11.5" AR Barrel by Spikes Tactical

The Spikes Tactical CHF Barrel is extremely durable. Its projected service life is upwards of 20,000 fired rounds. This Spike’s Tactical 11.5” CHF barrel is designed with the Mil-Spec standards for the M249 S.A.W. in mind but in a smaller, lighter package intended for the AR-15. Each one of these barrels is hardened by the Cold Hammer forging Process which involves a long process of hammer forging the blank barrel on a rifled mandrel. These particular barrels are chambered to 5.55 NATO and rifled with a 1 in 7 twist. Barrel blanks are internally lined with a hard chrome coating almost double the thickness of that found in M4 Mil-Spec barrels, as required by the Mil-Spec standards for the M249 SAW.

Lightweight AR-15 Barrel

To create the final product, the Spikes Tactical CHF Barrel is precision turned until it’s sized down to a lightweight profile. In the end, it weighs in at 17.5 ounces, including a Mil-Spec M4 barrel extension on the 11.5” CHF barrel. Each barrel is precision threaded at the muzzle so that the ½ x 28 threads are perfectly concentric with the bore. Attention to detail makes for a superior product. This barrel will not only outlast much of the competition, it will do so with accuracy that’s hard to beat.

The Spike's Tactical 11.5" 5.56 FN Cold Hammer Forged (CHF) Carbine-Length Barrel features a .625 inch gas block seat with the appropriate size gas port. There is no front sight base on these barrels and they feature a sleek Mil-Spec Phosphate finish.
