Oxpho Blue won't work on a 94 receiver
FWIW, have used Oxpho Blue a fair number of times the last 10 or so years. Most of the time it was for rebarreled rifles built on a mauser action, but there were none mauser action rifles too.
Anyway, learned that a barrel took Oxpho blue pretty good and generally turned out pretty nice. The heat treated/hardened receiver done with Oxpho never looked as good as the barrel.
However, did examine a barreled action once, belonging to a gun store owner. It had been a beat up, shot out barrel bolt action rifle he'd had in a used rifle section for awhile. He'd given it to a gunsmith he used, to be rebarreled. The rifle was going to be his truck rifle, hanging on a rack in its rear window and etc. Told the gunsmith, don't even blue it or anything. When he picked up the barreled action, it'd been blued by the gunsmith. Gunsmith explained to the gun owner, rifle turned out too nice and I just had too blue it for you (using Oxpho)....no charge for it. The gunsmith must have dunked the barreled action in a vat of Oxpho and let it soak for awhile. It was quite a remarkable finish on the rifle.
