There are a lot of different ways to customize AR platform firearms. While some modifications are ergonomic or even just cosmetic, others change how the weapon itself functions. The ultimate goal of any modification is to create a better shooting experience. Accuracy and control are easy to improve with the right additions to your AR. Muzzle devices, captive buffers, and lightweight components can help to create a weapon system that affords the operator greater control, but if you really want to manage motion on firing, there’s another component that becomes integral to ensure your AR cycles reliably. A quality AR gas block such as Aero Precision’s Low Profile Gas Block is a great way to improve reliability in your gas system.

Gas Management

AR platforms use the gas pressure produced on firing to cycle the bolt carrier group. While a certain amount of pressure is required, most weapon systems create much more pressure than is required for the system to effectively operate. However, a low-quality AR gas block might cause gas leak, therefore, your weapon will not cycle correctly. A high-quality gas block is essential if you want to a weapon that won’t fail on you when you needed it the most.

Low Profile Flexibility

The Aero Precision Low Profile Gas Block comes machined to fit barrels with an outer diameter of either .625, .750 or .875 inches. The low profile stance of the Aero low pro gas block allows it to fit under most free-floating handguards without concerns about clearance. That means you can use it as part of your build without worrying about which forend it will work with.

Quality American Manufacturing

Aero Precision manufactures their low pro gas block in their state of the art facility in Tacoma, Washington. American sourced 4150 hardened steel is precision machined to exact specifications and given a corrosion-free phosphate or nitride coating that will protect your investment wherever you operate.
