Cobalt Kinetics
A quality gas block is fundamental to a reliable, tuned AR-platform rifle—and the Cobalt Kinetics CKGB/NA750 gas block is engineered for shooters who demand precision and durability. Built from black nitride steel with a .750" bore diameter, this gas block suits standard rifle-length AR-15 and AR-10 builds where gas port sizing and barrel profile call for this common dimension. Whether you're assembling a precision long-range rig, a competition carbine, or a dependable hunting platform, a properly sized gas block ensures consistent cycling and minimal carrier tilt.
Cobalt Kinetics brings a reputation for attention to detail in the AR ecosystem. This gas block's black nitride finish resists corrosion and offers a refined, professional appearance on the barrel. The .750" specification is a workhorse size across a wide range of mid-length and rifle-length builds, making this block a practical choice for builders who know their barrel profile or are refreshing an existing system.
Installation and tuning depend on your specific rifle setup, barrel length, and intended use—factors that make consulting your builder's manual or a trusted gunsmith worth the time. Once properly seated and aligned, a solid gas block like this one handles the regulating workload that keeps your action running clean and on target.

The .750" bore diameter is a standard size for many AR barrels, but you'll need to verify your specific barrel's gas port diameter and exterior profile. Consult your barrel manufacturer's specs or have a gunsmith confirm compatibility before purchase.
Gas blocks are sized to match the external diameter of your barrel at the gas port location. The .750" dimension fits barrels with that specific outside diameter in the gas block zone. Using the correct size ensures proper alignment and function.
Gas block installation is a basic AR build task for those with mechanical confidence, but proper alignment and staking are critical. If you're new to builds, a gunsmith can ensure it's set correctly and permanently secured.
The black nitride finish is a durable, corrosion-resistant coating that stands up well to outdoor use and standard maintenance. It provides both protection and a professional appearance.
