For sale is my Ruger SR556 piston powered AR pattern rifle. It works as Ruger advertised - it's a high quality rifle, runs clean and is very accurate. This is the original version with the chrome lined barrel, not the later and cheaper E version which had a plain barrel. The rifle is in excellent shape cosmetically and functionally; the stock Troy flip up sights are still on the rifle. I have an Aimpoint Comp M4S with flip caps and an ARD or killflash on top of it and there's a Surefire M951 light mounted to the underside rail. The light is controlled by a Surefire pressure pad on a genuine GripPod vertical foregrip. I've put a CAA riser on the stock to get a good cheek weld with the Aimpoint. This has been a great rifle and I'm going to miss it. Comes with the pictured hard case and four MagPul PMAG magazines. Not interested in trades, asking $1200 for the set but may entertain offers. Located in the DFW area but can meet within reason.
