I remember reading that Ruger designed their own piston system, but I have no proof to back that up. They do have a patent pending on the piston design though, so I don't know if that means anything as to who's the designer in this case.

How many different piston-driven designs are there for the AR?
Not being completely immersed in this market, I'm aware that several vendors sell/rebrand other manufacturers piston designs. What I'm looking for is to compile a list of the first-line manufacturers as well as their downstream re-branders. To start the list I can think of three most obvious. First is the originator and after the hyphen is the re-branders.
What else? Who else?
To be clear, the ACR, XCR, SCAR, etc. are not up for consideration here. What we're talking about are AR-pattern carbines with the primary change, or only change, being in the relocation of the piston from the BCG to somewhere between the gas-block and the upper.

PWS- Primary Weapons Systems, Inc has a very good system.

Didn't you cover them in the "Hot Air: Why Piston ARs Suck" article? (Surefire Combat Tactics magazine, Fall 2010)
Some valid points are raised in that article, for sure, but I'm somewhat surprised that no one has covered the reasons behind the genesis of the HK416 and all of its other followers: suppressed SBRs. I'd bet that 99.5% of the rounds fired by civilian AR shooters in the US are unsuppressed, and out of 14.5"+ barrels.....simply due to NFA. So for the civilian AR market, logic would dictate that the market for piston ARs should be small. Due to the flip side of NFA, however, for mil/LE the market for piston ARs should be growing.

I'm not a fan of the piston as I think it is a solution to a non existing problem, but the PWS is the only one I would consider if I was one of those guys who has to try everything.
A couple of class iii dealers down this way have torture tested them with good results.
I will admit that I have no idea how their design compares to the others listed here as it's the only one I have fondled.

I did, but even then I was (and remain) unsure of who is using who's design.

No they shouldn't. After using a properly configured DI gun in suppressed SBR form, I won't go back to pistons.
It isn't worth it.

Smith and Wesson offers 2 piston guns. One is a California legal with a gas block I don't recognize, the other appears to be an Adams Arms kit.

I thought Addax Tactical and Primary Weapons Systems used the same piston system?
Adams Arms produces systems for S&W, Spike's Tactical, and Rainier Arms. To add further confusion, Adams Arms has three different gas blocks - one with a rail that's held on by two screws, another with a rail that's pinned, and another that's pinned with no rail. Honestly, I think probably half of the piston systems out there are based on the Adams Arms design. For example, the Barrett, Stag, and SIG all appear very similar to the Adams Arms design.
