AR-10 Zero™ Trigger - Flat

The AR-10 compatible Zero trigger features a powerful 17-7 stainless steel hammer spring and heavy S7 hammer. This change ensures increased reliability across multiple variations of .308 and 7.62×51 NATO cartridges available.

The short 2mm reset makes the Zero trigger one of the fastest on the market.  The reset is also positive, which facilitates even faster shooting during training or competition.  The trigger, hammer, and disconnector are EDM cut and then polished with brass wire to a micron finish in all critical contact areas for a friction-less engagement.  The trigger tail is enlarged and its shape modified to cup the safety drum for safety and to eliminate pre-travel.  The pull-weight and disconnector set screws are also welded after loctite for safety and a lifetime of use.

Zero™ AR-10 triggers are available in a pull weight of 4.0 lbs and two finish options for the internal components (trigger, hammer, and disconnector):  Black Nitride and NP3.  Black Nitride is a heat treatment process that enhances corrosion resistance, improves lubricity, and leaves a fine black finish on the surface of the metal.  NP3 is a plating of electroless nickel co-deposited with Teflon that provides remarkable lubricity and takes on the appearance of the base metal.

In short, all of the features of the Zero™ trigger are designed to offer a shooting experience that is exceptionally smooth, crisp, and fast.
