Overview of the Wilson Combat AR-15 Barrel

  • Wilson Combat has been building AR-15 rifles for over two decades.  In this time they have learned a thing or two about what makes a quality stainless steel barrel.  With this knowledge and the desire to be an industry leader, the engineers at Wilson Combat set out to develop a line of AR-15 barrels that would deliver match grade accuracy, be highly reliable and give it’s users a long service life.


Starting with the Best

  • Wilson Combat chose to use 416R stainless steel as their starting material for this barrel.  This high-grade 416R steel was developed by Crucible with the specific intention of being used in rifle barrels. Chemically speaking, the main difference with 416R stainless steel is that is contains Molybdenum and also have a lower sulfur content than regular 416 stainless.  These changes can help to decrease the potential for catastrophic failure of your barrel.  Additionally, due to the lower sulfur content in the 416R steel, it may be better suited for sub freezing temperatures, as 416R steel is rated to temperatures as low at -40 degree Fahrenheit.


Attention to Detail

  • Wilson Combat is well known for making some of the highest quality 1911’s on the market.  One of the reasons why their pistols are so good is because they are very precise and pay attention to the minutia.  The employees at Wilson Combat have brought this same care and attention to detail to their line of Wilson AR-15 Barrels.  In addition to the craftsmanship displayed by the employees at Wilson Combat, it doesn’t hurt to have the top of the line machines as well.  These AR-15 barrels are formed on highly specialized, computer controlled equipment to an exacting list of technical specifications that Wilson Combat has developed.  After the machine work, the barrels then have their bore hand polished to ensure every part of the barrel is smoothed out.  The barrels are then finished with a precise, crisp CNC marking, a well as a precision muzzle crown and drilled gas port.



  • AR-15 barrels are available in a variety of different chamberings.  You may see AR-15’s chambered in .223 Remington, .223 Wylde, 5.56x45mm and a variety of other proprietary chamber dimensions.  Wilson chose to use the 5.56x45mm NATO specified chamber dimensions for this barrel.  This is the same chamber dimensions used in M16 barrels issued by the United States Military.  Although similar, it is not identical to the .223 Remington chamber dimensions.  One of the reasons for choosing the 5.56x45mm NATO chamber is that is can safely fire a variety of ammunition.  The 5.56x45mm chamber is equally suited to fire .223 Remington ammunition, or 5.56x45mm ammunition.  The inverse is not necessarily safe and generally advised against.


Twist Rate

  • This Wilson Combat Match Grade AR-15 Barrel utilizes a twist rate of 1:8.  This means that the barrel completes one rotation per every 8 inches is moves down the barrel.  The 1:8 twist rate has been found by several to adequately stabilize a large variety of projectiles.  While conventional 1:9 and 1:7 twist barrels were generally found to be better at the lower end and higher end of bullet weights, respectably, the 1:8 twist rate has generally been reported to stabilize a greater variety of different projectile weights adequately.
