"I'm not sure what Matthew P. was doing wrong but I have had zero issues with this head. I assembled and disassembled my piston assembly several times while working on my tuning and adjusting things and I haven't noticed any wear, even on the screw head. The build is good, I got flawless compression using this and an Angel Customs steel cylinder and Lonex cylinder head. Great quality, solid piece, just be sure to use threadlock when putting this together with the piston.

"Used as a replacement for my G&G combat machine in my SSG build. Works great and haven't had any issues with it

"This piston head gave me great compression bit the screw is very weak and stripped, I went through 3 replacement screws. I do not recommend this in high stress builds such as DSGs and this would be a strictly SSG build only piston head.
