About This Firearm
The FN 15 TAC3 is a mid-length semi-automatic AR-15 in 5.56 NATO built for duty and defensive use. It has an MSRP of $1,889. Its safety selector and charging handle are both Radian parts, so the rifle runs from either shoulder with no parts bought.
It comes with one 30-round FN polymer magazine and a six-position buttstock of FN's own snag-free design with a QD socket built in. The Talon selector takes long or short levers and reverses, and the Raptor-LT charging handle has a latch on each side. No sights are fitted. The trigger is mil-spec, so a two-stage unit is a drop-in change, and the A2-style flash hider sits on a thread with no pitch marked, so a suppressor mount means measuring the muzzle first.
If you're cross-shopping, an FN 15 Guardian has an MSRP of $999 on the same 1:7 twist and a nitride HBAR barrel, with mil-spec controls and a muzzle FN states as 1/2x28, and it carries 0.40 lbs less. A BCM RECCE-16 weighs 6.10 lbs on a chrome-lined government-profile barrel, 0.90 lbs under the TAC3. The TAC3's extra weight comes from the Radian controls and the Hodge handguard, which the other two do not have.

Strengths & Limitations
- The bolt is HPT and MPI-tested Carpenter 158 steel in an M16-style 8620 carrier, with the gas key staked to mil-spec.
- The gas block is pinned to the barrel, so it cannot shift on the gas port, and an H buffer is fitted in place of the lighter carbine weight.
- FN sells the TAC3 in black anodize and in factory FDE and gray Cerakote.
- The Cerakote finishes carry a different MSRP from the black rifle, so the price depends on the color.
- No sights come with it and the gas block is low profile, so a backup front sight has to be a rail-mounted one.
- One magazine is in the box, so magazines are an immediate purchase at this price.

Frequently Asked Questions
What magazines does it take?
Any standard AR-15 magazine. The FN magazine supplied with it is a polymer STANAG-pattern body, stippled in the mold like the grip.
Is the barrel free-floated?
Yes. The Hodge Defense wedge lock handguard mounts on its own proprietary barrel nut and nothing touches the barrel ahead of the gas block. FN credits the anti-rotation interface with minimal deflection under load.
Will a Picatinny bipod fit the handguard?
Not directly. The underside is M-LOK at 6 o'clock with no rail section, so a Picatinny bipod needs an M-LOK adapter.
