During the initial development of the RCX-76-02 Guncannonseries, differently equipped units were produced for evaluation tests. The RCX-76-01B was designed to test equipment for long distance support. A large caliber gun is equipped on the weapon platform on both shoulders, and the right arm has been replaced with a quadruple gun for short range combat. The RCX-76-01B also had a second cockpit on the head, manned by a gunner which controlled the weapons, while the control of the MS was done from the abdominal cockpit. It was found that the recoil received by the MS during the test of the large caliber cannon was greater than expected, so its use in the Guncannon First Type was rejected .
