The purpose of this manual is to present the necessary engineering date, manufacturing procedures, and machinist drawings for conversion of the semi-automatic H&K-91 and H&K-93 rifles into selective-fire weapons.

In their modified condition, these weapons will function in basically the same manner as their military counterparts, the G-3 and H&K-33.  Full auto rates of fire for the converted rifles will approximate rates of fire in the original, selective-fire weapons.

Minor design changes in the commercial HK91 and HK93 have made exact duplication of the military versions impractical.  However, the information presented in this manual will explain and show these differences, as well as providing the information required for successful conversion.

Conversion of the HK 91/93 to full auto is illegal without obtaining BATF approval first.

Must Have For FA HKG3 and 91 Rifles
I own both a full auto HK G3 and a semi auto PTR 91 rifle and this text describes the main differences between both the semi and full auto versions of one of the best battle rifles ever made. Very detailed descriptions and pictures help you fully understand the function and construction of these rifles. Highly recommended! Review by Rich (Posted on 4/17/2014)
Informative Manual
Has good details of differences between sa & fa operation with good details of what parts are removed in a semi.
Also has good machinist drawings and clear pictures, very informative.
