Okay so I'm turning my my jg 552 into a dmr for shits and giggles. I have all the replacement parts for my gb besides the tappet plate and gears, that being said, I was told to get a full cylinder and have been reading up that it might have some neg effects on my set up. I plan on using a 300mm 6.03 tb on the gun and .28s. Should the cylinder be ported or not? I've seen answers going both ways on that.
Also... Best way to seal a cylinder head is with the grease or Teflon tape? I have more questions but alas i forgot them lol
