TPS Arms Enhanced AR-15 Trigger Group 5.5 lbs. Pull Weight - AR2005
Product Description
Standard factory mil-spec fire control groups provide a reliable baseline of safety for modern sporting rifles, but their mass-production tolerances introduce an immediate mechanical bottleneck. Stock triggers frequently exhibit a gritty, uneven take-up, heavy stacking friction, and excessive pre-travel creep that compromises clean finger control and leads to subtle muzzle deviation at the exact point of ignition. This unpredictability limits a shooter's downrange accuracy potential, especially during intensive training or general-purpose duty applications. The TPS Arms Enhanced Trigger Group (ETG) completely redefines standard single-stage fire control assemblies, eliminating inherent mil-spec grittiness while maintaining the unyielding drop-safety and reliability required by frontline service platforms.
Precision-manufactured in the United States from premium high-tensile steel alloys, this complete 7-piece conversion engine is engineered to deliver a remarkably consistent, crisp trigger break. The kit incorporates a meticulously contoured trigger bow, a hardened hammer, a fine-blanked disconnector, high-grade duty springs, and centerless-ground hammer/trigger pins to guarantee optimal internal tracking alignment. Every component features a uniform protective black finish that resists environmental moisture, abrasive carbon grime, and aggressive cleaning solvents. By tuning internal engagement geometries, TPS Arms successfully removes performance-inhibiting grit while strictly adhering to the M4/M16 minimum pull weight specification of 5.5 pounds, ensuring full compliance with official duty and safety standards.
In tactical or recreational workshop applications, the ETG functions as a highly practical, drop-in performance upgrade that immediately transforms your rifle's manual of arms. By sharpening the trigger response and smoothing the travel arc, this fire control group provides the shooter with superior tactical feedback, allowing for predictable shot placement and stable tracking across extended live-fire strings. Furthermore, the optimized reset geometry reduces sluggish forward cyclic lag, forcing the trigger shoe forward with snappy velocity to facilitate faster, more controlled follow-up shots. Backed by a limited lifetime warranty, this affordable upgrade bridges the gap between cost-prohibitive match triggers and loose commercial options.
*Armorer Bench Notes & Technical Maintenance Guidance: The TPS Arms Enhanced Trigger Group (AR2005) drops natively into standard small-pin (.154/.156 inch) AR-15 lower receivers and matching large-frame AR-10/SR-25 pattern platforms. During bench installation, ensure the small disconnector spring is oriented with its wider, flared base seated down inside the rear trigger cavity pocket before overlaying the disconnector itself. When positioning the hammer assembly into the receiver, verify that the two long legs of the hammer spring rest perfectly flat across the top outer grooves of the trigger pin, as this configuration acts as a mechanical anchor to prevent pin walk during high-volume strings. Apply a micro-dot of premium high-viscosity synthetic gun grease directly onto the primary hammer sear notch and the disconnector hook to achieve maximum slickness and a glass-like reset. Always perform a comprehensive safety and function check with the upper receiver detached or using a specialized hammer block, as allowing the hardened steel hammer to strike an empty aluminum lower receiver face can fracture the bolt-catch ears.
