Machined from a precisely cut stainless steel barrel blank and then chambered in many popular calibers, StormLake Barrels are used on many winning competitors personal firearms. All barrels feature full case support and match grade rifling, and are hardened to 40-42 HRC. The cut broach rifling shoots jacketed and lead bullets equally well. Twin ports aid in recoil reduction and help bring the sights down on the target quickly and consistently.
