The JL Billet Reaper PDW Chassis with Brace for the Sig Sauer P365 (brand part no. JLB-365-RPR) transforms the P365’s fire control unit into a personal defense weapon-style chassis with an integrated stabilizing brace, built from machined aluminum instead of the factory polymer frame. JL Billet designs the Reaper chassis to accept the P365’s factory fire control unit directly, giving owners a fundamentally different platform for stability and control while keeping the same trigger group and magazine compatibility. The brace adds a forearm attachment point for improved one-handed stability, a popular configuration for shooters building a compact PDW-style setup around their existing P365 internals.
