Smith & Wesson M&P FPC Folding Carbine 16.25″

Smith & Wesson M&P FPC folding carbine. This compact, side-folding carbine is designed to provide a small footprint for transport and storage while retaining accessory mounting options for common range and training configurations.

The M&P FPC is intended as a compact carbine platform for range use, training, and situations where reduced folded length is desirable. It features a 16.25-inch threaded barrel, an M-LOK handguard for mounting accessories, and a Picatinny-style rail on top for optics. The folding stock and in-stock magazine storage help keep spare magazines onboard while minimizing overall length when stowed.

Compatibility & Intended Use

This platform accepts removable box magazines (three 20‑round magazines included) and provides a Picatinny-style top rail for mounting primary optics. The M-LOK handguard accepts M-LOK-compatible accessories (lights, grips, small rails). The threaded 1/2×28 muzzle allows installation of common 1/2×28-compatible muzzle devices. There are no factory iron sights installed; typical setups include a compact red-dot or low-power optic on the Picatinny rail with a small backup sight solution if desired.

The M&P FPC is suited to range and training use, scenarios requiring compact transport or stowage, and users wanting a folding carbine platform with on-board magazine storage and accessory mounting options.
