The BAVTAC Crown Nut Tool (CNT) is specifically designed for the Tokyo Marui MWS GBBR. It perfectly fits the barrel nut on the CQBR and Carbine models of the MWS, as well as the crown nuts on the buffer tube.
Made from 4mm steel, this tool is durable and allows plenty of torque transfer to the nut. With 3/8 drive cutouts, you can even use it with a 3/8 ratchet for extra torque — perfect for breaking Loctite.
