The National Firearms Act regulates the configurations of some firearms assembled with barrels under 16” long. Know the NFA laws in your state before purchasing this item.


These amazing cold hammer forged barrels are extremely durable with a 20,000+ round service life. These lightweight 14.5" barrels weigh 22.0 oz with M4 barrel extension and no front sight base. The barrels have a .750" gas block seat with a properly sized gas port, and the muzzle is threaded perfectly concentric to the bore with 1/2x28 threads. These barrels are made to military specifications for the M249 SAW. The cold hammer forging process work-hardens the steel around a rifled mandrel, which creates the lands and grooves. These barrels are chambered in 5.56 NATO, with a 1:7 twist rate. The barrel blanks are the correct certified CMV material and they are also hard chrome lined to the M249 SAW MIL-SPEC, which is almost twice as thick as the hard chrome on a MIL-SPEC M4. The result is a rifle that can be run hard day after day! Each barrel is high pressure tested and magnetic particle inspected. They have M4 barrel extensions, and are phosphate finished on the outside (under the front sight base as well).

ST FN CHF 14.5 Barrel - Amazing

by

I used this barrel in my latest 14.5 build with the Spike's Tactical dynacomp as the muzzle device. Just over 16" and the barrel performs so well. Having alot of fun with this one. Groups at 1" or less at 50yds with irons. Easy install, great barrel - its cold hammer forged - and the same one used in the M249 SAW. Built to last - perfect service from Primary Arms. Thanks Spike's Tactical and PA!

Fast shipping, great service overall.Have yet to build the rifle and use it, but it looks great and was received quickly. Will definitely do business with PA again.

Spikes/FN 14.5 CHF Barrel

by

These barrels are amazingly well made and shoot beautifully. Can easily hold the 10-ring on an SR-1 target at 100 yards using 55 grain FMJ hand loads. Shoots many brands of factory XM-193 type ammo equally well although some use better projectiles. Much better groups with 69 grain match grade hand loads. Had a Voodoo Tactical Manimal FH pinned and welded to bring the barrel to 16 1/8". Gas blocks slide right over the smaller dia FH so it can be installed later or removed for service. The 14 1/2 Spikes/FN barrel feels much more compact than one might expect compared to a 16" barrel plus a FH. A YHM set screw gas block mounted under a free float rail rounds out the upper build. The barrel is a real military grade part and should last for many years with an estimated service life of 20K rounds. The only downside is the price although they do go on sale a couple of times a year. But the Spikes/FN CHF will probably outlast 2 standard grade barrels.

Accurate but slight issue

by -

I am a huge spikes tatical fan but with this barrel the M4 feed ramps did not line up perfectly. this is with a spikes upper reciever. there was a small lip that your fingernal would catch on. Rifle functioned flawless but I still was not happy with a lip on one of my feedramps so I had to take a dremel to a brand new barrel. Not something that should happen using quality, matching brand parts. It was a very quick fix easier than returning it. I'm sure PA would have taken care of me. Strong note accuracy is sub moa :-)

Great Quality and Accuracy!

I finally shot this barrel last week. I had shots touching at 50 yards and 1/2-3/4 inch groups at 100 yards if I did my part. It assembled with a DSA stripped upper perfectly. Very nice compromise between a govt profile and a lightweight. I am very happy with it. I will write another review at 500 rounds.

Still a Great Barrel!

I said I would write another review at 500 rounds. Now at around 800 rounds with this barrel. This barrel assembled with various manufacturer parts shoots well. I have not used any match grade ammo and currently using Federal 55gr 5.56 200 round packs. I shoot on a bench without bags or rail so group size is dependent on my abilities too. It shoots 1-1.5" at 100y. I shoot at 18" plates at 300y and 20" plates at 550y no problem. I am sure the barrel is capable of better than what I can do. I have not had any malfunctions or problems with this barrel. Quality Barrel!
