Rock River Arms Introduces New IRS Series

Rock River Arms IRS

Rock River Arms announced the company is now manufacturing a new line of AR-15 rifles called the Integrated Rifle Sights (IRS) series. These new guns have flip up sights that fold down to the same height as the Picatinny rail, creating a very low profile look.

The rifles have a new muzzle brake, a 16″ or 18″ (depending on model) fluted barrel, an adjustable stock and a Hogue pistol grip.

    1 MOA? Okay, we’re holding you to it, RRA.

  • Tim U

    With that raised rail to make the irons flush, won’t that disrupt all of those AR scopes with a BDC since those are dependent on being the correct sight height (among all the other factors)

  • Texas-Roll-Over

    Oh look, another AR15…boring.

    Must have some pictinny rails left over from the PDS. Re-machine, Re-anodize, re-purpose.

    • Trevor Putnam

      That was exactly what I was thinking. Bunch of parts that weren’t selling on the PDS, resell as something else that others have done better, first. Hence no KeyMod or M-LOK on a rifle for sale at $1500+ in the second half of 2015.

  • Bear The Grizzly

    I wished the back ups had rails on them too so I could add back ups on my back ups.

  • Gordon J Davis Jr

    1:9 twist and a raised picatinney rail that is going to play hell with optics and cowitnessing the integrated irons?

    No thanks. Especially not at twice the street price of a 6920.

    • john huscio

      A lot of people think the 1:9 twist is the cats meow right now.

      • Gordon J Davis Jr

        I guess 1:9 is fine if you never plan on firing anything heavier than 62gr.

        I got some 77gr SMK loads, and might even try that 100gr deep seated Outlaw round that fits in a magazine. 1:9 won’t touch those.

    Integrated sights in the rail?

    Already done by IWI Tavor

    • Andrew

      Sig did it decades earlier.

  • SD

    There are a lot more elegant ways to integrate sights. Take a lesson from KAC. That top rail looks too high, though many have risers on their optics for absolute co witness. Maybe the point is to mount optics with a basic mount and still co witness?

  • felix

    …Oooo integrated sights on a rifle fancy hmmm

    • SD

      Welcome to 2004.

  • Andrew

    Looks like a nice rifle for $800. Not for $1600.

    • John

      Yeah. I’m thinking the Internal Revenue Service would in fact be looking at the best possible cost for money. This isn’t it.

  • El Duderino

    Tears of joy! Another AR model!

    Awesome BUIS are the gun world equivalent of an aftermarket high performance parking brake for your car.

    • Isaac Newton

      well done sir. funniest comment I’ve seen in a while.

    • Bill

      I insist on a Brembo parking brake, a Danforth anchor, and a hitching post. Backups need backups. Then I use tactical chocks (Pat Pending) on each wheel.

      • ghost

        Don’t forget the beer holder.

  • Wetcoaster

    The naming is unfortunate. Integrated Iron Sights (IIS) would skip the unfortunate tax man association

    • kbroughton77

      Could be worse, they could of named it the Iron Sight Integration System

      • ghost

        Or, those things you look thru to line up a WMD.

  • thedonn007

    The raised rail would make more sense if it were piston driven like the Faxon arms upper.

  • Russ

    Total game changer…

  • Esh325

    I honestly don’t really see the purpose of such a rail. It just makes the optics higher.

  • Squirreltakular

    It’s nice that they’re offering an 18″ version. Anyone know what RRA’s barrel quality is like?

  • Grindstone50k

    “Low profile” by raising the height of the rails…?

  • Dem Gainz

    IRS isn’t an acronym I would have chosen.

  • Bill

    I first thought it was one of their agency guns, like the DEA model. I was also a little worried, it’s been maybe a day and a half since someone’s introduced a new AR.

  • BlackTalon2000

    IRS? one of the worst names ever for a product or service, unless your service is mass theft or extortion or breaking kneecaps.

  • Jim

    Pretty expensive.

  • ghost

    Another AR-15. How exciting, not.
