Smith & Wesson M&P FPC 22 LR Folding Carbine 16.25″ Threaded (#14171)

Compact, Folding Rimfire Carbine with M-LOK and Mag Storage

The Smith & Wesson M&P FPC in .22 Long Rifle brings precision rimfire performance in a folding, ultra-compact package. Its 16.25″ threaded barrel (1/2×28) is suppressor-ready, and the folding stock allows optic preservation and easy transport. With three included 20-round magazines stored in the stock, and a capacity of 20+1, you’ve got 60+1 rounds onboard before reloading.

Built on the proven M&P platform, this carbine features the same ergonomic pistol grip and flat-face trigger that many shooters already know and trust. The forend includes M-LOK slots and a Picatinny rail up top for accessories and optics. Maintenance is quick—field-stripping requires no tools other than the included grip tool. Controls are ambidextrous or reversible to suit both lefties and righties.
