Rifle Barrels & Barrel Parts for AR-15 and Other Models
GRITR Sports gathered a great collection of the best rifle barrels and barrel parts from all key brands in the gun industry, including Ballistic Advantage, CMMG, Wilson Combat, Daniel Defense, FN, Tactical Solutions, Bravo, and many more.
The types of rifle barrels vary widely, from bull barrels designed for heavy-duty use and heat resistance (most heat-resistant barrels are typically the most accurate) to fluted barrels, known for their lightweight and quick cooling capabilities. The most popular material for rifle barrels is stainless steel often utilized for match-grade barrels due to its high resistance to corrosion and ability to withstand extreme pressures. But you'll also find chrome-moly barrels that boast great durability but are susceptible to rust and corrosion as well as carbon barrels renowned for making less vibration.
We also pride ourselves on a broad range of calibers our barrels are available in. If you're looking for a 5.56 AR-15 barrel, you'll find not only standard 20-inch AR-15 barrels but also carbine-length (10.5"-16") and pistol-length (10" and shorter) designs. Also, we have barrels for Remington, Ruger 10/22, FN SCAR, and other models.
FAQ
How should I choose the barrel size for my rifle?
The size of the barrel for a rifle depends on the specific use of the firearm. For example, hunting rifles typically have barrels ranging from 22 to 26 inches, while tactical or home defense rifles may have shorter barrels for better maneuverability.
Is a 14-inch AR-15 barrel legal?
The legal minimum length for a rifle barrel is 16 inches. Anything less than that would classify the firearm as a Short-Barreled Rifle (SBR), which requires special registration with the ATF and payment of a tax stamp. But if you attach a muzzle device that, together with the barrel, will meet the legal 16" minimum, it's also fine.
What is the average life of an AR-15 barrel?
The average life of an AR-15 barrel can vary greatly depending on factors like the quality of the barrel, the type of ammunition used, and how often it's cleaned. However, a high-quality AR-15 barrel can typically last for around 20,000 to 30,000 rounds with proper maintenance.
