B&T USA Replacement Trigger Spring - Factory OEM Fire Control Component, High-Memory Spring Steel, Natural Metallic Finish - BT-36375
Product Description
Maintaining the crisp presentation and split-second control response of a premium tactical platform requires fire control components calibrated to precise engineering weights. Standard generic trigger springs or worn-out factory hardware can suffer from dynamic tension loss over long periods, leading to mushy trigger break weights, slow trigger blade return vectors, and unexpected reset failures during rapid range training. The **B&T USA® Replacement Trigger Spring (BT-36375)** completely flatlines this reliability bottleneck. It delivers an authenticated, Swiss-engineered factory replacement spring built to restore crisp, positive trigger response.
Proudly manufactured to strict duty specifications, this high-durability torsion spring is precision-wound from premium **high-memory structural spring steel wire**. The wire matrix is treated to withstand millions of compression cycles without taking a permanent set or dropping tension. Positioned directly over the primary trigger sleeve hub within the lower receiver pocket, its dual extended retention arms distribute force evenly against the trigger frame floor. This guarantees a smooth, predictable trigger pull and a sharp, tactile reset tracking cycle every time you press the shoe.
Engineered to slide natively onto standard factory trigger pins alongside the OEM disconnector and trigger shoe block, this turn-key armorer component ensures original equipment safety and function straight from your workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The B&T BT-36375 component package arrives workspace ready as a single replacement dual-arm trigger torsion spring module. PROPRIETARY COMPONENT INTERFACE MATRIX: This internal spring is engineered natively, strictly, and cross-compatibly to interface with **B&T factory fire control trigger sleeves and shoes**. *Platform Fitment Checklist:* It serves as an identical replacement part across the **B&T APC9/45, APC223/300/308, GHM9, and SPC9 series polymer or aluminum lower receivers** on your bench. System Tuning Notice: This is a standard duty-weight factory replacement spring designed to keep your weapon within safe tactical operation boundaries. It is not an aftermarket lightened match modification. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host firearm platform is completely clear of live ammunition, the magazine is separated, and the chamber is safe. 2. Field strip the weapon to separate the lower receiver housing completely from the upper receiver chassis group. 3. Relieve spring tension by carefully riding the hammer forward into the fired configuration. 4. Use a standard 5/32" drift punch tool to push the main trigger pin out of the receiver wall slots. 5. Lift the trigger shoe core up out of the lower chassis pocket, keeping track of the legacy spring configuration alignment. 6. Slide the new BT-36375 trigger spring over the trigger sleeve hub, ensuring the center loop matches the pin channel alignment and the twin legs face forward toward the frame base. 7. Reseat the trigger assembly into the lower receiver, slide the pin back through, and test trigger pull and reset tracking manually before reassembly downrange.*
