We ran the FN 15 Patrol Carbine with M-Lok furniture through its paces. FN first started manufacturing the FN 15 in the early 2010s and has continued to add variants to this platform ever since. Specifically manufactured with the needs of law enforcement in mind, they emphasize reliability and durability.
We had the pleasure of working with the Patrol Carbine chambered in 5.56x45 NATO. There is nothing epic about the carbine except that it is a great quality firearm manufactured by a quality company. I do love the AR platform, and I like this carbine for its size and weight. This carbine has a 16-inch barrel length with an overall length of approximately 31.9 inches.
The overall empty weight is 6.5 pounds. The barrel is 4140 alloy steel, chrome-moly vanadium steel, and has rifling with a 1:7 right-hand twist. The rifling process is button cut. The robust barrel is great for heavy use as all well as maintaining accuracy. One of FN’s legacies is its excellent barrels.
Overall, this is an easily managed and manipulated carbine on the range or in the field. I’ve listed some additional specs below:
