)!
No.
There is a difference between "semi auto only" and "civilian" gun.
In general, all automatic rifles - that includes both semi automatic and fully automatic guns - are deemed "weapons of war" in Germany (see
Anlage KrWaffKontrG - Einzelnorm No. 29 c) and d) ) except for certain historic weapons that are exempt.
Semiautomatic rifles specifically designed and constructed as "hunting or sporting rifles" are also exempt.
A HK433 with a semi only trigger pack is still a "weapon of war".
A potential semi only MR443 is not (that design has to include provisions that the gun cannot be easily converted to fire fully automatic, e.g. just by swapping the trigger pack).
This is one of the reasons that the civilian FN SCAR versions aren't available in Germany as FN won't provide statement and proof, that the FN was "specifically designed and constructed as a hunting or sporting rifle".
There has been a dealer that lost his license due to importing a 16S and a 17S, thinking that it would be a "civilian" rifle here. And others are selling Tavor X95s thinking that they are civilian guns due to being semi automatic and it must be okay as they are sold in other countries (Austria e.g.). Those are ticking time bombs...
Sellers and buyers may get visits some day, as they sometimes openly trade that stuff:
