Cold Hammer Forged Barrel Basics
Cold Hammer Forged is a term you may have heard when it comes to AR barrels, but why is it something worth considering? First off, it's important to know that choosing an AR-15 barrel for you next build is perhaps the defining moment for your firearm. Determining what kind of barrel you will have dictates just what sort of rifle you are building, and for what reason.
As to why choose a cold hammer forged barrel? When it comes to long life and durability, many shooters believe that a cold hammer forged barrel is superior to barrels that are button-cut. The thought is that for a rifle that will be receiving a high volume of fire, getting hot, and having a large round count, having a cold hammer forged barrel is an advantage in that the hammer-forging process creates a barrel that can better withstand heat, leading to a longer service life. With barrels that are not cold hammer forged, under constant heat and stress, they can be more prone to throat erosion, gas port erosion. As a result, their lifespan is not as long.
Availability of Cold Hammer Forged Barrels
While the cold hammer forging of barrels is actually less expensive due to their high productivity, the cost of the machines needed to do this sort of forging are quite high. While these machines are popular in Europe, they are not as prevalent in the United States. Many manufacturers decide to forgo costs associated with cold hammer forged barrels and go with button-cut barrels.
It’s important to know that for most shooters, these button-cut barrels are perfectly adequate. Many of our favorite builds feature barrels from top quality manufacturers like Faxon and Ballistic Advantage that are not cold hammer forged. That said, if we're building a gun that we know is going to be a workhorse at the range, or is going to be used for 2-day to week long classes where we are ripping off long strings of fire, and going thru mag after mag running drills, then that's when a cold hammer forged barrel starts to make a lot of sense.
The Process of Creating a Cold Hammer Forged Barrel
Without diving into complex metallurgy, it's worth noting that the cold hammer forging process happens via hydraulic pressure at opposing angles by carbide or hardened steel hammers. It's not actually "cold" but more like room temperature. While the hammering occurs, a mandrel is inserted into the bore while the hammers shape the barrel around the mandrel creating the chamber, the lands, and the grooves. Due to this unique process, the bore's surface is quite smooth, which gives the projectile a smoother path as it travels through the barrel. This smoothness also helps the barrel be quite accurate.
