Material Stainless Steel
Manufactured By Lehigh Defense, LLC
The vent liner is produced from 17-4 stainless through hardened to Rc38 - 48 and then gas carbonitited to achieve a surface hardness of Rc60. This high surface hardness reduces wear from flame erosion extending the useful life of the vent liner. Replacement is recommended when the flash hole erodes to 0.038 or if velocity loss is recognized.We advise a drop of oil, or preferred, a quality lithium or molybdenum disulfide grease be used on the vent liner threads upon installing into the breech plug body. The vent liner fits all Lehigh and Savage MLII breech plugs using removable vent liners.
