10.5" Rosco Purebred 1-7 twist has about 200 rounds of subsonic ammo fired through it. Please see photo of the gas port showing very little or no wear.
The barrel extension area does have some peening marks left from using a Sharps BCG due to it being a s7 tool steel material they use for their bolts, does not affect function and it still shoots fine, just switching up to short barrel. Please see picture for area mentioned.
