What the torque spec?

Manufacturer Answer
A
Answered by Faxon Firearms, Manufacturer from OH, United States, on February 19, 2025

LR-308 barrels should be mounted with between 35 and 80 ft/lbs. Check with the manufacturer of your barrel nut/handguard as they may have a specific torque requirement.

Q
Tq, member, from TN, United States, asked on February 10, 2025

Is this barrel capable of handling off the shelf 7.62 ammo?

Manufacturer Answer
A
Answered by Faxon Firearms, Manufacturer from OH, United States, on February 19, 2025

This barrel has a .308 Winchester chamber so can function with some 7.62x51NATO ammunition, but it has a tighter headspace tolerance window than 7.62x51NATO ammunition so some rounds may not chamber. We recommend using only .308 Winchester marked ammunition for best performance.
