Raffica Special: April 1999 - SAR ID Guide to the HK Machine Guns, Part III

By Dan Shea

In this, the third part of the HK ID guide, we are covering the basic semi-automatic variants imported into the United States by HK in Sterling Virginia. In later parts to this series, SAR will cover the clone imports and other manufactured variations of the HK line. SAR would like to thank Jim Schatz of HK Federal Operations for his assistance in this part of the series, and his and HK's help in general. As an aside, the SL8-1, a semi-automatic version of the G36 rifle with a special ten round magazine has just been approved for importation. We were unable to obtain photos before presstime, but SAR will be doing an in-depth report on this.

The two basic buttstocks on the HK semi autos are the fixed stock (A2) (Shown) and retractable stock. HK94 markings are on the top of the receiver, to the front of the sight. The HK94 is a true semi-automatic in that it uses a clip on trigger group. Probably the most desirable of the HK semi's, the HK 94 has been the host gun for many registered sear and registered receiver conversions to the MP5 format (Not by HK, of course). It is the host gun for the clone MP5's, MP5SD's, and pre-SP89 MP5K's.
