FN America, LLC is pleased to announce the launch of the FN 15 Guardian, the newest addition to the company’s modern sporting rifle product line. This carbine is derived from FN’s battle-proven blueprint, delivering FN reliability to all sport shooters and personal protectors who value affordable quality. Chambered in 5.56 and weighing in at 6.6 pounds, the direct-impingement rifle is outfitted with a 15-inch M-LOK free-floated aluminum handguard and MIL-B-11595 CMV barrel. These premium, FN factory-installed upgrades produce tack-driving accuracy, add customization options, and improve handling.

“High quality and affordability don’t typically go hand-in-hand, but today’s buyer deserves to have the best of both worlds when they’re investing their hard-earned money into a rifle. That’s why we chose to develop the FN 15 Guardian,” said Chris Cole, Vice President of Sales and Marketing for FN America, LLC. “As a leader in barrel manufacturing, FN has some of the most sought-after and high-quality AR-style rifles in the industry. For the release of the FN 15 Guardian, we focused our energy into creating an extremely high-value, reliable carbine that carries the legacy of our manufacturing expertise to new FN customers.”

The FN 15 Guardian is chambered in 5.56x45mm and features a 16-inch button-broached, hybrid-profile barrel with 1:7 twist finished with the classic A2-style flash hider that reduces visible flash during fire. The barrel is machined from 4150 chrome-moly vanadium steel that has been high-pressure tested (HPT), magnetic particle inspected (MPI) and certified, and nitrided to deliver an extremely durable, hardened surface finish that provides corrosion resistance. Paired with the free-floated handguard, accuracy potential is greatly improved, the Guardian is able to shoot sub-minute groups with match-grade factory ammunition to extend target engagement ranges.

The bolt carrier group is machined from 9310 alloy steel that has also been nitrided and HP/MPI tested and certified for enhanced strength and durability, and the gas key has been sealed, torqued and staked. The mid-length gas system and low-profile gas block work seamlessly together to ensure reliable operation, while reducing felt recoil.

The lightweight, 15-inch aluminum handguard attaches to the upper receiver via a robust mounting system that securely fastens to the receiver and enables a fully free floated barrel for enhanced accuracy. The handguard features a continuous top rail and 24 M-LOK slots at 3, 6 and 9 o’clock positions, providing ample space for mounting sights, optics and other accessories.

“When we created the specification for the FN 15 Guardian, our focus was on perfecting the foundation of the rifle to ensure the high standards for FN quality remained, cutting corners to reduce the purchase price was not an option, our customers expect more from our brand and we have to deliver on that trust.” said Scott Vilardi, Senior Product Manager for Law Enforcement and Commercial Carbines. “When you handle our newest carbine at the gun counter and shoot it on the range, you’ll notice the premium fit and finish stands out at this price tier. We’ve paid special attention to the core components to overdeliver on accuracy potential, ergonomics and fast-handling capability. With the new Guardian, FN customers have a dependable and high-quality carbine that’s ready to perform right out of the box and can be easily customized with most AR-pattern components.”

For a streamlined look and feel, as well as reduced snag points, the slick-sided upper receiver eliminates the forward assist while still featuring a brass deflector and ejection port cover to keep spent brass from ejecting back toward the user as well as dirt and debris from entering the moving parts group of the rifle. Additionally, the upper receiver features a tried-and-true MIL-SPEC charging handle and safety selector lever for ease of operation.

The lower receiver is machined from a 7075-aluminum forging that has been hard coat anodized for premium surface finish and durability. The carbine is complete with a single-stage MIL-SPEC trigger that ranges from 4.75 – 7.5 pounds along with FN’s custom-designed 30-round magazine and furniture, developed for improved ergonomics and handling.

The custom furniture package, also offered as individual accessories, include the 30-round magazine with in-mold stippled grip texture, polymer matrix construction and anti-tilt follower. A six-position glass-filled polymer stock has three sling attachment points and an anti-snag latch for a tight lockup to the buffer tube, eliminating rattle. The pistol grip is molded with the same durable, polymer matrix material, an optimal 19.5-degree grip angle and in-mold stippled texture to improve control and handling.

The FN 15 Guardian has a suggested retail price of $999.00 and ships with one 30-round magazine packaged in a unique branded cardboard box with owner’s manual. In addition to the Guardian, the FN 15 series of modern sporting rifles include the FN 15 TAC3 and DMR3, along with a complete line of accessories like upper and lower receivers, barrels, furniture and magazines.

  1. If FN approaching the upper ranges of “budget” AR? Not a complaint or a criticism I am just amazed to see a FN product this low.

  2. Although the rifle is nice, price is good it is not my type, all of mine have A1 stocks, 7.25″ M-lok handguards, A2 style detach carry handles with night sights, Sadlak rail height clamp type gas blocks, detach front night sights, etc. During the rush Criterion had backorders out the ears which forced a switch to FN fully chrome lined carbine barrels. FN performed well enough to make them a go to for any furture carbine builds.

  3. I still don’t understand why you wouldn’t just invest in building one. For the price you can get so much more. Even if you buy a complete upper/lower and then add the rest. Complete uppers/lowers from Aero are like $800 or less combined. Add the rest yourself and it’s custom to you with room for a better budget on optics.

    • Sometimes tax and shipping drives the price point above a similar budget offering (especially if one can purchase most of it in a sales tax exempt state while traveling) but generally I would agree it makes more sense to put one together especially when you need a permit for a semi auto version but are totally good to go building a bolt action version from a lower.

  4. I do not recall which magazine it was (G&A, SWAT, Shooting Times) but they did a comparison of rifles and the how and whys some were cheaper than others.
    The ones closest to MIL-SPEC cost the most.
    The cheaper ones, they cut corners to reduce the price. They still work fine. They were just not MIL-SPEC.

  5. The fact it doesn’t have an FA and they’re saying it’s a defensive gun is an interesting data point. I’m sure there’s cost implications too, but it says something about how much of an appendix they probably are.

    • most people dont understand the need for for the fa
      because most people never needed to use the fa
      ive had to use it two different times
      since then
      ill never buy another upper that doesnt have one

  6. Another AR. Well, why not? At least it’s built by FN. Reasonable price too. I’ve owned a few of their Hi-Powers. Still have one. A couple of their FALs. One Superpossed. All excellent firearms. If I wanted another AR I would look at this.

  7. Other than its lower (for FN anyway) price point, how is this any different than any other AR out there?
    Someone commented about building your own, which I have done. The real cost killer in California is the extra costs associated with getting the lower. Even stripped, there is sales tax and the dreaded DROS add on charge of $37 or so, plus shipping. Suddenly that $70 lower is doubled in price if you buy it off the internet.

  8. I’ll buy it – one can never have too many ARs…or bump stocks…or Glock switches.
    But no RDS – the government uses them to see what you are shooting.

  9. I do believe I’ll run out and buy one of these. The gotta-have-it selling point for me is the “unique branded cardboard box.”

    </sarc> if it isn’t obvious

  10. FN 15 Guardian Carbine is a reliable and versatile rifle designed to meet the needs of law enforcement and civilian users who require a high-quality firearm for personal protection or sporting purposes.
