FN America, LLC is releasing the new FN 15 Guardian rifle, chambered in 5.56 NATO. This new carbine weighs 6.6 pounds and employs a direct-impingement gas system.

 “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 features a 16-inch button-broached, hybrid-profile barrel with a 1:7-inch twist and is finished with the classic A2-style flash hider. The barrel of the Guardian is machined from 4150 chrome-moly vanadium steel that has been high-pressure tested (HPT), magnetic particle inspected (MPI) and certified, and nitrided for a durable, hardened surface.

The bolt carrier group is machined from 9310 alloy steel that has also been nitrided and HPT/MPI tested and certified for enhanced strength and durability, and the gas key has been sealed, torqued and staked. A mid-length gas system and low-profile gas block reside inside a 15-inch aluminum handguard, and the barrel is free floated barrel for enhanced accuracy. The handguard features a continuous Picatinny top rail and M-Lok slots on the sides and bottom, providing 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.”

The FN 15 Guardian has a suggested retail price of $999 and ships with one 30-round magazine. For more information on this rifle or other products from FN America, please visit
