As a competitive shooter, hunter, or gun enthusiast, you rely on the components in your firearm to ensure optimal performance. Gas blocks and gas tubes are essential for channeling excess gas and cycling your ammunition.
They provide crucial improvements in reliability and accuracy while also allowing shooters to customize the adjustability of their rifle’s cycling rate. However, you must ensure that you find the best gear to guarantee high-speed performance from your weapon.
Fortunately, at 3CR Tactical, we offer an expansive selection of tubes and blocks for upgrading your guns. Find the perfect equipment for your armory below, then continue reading to learn more about the role of this vital hardware.
A rail gas block is a component that directs propellant gas from the barrel's muzzle end to operate the firearm's cycling action. A gas tube is a component that connects the gas block to other parts of your firearm's action, such as your bolt carrier group.
The two components work together to direct propellant gas from the barrel and into your firearm's action so that it can cycle properly. Fortunately, these components are often offered together in an AR-15 Gas Block and Tube Combo to simplify the procurement process for you.
No, not all AR gas blocks are alike. While they all have similar functions, there are different types available depending on what type of shooting you do and what kind of performance you need out of your firearm.
For example, standard carbine-length barrels require a low-profile AR-15 gas block, while an extra-long barrel may require a mid-length or rifle-length gas block. This is because the length of the barrel affects how much pressure is needed to cycle the action, and using the wrong size can result in poor performance or even damage to your firearm.
Gas blocks also come in different materials, including steel, aluminum, and polymer. Steel is usually the strongest option but can add extra weight to your gun; aluminum offers a lighter weight but may not be as sturdy; and polymer provides an affordable solution that’s lightweight but not always as durable.
There are several different types of gas blocks available to suit various gun builds and performance needs, such as:
Adjustable Gas Blocks are an ideal solution for firearms enthusiasts who need to customize their gun's performance. This type of gas block enables you to easily adjust the amount of gas pressure that is released, empowering you to tailor the ammunition and rate of fire to your shooting style and preferences.
Front Sight Post Gas Blocks are perfect for shooters looking to upgrade their firearm's front sight post while still maintaining accuracy and shot consistency. These blocks feature a pre-drilled hole that is designed to fit most standard-sized front sight posts.
Low-Profile Gas Blocks are great for shooters who want maximum accuracy from their firearms without needing a full-length rifle barrel. These blocks are designed with shorter overall lengths in order to reduce weight and improve maneuverability when shooting from tight spaces or awkward positions.
