piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder wall.
This is piston #9 up for grabs
I put the compression rings on, they come off easy if you don’t like em on.
This one is approx 2” tall and 3” diameter.

I don't know much about it, I took it on trade. Does show some use. Its not my flavor and I'm tired of looking at it. BCG is complete. The ones I've seen new typically aren't. I just discovered that it is missing the drive rod bushing, it goes where the di gas tube goes through to keep the drive...

I bought this upper from the original owner last week and honestly it was in an impulse buy as a back up to my PWS Diablo. Original owner said he put about 1000-1500 rounds through and I haven't put any through. The upper is chambered in 5.56 and in good condition and comes with a PWS flash...
Great condition DD Piston Omega 7.0 Carbine length drop in free float rail. Works on piston and DI rifles, only difference from the regular Omega is that the top section is easily removable to allow access to the piston.
Asking $160 shipped, net to me.
Hello, and thanks for taking a look. I have an extra M13.5x1LH silencerco piston for trade or sale. Works for HK and Sig 9mm, as well as others. Trade is preferred. I would like to trade for a standard 9mm piston (1/2 x 28) if possible. Feel free to email me at [email protected]. I have...
Offering a sweet price of $650 for a piston driven AR-15 (add 3% for a card transaction). More time shooting, less time scraping carbon. Would trade for a Glock G41 MOS, a nice progressive reloading setup, or consider other options.

Got mine about 3yrs ago and love it.
The model I got is the CLA , the lightest one in their line.
I'm wondering if any other members have this model or other of their gas piston AR rifles.
Mine runs like a Swiss watch, smooth and quite also alot cooler temperature wise. Typical owner up...
