The Fierce Firearms F-15 Sidewinder is a serious AR-15 platform rifle made for serious precision shooting. If you demand more than just going to the range and going pew pew, this rifle is worth a look.
Fierce Firearms is known for seriously accurate rifles, guaranteeing ½ MOA accuracy, with – of course – appropriate ammunition selection and (also obviously, but they don’t say it) if the shooter does their job. A rifle doesn’t go out the door unless it groups three shots in less than ½” at 100 yards, and you get the target to prove it with purchase.
You pay for the privilege, of course, but the quality and precision for the price paid is outstanding. Heretofore, their specialty has been bolt-action rifles, especially for the long-range precision hunting crowd, but Fierce has now added an AR-platform rifle to their product lineup.

The Fierce F-15 Sidewinder is made in .223 Wylde (meaning it can chamber both .223 Remington and 5.56 NATO) or in .22 Nosler, whichever is your preference. You also have your choice of 16-inch match-grade barrel, either a hand-lapped stainless or a C3 Carbon Barrel.
The action includes a Velocity Precision trigger and ambidextrous controls. The pistol grip is carbon fiber, as is the M-LOK handguard. The receiver and handguard have a full-length aluminum Picatinny rail for mounting optics (or iron sights, if one were so inclined) and the receiver is streamlined to reduce potential snags.
The Fierce F-15 Sidewinder is a side-charger, so the charging handle is directly mounted to the bolt rather than being located at the back of the receiver. Fierce also omits the forward assist, which is kind of a breath of fresh air.
The carbon fiber components reduce the Sidewinder’s weight to 6.2 pounds in .22 Nosler or 5.9 pounds in .223 Wylde.
Again, you’ll pay for the privilege; MSRP is $2595 for the stainless barrel, and $2995 for the C3 model. However, you’re paying for quality. Fierce Firearms’ bolt-action rifles are of superb quality, and their F-15 Sidewinder AR looks to be well. Some people would rather invest in one quality rifle than go through five or six cheap ones. This one would certainly be a good one to invest in.
