HIPERFIRE® X2S® MOD-3 – 2-Stage Drop-In Trigger – Flat Bow – X2SM3
The HIPERFIRE X2S MOD-3 (859177004508) is a 2026-spec premium 2-stage trigger designed for shooters who demand the control of a two-stage pull without sacrificing the legendary "oomph" of a HIPERFIRE hammer strike. The MOD-3 is the tactical evolution of the X2S line, featuring a shorter first stage than the MOD-1 for faster "prepping" of the shot and a flat trigger bow for improved leverage. It is uniquely finished in a high-performance Black Nitride QPQ coating, which provides a glass-like surface on the sears for a crisp, "weightless" break that feels significantly lighter than its measured pull weight. Unlike many competition triggers that suffer from light primer strikes, the X2S utilizes the Cam-Over Toggle Engine™, which actually increases hammer strike energy while decreasing the pull weight required by the shooter.
This semi-drop-in kit is engineered for maximum versatility, fitting AR-15, AR-10, and even high-recoil PCC/9mm platforms like the Sig MPX. The MOD-3 includes the patented HIPERSHOE® finger pad, which further reduces perceived pull weight and allows for repeatable finger placement. Shooters can customize their experience using the included Green and Red toggle springs, adjusting the total pull weight between 3.5 and 4.5 lbs. With its Soft Start Lock-Up™ technology to minimize rifle "flinch" and Radical Sear Mechanics™ for a clean reset, the X2SM3 is the definitive choice for precision long-range shooters and high-speed competitors alike in 2026.
Includes: (1) X2S MOD-3 Trigger Assembly, Hammer, 2-Stage Disconnector, (2) Green Toggle Springs (Light), (2) Red Toggle Springs (Medium), (1) HIPERSHOE Finger Pad, and (2) .154" Pivot Pins.
Key Features
- Cam-Over Toggle Engine™: Delivers a light, crisp pull while simultaneously providing a harder hammer fall for 100% reliable ignition of tough primers.
- Flat Bow with HIPERSHOE®: The adjustable finger pad increases the leverage advantage, making a 4-lb pull feel more like 2 lbs.
- Fast First-Stage Prep: Shorter first-stage travel than previous iterations allows for rapid engagement in high-stress or competitive scenarios.
- Black Nitride Finish: An upgraded, case-hardened finish that ensures lifelong durability and a friction-free sear interface.
- Tactile Weightless Break™: Provides a distinct "wall" followed by a clean break with virtually zero over-travel or "mush."
- PCC & MPX Rated: Robust enough to withstand the violent bolt speeds of blowback 9mm systems and the Sig Sauer MPX platform.
