Ballistic Advantage 350 Legend Performance Series 18 SPR Barrel

Sub MOA Accuracy Guarantee – See Tab!

Ballistic Advantage 350 Legend Performance Series 18 SPR barrel is machined from 4150 Chrome Moly Vanadium (CMV) steel with a QPQ (Salt Bath Nitride) Corrosion Resistant Finish. Performance series barrels feature FailZero Nickle Boron coated extra-wide M4 feed ramp extensions. Ballistic Advantage coats their extensions and barrels separately to ensure long-lasting torque values. This Performance Series 18 SPR barrel is configured with a carbine-length gas system and includes a sub MOA accuracy guarantee from BA. What more could you ask for from a barrel with this much value?

Important:  A standard 5.56 1/2×28 flash hider will not have enough clearance for a .350 round to pass. Use a 350 Legend designated muzzle device, or a 9mm 1/2×28 device. Before installing a muzzle device on this barrel, ensure a .350 Legend round will drop freely through the muzzle device bore.
