Knight is still evaluating a coating process for the new BP's and vent liners that has been proposed, so at this time the breech plug and Vent liner are not treated with any coating.
A Bore Tek application is applied by Knight to the bores of the rifles only.
Ron is correct the flash channel is 5/32" and the Vent Liner specs are .031 +.001 - so it is possible to get one that is .032"
