Barrels for AR-pattern rifles across lengths, profiles, and chamberings. Length trades velocity against handling, profile trades weight against sustained fire, and the gas port length has to match the system you are building around it.

Twist rate decides which bullet weights stabilise. If you are weighing a chambering, our comparison of 6mm ARC against other AR-15 calibers covers the trade-offs. Barrels are not firearms and ship direct.
