B&T USA Magazine Release Kit - Factory OEM Fully Ambidextrous Assembly, Hardened Tool Steel & Premium Composite, Black - BT-KIT0006
Product Description
Maintaining or refreshing the control architecture of a high-performance submachine gun or pistol-caliber carbine requires factory-original replacement parts built to Swiss tolerances. Worn or loose magazine catches can fail to retain fully loaded magazines during aggressive reloads, causing feeding errors or complete drop drop-outs on your bench. The **B&T USA® Magazine Release Kit for APC9/45 (BT-KIT0006)** completely flatlines this reliability bottleneck, providing a full, factory-calibrated ambidextrous catch replacement overhaul system.
Proudly engineered by Brügger & Thomet to professional duty standards, this master kit includes the primary multi-axis magazine release bar, the opposite-side release pad button button interface, and a pair of factory-rated compression return springs. The core structural catch post is precision CNC-machined from **hardened carbon steel alloy**, treated with a matte black anti-friction phosphate layer to survive severe range friction. The dual thumb pads are formed from B&T's proprietary **high-impact polymer compound**, complete with deep linear indexing ribs to guarantee a positive, non-slip tactical purchase even when running slick gloves.
Engineered to slide natively into the factory frame tracks of your lower receiver housing, this turn-key armorer component refresh package ensures clean magazine drops and crisp lockups straight from your workbench.
*Armorer Bench Notes & Real-World Receiver Staging Guidance: The B&T BT-KIT0006 package arrives workspace ready, containing 1x main ambidextrous magazine catch bar assembly, 1x right-side release pad button insert, and 2x precise factory-coiled coil return springs. PROPRIETARY PLATFORM CHASSIS INTERFACE MATRIX: This overhaul array is engineered natively, strictly, and exclusively to service **standard B&T factory lower receivers configured for proprietary B&T polymer magazines**. *Host Sub-Gun Checklist:* It perfectly overhauls the **B&T APC9, APC45, GHM9, and SPC9 sub-guns / PCC variants** using original B&T magazines on your bench. System Receiver Footprint Exclusion: This kit **will not fit B&T lower receivers configured to accept Glock® or Sig Sauer® P320 magazine styles**, as those variants deploy entirely different retention jaw paths. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host firearm platform is completely clear of live ammunition, the magazine is removed, and the chamber is safe. 2. Field strip the weapon to isolate the lower receiver frame block onto your workspace padding. 3. Use a micro drift punch tool to compress the internal cross-retaining pin holding the right-side mag release pad in place. 4. Carefully slide the legacy right-side button off the cross-shaft, capturing the twin tension springs as they vent out of the receiver pocket. 5. Pull the main left-side release bar straight out of the frame chassis tracks. 6. Clean the guide channels thoroughly with a nylon brush to remove carbon build-up. 7. Grease the smooth shaft channels lightly, insert the new BT-KIT0006 main catch bar, seat the dual return springs into their alignment holes, compress the system from the left flank, and slide the new right-side button home until it clicks securely into its mechanical lock groove downrange.*
