Modular 7075-aluminum selector kit for B&T APC, GHM, and SPC lowers with long, short, and delete-side lever options.

+12 more
HBI's modular selector kit replaces the B&T selector shaft and both thumb levers, letting the shooter choose a long lever, short lever, or safety-delete cap on either side. That flexibility matters on the compact GHM9 and SPC9 because the factory right-side lever can rub the trigger finger while a short support-side lever still preserves ambidextrous access.
The shaft and levers are machined from 7075 aluminum. HBI lists compatibility across the B&T APC, GHM, and SPC model families. The manufacturer does not guarantee operation with aftermarket AR-pattern triggers and warns that fit can vary with aftermarket aluminum lowers, so those combinations need to be confirmed before ordering.
