Hiperfire X2S Mod-2 Semi Drop-In Trigger Kit, 2-Stage, High-Performance Upgrade

The Hiperfire X2S Mod-2 Semi Drop-In Trigger Kit is a 2-stage AR-15 trigger upgrade built for shooters who demand precision and reliability whether you're running competition drills, tactical training, or putting rounds downrange at the range. This curved-bow trigger delivers a refined trigger experience with a shorter, more responsive first stage than heavier alternatives, letting you control your break with confidence and consistency.

What sets the Mod-2 apart is its engineered two-stage design: a minimal, user-adjustable first stage (2–3 pounds) followed by a crisp, minimal second-stage wall and 1½-pound second stage weight. That adds up to a total pull of 3½–4½ pounds depending on whether you install the included green or red toggle springs. The distinct wall between stages is the key—it lets you "prep" the trigger by taking up slack deliberately, then break clean without surprises. Hiperfire built this around high hammer strike energy and soft-start lock-up tech to ensure reliable ignition every single time, backed by mil-grade components and precision manufacturing you can count on under pressure.

The curved trigger bow is compatible with the Hipershoe (sold separately) if you want to customize your grip further. Drop it into any AR-15, .308-style AR, 9mm AR, PPC-style AR, or Six MPX platform—this is a semi drop-in design, so installation is straightforward. Adjustment springs are included so you can fine-tune pull weight to your preference and shooting style.
