Battle Arms Development Enhanced Trigger Fi - High-Performance AR-15 Upgrade

The Battle Arms Development Enhanced Trigger Fi is a precision AR-15 trigger upgrade designed for shooters who want a noticeably cleaner break and smoother operation than standard mil-spec fire control groups. This single-stage trigger assembly features nickel-teflon-coated components and precision-machined engagement surfaces that eliminate the gritty feel common in factory AR triggers. If you're building or upgrading an AR-15 for the range, hunting, or competition shooting and want trigger consistency without sacrificing mil-spec reliability, this is a straightforward, American-made upgrade.

The core advantage here is smoothness. Battle Arms Development's nickel-teflon coating and enhanced machining reduce friction and wear patterns, giving you a predictable, crisp trigger break shot after shot. The pull weight sits in the mil-spec range—around 5.5 to 6 pounds—so it feels familiar if you're already used to standard AR triggers, but operates with noticeably less creep and grittiness. All components are 100% made in the USA and meet or exceed military specifications, so you're not trading reliability for refinement.

This is a single-stage trigger, meaning it works as a traditional fire control group replacement. The complete assembly includes everything needed for installation: the enhanced nickel-teflon trigger and hammer, disconnector, springs, and pins. Note that Battle Arms Development does not recommend this trigger for PCC (pistol caliber carbine) platforms.
