Cold Hammer Forging of barrels has been known for decades to produce the most accurate, longest lasting rifle barrels obtainable. The Cold Hammer Forging of barrels is accomplished through intense hydraulic pressure applied at opposing angles by carbide steel hammers. During the hammering process, a mandrel is inserted into the bore while the carbide steel hammers shape the barrel around the mandrel creating the chamber, the lands, and the grooves. In addition to the aforementioned benefits, the Cold Hammer Forging process creates a defect free bore and the most consistent chamber possible.

They are all MP tested on-site and will prove themselves to be more accurate and last longer than a barrel that has cut or button rifling.

  1. Great fit for 62gr, 55gr not so much.

    Posted by SGT. Snuffy, Muldoon on 22nd Nov 2012

    I put one on my last build and had no issues with fit or finish, everything went together the first time. I have never experineced a failure in locking, chambering, and un-locking. To a bit to find the right Ammo, I was not getting good results with federals XM193. XM855 was much better and black hills 62gr could be sub-moa with a better operator.

  2. Perfect barrel

    Posted by Unknown on 31st May 2012

    FN Manufacturing makes the best barrels on the market. This barrel is durable enough to put thousands of rounds through on automatic fire without cleaning and have no issues. This barrel was designed for and is used on, the M249 squad automatic weapon, beltfed light machine gun. It has been milled down to the standard M4 profile, but this does not effect the funtion at all. This barrel is worth twice the price I paid for it here at surplus.

  3. Awesome barrel

    Posted by Unknown on 23rd Feb 2012

    This is by far the best barrel on the market. It is an M249 SAW barrel, lathed down to an M4 profile. It is designed from start to finish to take a beating. It is strong enough to handle consistant automatic fire, but light enough to manuver well in CQB enviornments. The price is the best anywhere, and the 1:7 twist is precise enough for open sights at 800yrds. Shoots better than I ever have.
