Smith & Wesson M&P FPC 5.7×28 16.25-Inch Carbine

The Smith & Wesson M&P FPC 5.7×28 16.25-Inch is a semi-automatic folding carbine introduced for 2026.

Model 14169 combines Smith & Wesson’s FPC folding architecture with the 5.7x28mm cartridge and magazine compatibility shared with the M&P 5.7 pistol. Its factory configuration includes a 16.25-inch threaded barrel, blowback action, integrated recoil-buffer system, flat-face trigger and polymer stock with spare-magazine storage.

Smith & Wesson M&P FPC 5.7×28 Overview

The 5.7x28mm model expands the FPC family alongside earlier 9mm, .40 S&W, 10mm and .22 LR configurations.

The carbine folds horizontally at the center of the firearm rather than folding the stock itself. This layout allows a compatible top-mounted optic to remain attached when the rifle is folded.

The folding mechanism also incorporates a locking latch that secures the firearm in its compact configuration.

FPC 5.7×28 Chambering

The carbine is chambered in 5.7x28mm and uses the same magazine pattern as Smith & Wesson’s M&P 5.7 pistol.

Standard Model 14169 ships with three 22-round magazines and a proprietary loading tool. Two spare magazines can be stored inside the polymer stock.

Smith & Wesson also offers a compliant Model 14170 supplied with three 10-round magazines, so the two configurations should remain separate in WooCommerce.

16.25-Inch Threaded Barrel

Smith & Wesson specifies a 16.25-inch barrel with a factory-threaded 1/2×28 muzzle.

The standard configuration also includes a thread protector.

Overall length is approximately 30⅜ inches, while folded length is approximately 16⅜ inches. These dimensions are among the clearest identifying characteristics of the FPC platform.

M-LOK Handguard and Controls

The handguard incorporates M-LOK slots together with an upper Picatinny rail.

Smith & Wesson pairs this arrangement with an M&P 5.7-style pistol grip, flat-face trigger, reversible magazine catch and cross-bolt safety.

The 5.7 model also incorporates QD sling-mounting points on the stock and sides of the handguard.
