B&T USA Ambidextrous Selector Kit - Factory OEM Safety Overhaul Assembly, Hardened Tool Steel & Polymer Levers, Black Finish - BT-KIT0008
Product Description
Maintaining or restoring the safety framework of a high-performance submachine gun or pistol-caliber carbine requires factory-original replacement parts built to precise Swiss tolerances. Legacy, worn, or mushy selector linkages can lose their crisp tracking detent positions over thousands of field manipulations, threatening weapon safety profiles or causing erratic positional tracking downrange. The **B&T USA® Ambidextrous Selector Kit for APC9/45 (BT-KIT0008)** completely flatlines this wear bottleneck, supplying a full factory-calibrated ambidextrous safety upgrade and component replacement overhaul package.
Proudly engineered by Brügger & Thomet to professional duty specifications, this comprehensive armorer kit includes the central multi-axis safety barrel drum, the right-side pointer lever pad, matching factory detent plungers, and heavy-duty coil tension springs. The core structural selector drum is precision CNC-machined from **hardened carbon steel alloy**, treated with a matte black anti-friction phosphate layer to survive severe rotation cycles. The tactical thumb levers are formed from B&T's proprietary **high-impact polymer compound**, complete with precise linear scaling grids to ensure a non-slip tactile purchase when driving the weapon between "Safe" and "Fire" positions under high-stress drill scenarios.
Engineered to drop natively into the factory frame alignment ports of your lower receiver, this turn-key refresh package ensures distinct safety engagement arcs and crisp mechanical feedback straight from your workbench.
*Armorer Bench Notes & Real-World Receiver Staging Guidance: The B&T BT-KIT0008 package arrives workspace ready, containing 1x main safety selector center axle with attached left-side lever, 1x secondary right-side thumb selector pad, 2x precise factory safety detent plungers with pre-fitted coil springs, 1x auxiliary compression spring, and 1x mechanical interface roll pin. UNIVERSAL COMPONENT FRAME INTERFACE MATRIX: This overhaul array is engineered natively, strictly, and cross-compatibly to fit **standard B&T factory APC polymer lower receivers**. *Host Weapon System Checklist:* It perfectly overhauls or upgrades the **B&T APC9, APC45, GHM9, and SPC9 sub-guns / PCC variants** utilizing original B&T factory trigger framework systems on your bench. System Configuration Notice: This safety block is calibrated for standard semi-automatic layouts; it preserves the original factory 90-degree manipulation throw path from Safe to Fire. 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 isolate the lower receiver frame onto your workbench workspace pad. 3. Use a micro roll-pin punch tool to drift out the retention pin securing the right-side selector pad to the center axle drum. 4. Slide the legacy right-side indicator off the axle, then carefully pull the main safety barrel out through the left receiver wall, being cautious to trap the internal spring-loaded detent plungers as they vent out of the receiver block cavities. 5. Clean the drum tracking ports thoroughly with a nylon brush to clear carbon dust buildup. 6. Lightly grease the steel cylinder tracks, drop the new detent plungers and springs back into their receiver pockets, push the main axle barrel through, align the right-side paddle over the indexed axle tip, and tap the locking roll pin flush downrange.*
Key Features
- True Factory OEM Overhaul: Sourced directly from B&T assembly lines to guarantee authentic geometric dimensions, reliable lockups, and strict Swiss quality management.
- Fully Ambidextrous Control: Features a mirrored dual-lever setup that allows tactical operations to comfortably drive the safety mechanism using either the left or right thumb.
- Steel-Reinforced Selector Axle: The main structural drum core is cut from hardened steel alloy to prevent shear wear and maintain precise internal sear engagement corners.
- High-Traction Contoured Paddles: Textured with non-slip linear index ribs across the polymer paddles to ensure reliable control activation in rain, mud, or sweat.
- Complete Detent Component Suite: Includes a fresh set of factory detents and high-memory springs to restore that snappy, clean click feeling between safety modes.
- Turn-Key Drop-In Architecture: Built to align perfectly inside the lower frame ports without requiring custom filing, heat fitting, or gunsmith modifications on the bench.
