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 chambered in 5.7x28mm.

Introduced as an expansion of Smith & Wesson’s FPC series, Model 14169 combines the compact folding architecture of the platform with magazine compatibility shared with the M&P 5.7 pistol. The standard-capacity configuration is associated with UPC 022188903829.

Smith & Wesson M&P FPC 5.7×28 Overview

The FPC 5.7 folds horizontally at the center of the firearm, allowing the carbine to form a compact package without folding the stock itself.

Its design incorporates an M-LOK handguard, continuous upper Picatinny rail, flat-face trigger and polymer stock with storage for two spare magazines.

The standard Model 14169 includes three 22-round magazines.

FPC 5.7×28 Chambering

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

Model 14169 is supplied with three 22-round magazines, while the separate compliant Model 14170 uses three 10-round magazines.

Therefore, magazine capacity and model number should be checked carefully when creating inventory records.

16.25-Inch Threaded Barrel

Smith & Wesson equips the FPC 5.7 with a 16.25-inch barrel.

The muzzle is factory threaded 1/2×28 and supplied with a thread protector.

The carbine measures approximately 30⅜ inches overall when unfolded and approximately 16⅜ inches when folded, making its compact folded length one of the platform’s primary identifying characteristics.

Folding Design, Rail and Controls

The handguard includes M-LOK accessory slots and an upper Picatinny rail for compatible sighting equipment.

Other factory features include an M&P-style pistol grip, reversible magazine catch, cross-bolt safety, integrated recoil buffer and multiple QD sling-mounting points.

The stock also stores two spare magazines, allowing all three factory magazines to remain with the carbine.
