PROOF Research 284 Rifle Barrel 18" 1:8 Twist

PROOF Research lists this barrel as an 18" 284 with a 1:8 twist. That twist rate is the fast end of the 284 range and it exists for one reason: the long, heavy bullets that need spin to stay pointed downrange.

At 18" this is a short barrel for a cartridge of that diameter, which is the trade people make when they want a rifle that handles well and carries easily. A barrel at this level generally ends up in a build put together around it, not a quick swap on an existing rifle.
