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.
If your looking for one of the best AR's made (IMO), this should be a among the list. Less than 100 rounds through it. I'll miss this one. GREAT rifle.

Hi I’m on the lookout for a Wolf A1/T91 Upper 14.5 inch. 500 for used in good condition, more if new. Hit me up if you are selling one of these! Thank you.
Low round count (400-500) since purchased brand new. In excellent, original condition with a single point sling attachment the only modification. This is the piston model with the three (3) position gas regulator and will come with the Ruger gun bag. $1000 plus transfer fee.
I don't keep a round count on my guns but I bought this upper used.
Wasn't fired much before and wasn't fired by me much either.
This is the closest thing you'll get to an HK 416 (next to the HK MR556).
The 516 was made by one of the designers of the 416.
Upper comes with Dead Air 3 prong...
If you know, you know. The PWS MK111 Mod 2 is a long stroke gas piston upper with an adjustable gas block, resulting in extreme reliability and durability, especially if running suppressed. It has around 300 rounds through it and I’m only letting it go to fund other builds. Comes with the PWS...
