Description
Smith & Wesson took the folding carbine concept that made the original FPC such a hit and scaled it down to .22 LR, and the result is a seriously fun little rifle. The side-folding design cuts the overall length from about 30.4 inches down to roughly 16.4 inches, small enough to tuck into a backpack, range bag, or behind the seat. Better yet, because it folds sideways instead of breaking over the top, whatever optic you mount on the Picatinny rail stays put and holds zero. Unfold it, snap it into battery, and you are back in business.
Pistol Ergonomics in a Rimfire Carbine
If you have spent time behind an M&P pistol, this carbine will feel like home. The grip and flat-face trigger are pulled straight from the M&P handgun line, and interchangeable backstraps let you dial in the fit for your hand. The magazine catch is reversible for lefties, a crossbolt safety keeps things simple, and the buffer tube style stock hides a clever trick: storage slots for two spare magazines with quick-release tabs, so your reloads travel with the gun.
Suppressor-Ready and Built for the Range
The 16.25 inch barrel wears 1/2×28 threads under a thread protector, which is the standard pattern for rimfire cans, and quiet .22 LR through a suppressed carbine is about as pleasant as shooting gets. M-LOK slots along the forend handle lights, hand stops, or a bipod, and the full-length top rail gives you plenty of real estate for a red dot or scope since there are no factory irons. At right around 5 pounds, it is light enough for new marksmen and small-statured folks to run comfortably all day.
Why the M&P FPC 22LR Earns a Spot
This version ships with three 10-round magazines, and the blowback action runs happily on quality high-velocity ammo. Between the cheap ammo, mild report, zero recoil, and grab-and-go portability, this is the kind of gun that turns a quick range trip into an all-afternoon plinking session. Great trainer, great camp rifle, and a genuinely good time.

Frequently Asked Questions
Does the M&P FPC 22LR come with sights?
No, it ships without iron sights. The receiver has a Picatinny rail on top, so plan on adding a red dot or a compact scope. A budget rimfire red dot pairs really well with this platform and keeps the package light.
Will mounting an optic cause problems when the carbine folds?
Not at all, and that is one of the smartest parts of the design. The FPC folds from the side rather than over the top, so your optic never contacts anything and your zero stays intact. Fold it, stow it, unfold it, and you are ready to shoot.
Can I put a suppressor on the M&P FPC 22LR?
Yes, the 16.25 inch barrel is threaded 1/2×28, which is the standard pattern for nearly every rimfire suppressor on the market. A thread protector comes installed from the factory. Suppressed .22 LR out of a 16 inch barrel is impressively quiet, especially with subsonic ammo.
What magazines does this version of the FPC use?
This model ships with three 10-round magazines that feed through the grip, just like a pistol. The stock has built-in storage slots with quick-release tabs that hold two spares onboard, so all three mags travel with the gun. It runs on S&W's M&P 22-pattern rimfire magazines rather than centerfire pistol mags.
