piston ar
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action.
I'm mostly looking for interest and that is why I haven't posted pictures, yet. I have an unfired, Sig 516 with quad rails, covers, magpul furniture, backup iron sights, sling, and 30 round mag and a case, that I am looking to trade for a BCM RECCE-16 MCMR Carbine. I will send pictures if there...

Cash price is $680. This was originally an almost $1500 rifle and I'm dropping the price way down for a quick sale.
