Product Description

What's in the Box

  • FN 15 Guardian rifle
  • One 30-round FN polymer magazine
  • Owner's manual

The FN 15 Guardian is a 5.56 NATO AR-15 with a 16-inch barrel, a mid-length gas system and a 15-inch free-float M-LOK handguard. For range days, it gives you an adjustable fit and room to add your choice of compatible sights or optics. This black model comes with one 30-round FN polymer magazine.

16-Inch Nitride-Finished Barrel

FN makes the Guardian's barrel from 4150 chrome-moly vanadium steel and applies a nitride finish for corrosion resistance. It has a 1:7 right-hand twist and an A2-style flash hider. A mid-length gas system and low-profile gas block sit beneath the handguard.

Full-Length Handguard with M-LOK Slots

The 15-inch aluminum handguard gives you room to find a comfortable support-hand position. Its 24 M-LOK slots run along both sides and the bottom, with a continuous Picatinny rail on top for compatible sights and optics. The free-float design keeps the handguard from contacting the barrel.

Adjustable Stock and Textured Grip

FN's six-position stock lets you adjust the length of pull and includes several sling attachment points. The pistol grip has molded-in texture, while the charging handle and safety selector follow the familiar AR-15 layout. The Guardian also has a single-stage mil-spec trigger and a forged 7075 aluminum lower receiver.

Shop the FN 15 Guardian at Sportsman's Outdoor Superstore.
