"The Smith & Wesson M&P FPC Series Folding Carbine is a side-folding, pistol-caliber carbine that accepts M&P double-stack pistol magazines. The rifle comes with 3 magazines. The stock allows for storage of 2 magazines at the ready, eliminating the need for a mag carrier to mobilize with you. The barrel has a threaded muzzle so you can add a suppressor or muzzle device. Familiar and comfortable ergonomics are found on the M&P stylized grip, which also comes with 4 palm-swell inserts for the perfect, personalized fit. The aluminum receiver houses the steel bolt on this blowback-operated carbine rifle. The overall length of the FPC is 30.375"", and when folded, the carbine stows with a length of 16.375"". The side-folding design features a locking latch and does not interfere with mounted optics. The flat-faced trigger offers a clean, crisp break, and the magazine catch is reversible. The handguard has a Picatinny rail on top for optics or sights, while the rest of the rail is covered in M-LOK slots to attach accessories.
