ASG Ultimate Upgrade CNC Aluminum Cylinder Head - Version 3 (AK, G36, PDW, K)
by Mark H. Date Added: November 8, 2012
I installed this cylinder head in my custom SL8 DMR build. The head itself is very good quality, and when paired with the ASG ultimate silent piston, does actually quiet the gearbox down. The only thing you really hear are the gears and motor. Very good seal in the cylinder, and because of the design, I actually found it easier to put the gearbox back together with this part installed.

In my build, I used an Echo 1 MTC 3 and added an old Classic Army barrel group and fore-end hand guard. Fair warning, the mounting holes in the sides of the ASG cylinder head are small than those of the stock head. I had to drill out the holes to 11/64" for it to fit. Be VERY careful if you have to drill out the holes, because I almost crushed the air nozzle tube... use a drill press, not a pair of vise-grips.

Good seal
Made putting the gearbox back together easier (for me at least)
Silent operation.

Had to modify it to fit. May not be the case with all gearboxes though.
