H&K's model 94 is a
semiautomatic version of their famous MP-5 submachine gun.
It was mainly intended for
the US civilian market, and because of that, it is fitted with a 16" barrel
instead of the 8" barrel used in the subguns.
These carbines were also sold in some European countries, but they are no longer available because
production has ended.
H&K also made similar
semi auto versions of their G3 and HK 33, dubbed HK 91 and HK 93.
The Swiss company of Brügger & Thomet is offering a semiautomatic version of the MP-5 for civilian
sales. This carbine is built on a Turkish produced receiver.
