Start with the cartridge you’re building: .223/5.56 for a general-purpose AR-15 , 300 Blackout for short/suppressed builds, 7.62×39 for the AK round, 9mm for pistol-caliber carbines, and .308/6.5 Creedmoor/6mm ARC for large-frame and precision use. Each caliber has its own subcategory.
Barrel length drives velocity and handling, and it must match the gas system length — carbine gas for short barrels up to 16″, mid-length for ~16–18″, rifle-length for 20″ and longer. A correctly matched gas length runs softer and more reliably.
Twist stabilizes bullet weight: faster twists (e.g., 1:7) stabilize heavier, longer bullets; slower twists (e.g., 1:9) suit lighter bullets. Match the twist to the loads you’ll shoot.
Lighter profiles carry easier; heavier/bull profiles resist heat for sustained fire. Most barrels are 4150 chrome-moly-vanadium steel with a nitride finish; 416 stainless options favor accuracy. AR-15 barrels typically have M4 feed ramps.
Muzzle threads must match your muzzle device — usually 1/2×28 for .223/5.56 and 9mm, 5/8×24 for .308 and 300 Blackout. Confirm the thread on the listing.
Match it to barrel length — carbine for ~10–16″, mid-length for ~16–18″, rifle for 20″ and longer.
No. A barrel isn’t a regulated firearm part, so it ships without an FFL.
