Best Gun Ver. 3 (Long) Cylinder Head for AUG / MK36
- Specifications
- Manufacturer: Best Gun
- Color: Silver
- Material: Metal
- Package Includes: One (1) Cylinder Head

This part seemed very appealing to me because its double O-ring provides a much better air seal than a standard cylinder head, thus increasing both consistency/accuracy and power output. I noticed that there were still some rough metal filings still attatched to the nozzle portion from the machinig process. It took about ten second and some sandpaper to solve, but still not very impressive. When it came time to actually install it, I found that the holes on the sides were not placed evenly, meaning it WOULD NOT FIT INTO THE GEARBOX. It took an hour and a half with a Dremel, grinding the holes wider and the pegs in the gearbox smaller. Great for people willing extensively modify their gearbox to get the absolute best performance, but far from reccomended to newer techs.
Pros:
Double O-ring
One Piece
Full Metal
Cons:
Poorly machined, requiring extensive modification to the cylinder head AND gearbox shell in order to fit.

I bought this after my Systema piston head broke when it's nozzle snapped at the base. I initially installed this item into a TM gearbox shell and have since moved it to a JG gearbox shell. In both cases it has fit with no issues. The double o-ring provides great compression and I have no doubts about its durability. The machining doesn't look as clean as Systema but it has worked flawlessly for me for over a year. Quality control may be an issue as the other reviewer points out but for me it worked just as I expected.
Pros:
Double o-ring
Affordable
Metal
Cons:
Quality Control
