Hello Everyone,

For sale is my Ruger SR556/6.8 SPC. I am asking $1250. It has about 34 rounds through it. The only thing that is not stock on this rifle is the sling plate. A Magpul ASAP (Ambidextrous Sling Attachment Point). They're about $30 new. I will include the original plate as well. No expenses were spared on this piston driven rifle. The quad-rail handguard is a Troy Industries. The front and rear back-up sights are also Troy Industries. The castle nut has a couple scuffs and dings from installing the sling plate. Not really noticeable but if you really don't like it a new castle nut is only about $7. Ruger discontinued the SR556 in 6.8 SPC last year, so now is probably the time to get one before they dry up. Here is what Ruger's website has to say about this rifle:

Sturm, Ruger & Company, Inc. (NYSE: RGR), is pleased to announce the new Ruger® SR-556/6.8, a new chambering in the popular SR-556® two-stage, piston-driven, AR-Style rifle. The new SR-556/6.8 brings the power and downrange authority of the 6.8 SPC cartridge in a two-stage piston rifle that runs cooler and cleaner than traditional gas-driven, AR-style rifles.

Packaged with one five-round magazine and two twenty-five round magazines, the SR-556/6.8 is an ideal hunting rifle for those who appreciate the versatility of the customizable and ergonomic AR-style platform. The 6.8 SPC has ample power for hunting medium-sized game, and the greater muzzle and downrange energy enhances the capability of the SR-556 in defensive or tactical roles as well.

The SR-556/6.8 retains all the features of the original SR-556 that make it an outstanding value in the AR-style rifles. The patent-pending, two-stage piston delivers a smooth power stroke to the one-piece bolt carrier, which softens recoil, aiding both shooter comfort and durability of the rifle. The four-position gas regulator allows the shooter to tune the rifle to the ammunition being fired and environmental conditions present. A chrome-lined, cold hammer forged barrel provides accuracy and longevity, Troy Industries Folding Battlesights™, Quad Rail and rail covers add considerable value to the package, as does the Hogue® Monogrip®, six-position stock, sight adjustment tool, and the padded carry case, all included with the SR-556/6.8.

The SR-556/6.8 maintains the mid-length gas system and the heavy (.850") barrel contour under the handguard of the original SR-556. The 1:10 twist barrel has a standard SAAMI 6.8 SPC chambering, is 16.12" long, is threaded 5/8-24, and is capped with the effective and distinctive Mini-14/SR-556 flash suppressor. The SR-556/6.8 weighs 7.75 pounds without a magazine.
These rifles had a $1,995 MSRP on them. I am only asking $1250 shipped to your FFL. Please know your local laws before buying. Make sure your FFL will accept transfers from an individual and a copy of my DL. Will do a face to face if you're in the Rapid City, SD area. Prefer cash but am open to trades.
