DEVILHUNTER Posted August 11, 2011 Report Share Posted August 11, 2011 As one of my shotgun receiver suffered the bad luck of be customized by Clarence Lai (a terrible job) to take Airsoft Surgeon slugshots, I have converted it to Masterkey. Some info of the real gun on wikipedia: http://en.wikipedia.org/wiki/KAC_Masterkey The first step was look for a galvanized steel profile. I found at home one that was perfect and I cut it a bit longer that I need. The sheet was 1.5 mm and I need to use the disc grinder to cut it because my dremmel was unable. I sanded it to take off the paint and the zinc that protects the steel. Why? Because I want to blue it like the real steel. Preliminary sketches and cuts Now, let's have fun: heat until red and hammering it! I make the shape to engage the barrel nut with a guide. When I bend it, the upper gap was too small to let it inserted on the barrel, so I cut the metal until the M4 barrel can pass. Then I make some cuts in the back to let it engage to the barrel nut. El cuerpo colocado bajo el cañon para ver que tal queda. Ups, I think this is too long xD Link to post Share on other sites
DEVILHUNTER Posted August 11, 2011 Author Report Share Posted August 11, 2011 I bought a M-57 QD mount for M203 to install the Masterkey in the M4. The final result. It didn't expected it, but is solid like a rock. Link to post Share on other sites
