"fit perfectly into my gearbox, does its job, tight fit with an angel customs cylinder which is great and extremely silent with the matching piston head

"I ordered this cylinder head along with the matching ASG Silent Piston Head for my CYMA Beta Spetznaz Ak. My problem, it doesn't fit despite the CYMA having a Ver. 3 gearbox. There's an extension on the cylinder head that makes it too long to fit I to the gearbox. But don't let this stop you from purchasing this product. It did mate up to both a stock CYMA and a stock G&G cylinder no issues at all and produced quite a nice air seal without any modification.

-Cool color and finish
-Quality material
-Good air seal
-Compatible with an array of cylinders

-Doesn't fit in certain CYMA Ver. 3 gearboxes.

Order with caution!

"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.
