Timney has been asked for a trigger at a lower price without compromising on quality for budget-build, AR-style semi-auto, magazine-fed shotguns. You asked, Timney listened. Introducing the Impact SG - our newest IMPACT designed specifically for these AR-style shotguns. Timney's engineers carefully designed each component to be precision machined – no skimping with metal injection molding or stamped, old-school parts – all while our trigger technicians hand assemble and test every trigger, and deliver at a price you asked for. All trigger parts have been engineered for excellence and are precision machined from premium materials to guarantee a lifetime of dependable service. The trigger housing is made from an aluminum alloy, and anodized blue to create a weather and corrosion-resistant trigger. To produce maximum lubricity and trigger performance, the hammer is made from tool steel, heat treated, and has a unique nickel plate finish. Both the trigger shoe and disconnector have been cut from tool steel, heat treated for durability, and have a solid black finish for an effortlessly smooth feel. With a factory set pull weight of 3-4 pounds, the Impact SG will give you a crisp, clean break.
