    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.
