    Our Ultra-Light and Durable mid-length handguard - the AT3 Tactical Pro Series 9" Free Float Quad Rail.


    Rock-solid 6061 Aircraft Aluminum handguard that withstands the toughest conditions

    Rail height perfectly matches an AR-15 flat-top upper receiver - your optics, iron sights, and other accessories will line up perfectly.

    Unique low-profile design - taller than it is wide (see pictures for exact dimensions). This makes our rail extremely light and easy to grip.



    Precision milled MIL-STD-1913 (picatinny) rails on all 4 rails. None of the sharp edges that you will find on inferior rails.

    Vent holes that run alongside the gas tube keep the rail cool, even after a long day at the range.

    Hardcoat anodization provides a durable surface that resists scratches and matches your existing parts.

    T-marks laser-printed on all 4 rails for quick and repeatable accessory location




    The Pro-Series Quad Rails are AT3 Tactical's most popular products - 5-star reviewed, top-tier AR-15 quad rails at great prices.

    Full kit - includes all mounting hardware as pictured below. Installation is simple, just replace your current barrel nut with the nut we provide.


    • Please Note: These quad rails are made for standard AR-15's. If you have a 7.62/.308 AR variant, check our our AR-10 / 7.62 / .308 page.

    9 Inch Pro Series Quad Rail

    This was shipped the same day I ordered it. It arrived in a couple of days in perfect condition. The quality of the item is very good. Extremely easy to install and all the parts were there. The fit and finish are perfect. This is a very good, reasonabley priced, quad rail and is well worth ordering.
