The model of the CMR-76 and its magazine is almost identical to the QBU-88, however all the research I have conducted so far suggests that the QBU-88's default magazine carries 10 rounds of 5.8x42mm. The current CMR-76 can hold 20 rounds of 6.5mm in a magazine that looks identical to the QBU-88's. Perhaps alter the magazine model or reduce the magazine capacity to 10 rounds in game.
