H&K makes the best piston followed by LMT. I would not even give consideration to the other two of them. To many issues with guns being returned to the builders because they dont work right. Also the price is way over the top for what you get.
LMT and H&K are both gov contractors
I own the LMT with piston and DI barrels. The only reason you need a piston and need is an overstatment is if your going to run your rifle supressed.
My suggestion would be (and I base this on my personal experience) Is to get a quality MIL SPEC weapon from a good company like LMT,BCM,Noveske,colt,Daniel Defence or Knights these weapons are all of proven reliabilty and do not even come close to compairing to hobby guns made by busmaster,DPMS,stag,CMMG, insert name here etc.
