sentences:  This was one of the early studies for an under-carried launcher to be mated to the SA80, and never acquired.The necessary step in equipping the SA80 rifles with an underslung grenade launcher was made only in the year 2003 with the adoption of the L17A1/A2 (a variant of the AG36 launcher).The HK69A1 was manufactured under license in Italy by Luigi Franchi S.p.A. as the GL-40/90; it differs from the original German launcher as it features a modified sliding stock assembly and different grips and sights, all made of plastic.
