The Science of Torque: Why Precision Matters for Your AR-15

In the world of firearms, "good enough" is rarely good enough, especially when it comes to the mechanical connections that define an AR-15's performance and safety. The concept of torque, a twisting force that causes rotation, is critical for numerous components, but none more so than the barrel nut.

Understanding Barrel Nut Torque Specifications:
The standard torque specification for an AR-15 barrel nut typically falls within a range of 30 to 80 foot-pounds (ft-lbs). This broad range is intentional, allowing armorers to align the gas tube with the gas tube hole in the upper receiver, which requires the barrel nut to be tightened until the next slot aligns. However, remaining within this specific range is paramount.

• Under-torqued: An under-torqued barrel nut can lead to a loose barrel, which directly impacts accuracy, causing inconsistent point of impact. It can also allow the gas tube to shift, leading to cycling issues (failures to feed, extract, or eject). In extreme cases, a very loose barrel nut could potentially allow the barrel to rotate or even detach, creating a dangerous situation.
• Over-torqued: Over-torquing is equally detrimental. It can permanently deform or stretch the threads on the barrel extension, the upper receiver, or the barrel nut itself, making future disassembly difficult or impossible without specialized tools and risking damage to the receiver. Over-torquing can also induce stress into the barrel, potentially affecting its harmonic characteristics and, consequently, its accuracy. Furthermore, it can make gas tube alignment more challenging, potentially requiring excessive force that could damage the gas tube or gas key.
