This kit features an 18-inch barrel constructed from durable 4150 CrMoV steel with an HBAR profile and a 1:16 twist rate, optimizing it for improved accuracy with .350 Legend ammunition. The carbine-length gas system ensures reliable cycling, while the micro low-profile gas block maintains a streamlined setup.
