FN’s 502 Tactical is absolutely one of our favorite .22LR semi-auto pistols (see Jeremy’s very thorough review of the already optic-ready 502 Tactical here). Now FN’s offering an MRD-equipped, optic-ready version of its standard (non-tactical) 502 pistols as well. Here’s their press release . . .

Following the extremely successful launch of the optics-ready FN 502 Tactical, FN America, LLC is pleased to announce the expansion of its .22LR offerings with the all-new FN 502 MRD. The company released its first rimfire in 2021, the FN 502 Tactical, setting the bar high for future rimfire releases. However, none can best the fact that the FN 502 is the first purpose-built .22LR pistol designed for high round count training sessions while delivering maximum fun on the range.

“When we first started the development of the FN 502 platform, our goal was to up the ante for quality and versatility in a new rimfire pistol, applying our expertise in factory milled optics-ready slides, suppressor-ready barrels, and professional-quality triggers, some of the most sought after benefits in the FN 509 and FNX pistol product lines. We truly set a high bar for the industry,” said Chris Cole, Vice President of Sales for FN America, LLC. “The MRD model is the natural evolution of the FN 502 platform, allowing users to add a red dot, and make the most of the exceptional trigger. The MRD model offers another high-performance .22LR pistol for our customer base who value affordable quality in their rimfire pistols.”

The FN 502 MRD shares the same optics mounting system as the Tactical model that was inspired by the company’s patented Low-Profile Optics-Mounting System. Compatible with multiple micro red dot optics, users are able to swap out the MRD insert plates with integrated sights depending on their optic of choice, and be ready for a fun-filled range day within minutes.

The hammer-fired FN 502, with its best-in-class single-action trigger, performs like a robust-style target pistol, delivering fast, accurate rounds on target with more versatility than any other rimfire on the market. It offers superior ergonomics inspired by the grip profile of the FN 509 family of pistols and delivers the perfect balance between slide and frame along with fully ambidextrous controls.

Designed for maximum fun, FN’s hammer-fired .22 LR delivers more accuracy and versatility than any other rimfire handgun. Mounting a favorite red dot optic and cycling a wide range of .22 LR ammo makes a low-cost range day a high-end experience.

The FN 502 MRD ships with two 10-round flush-fit magazines along with the necessary plates to mount compatible micro red dot optics. Due to its similarity in muzzle and trigger guard dimensions to the FN 509, the FN 502 MRD will fit in most FN 509 holsters. To learn more about FN’s rimfire FN 502 family, please visit

  1. In my humble opinion the FN FNX handgun is the absolute best handgun ever produced. Decocker, safety and hammer fired! Shipped with three backstraps and three magazines! Very accurate too! What’s not to like?

  2. Looks like the perfect size, 7.6″ long, one inch longer than my Ruger SR22, and a 4″ barrel. But I’ve already modified my Ruger SR22 pistol to take a Holosun and added a 4″ threaded barrel to my SR22, so I don’t need to buy the FN, although I do like it, especially in FDE.

    I see on their website that FN also offers threaded barrel versions, but unfortunately the threaded versions have a 15-round capacity, so it’s unavailable to those of us who live behind the iron curtain in the People’s Republic of New Jersey (where even .22 rimfire pistols are “assault weapons” if they have a standard capacity mag!)
    I wonder if they’ll sell the 4.5″ threaded barrel separately so people stuck in states with the 10-round limit can upgrade to a threaded barrel?

    • “I wonder if they’ll sell the 4.5″ threaded barrel separately so people stuck in states with the 10-round limit can upgrade to a threaded barrel?”

      They, or another aftermarket company. Or, someone in a free state may arrange one for you. (No, I’m sorry, I’m not offering…)

  3. Worse yet is FN allowed the air soft company that makes these to use Zamak in the chassis. That means this is still a no go in the melt point states.

    • Melt laws are extra-ripe for repeal in the post ‘Bruen’ legal landscape.

      Have you considered donating to your state gun rights org to get those lawsuits rolling and become a part of the solution to the problem, ‘Joe’?

      Be a gun-rights hero! Think of the nubile young women who may throw themselves at your feet if you are the hero! 😉

  4. all .22 pistols and rifles are a go. can’t have too many. like ’em all except maybe (umarex?) mosquito.
    anything internally suppressed is superior.
    and no matter what you mention my response is cz kadett, das ende.

  5. Outstanding work, Mike. I applaud your efforts since I currently make more than $36,000 every month from just one straightforward web business. Even though these are the most fundamental internet operations tasks, you may start bs-06 making a respectable online income with as little as $29,000.
