Folks, please, give us enough information in your question so we can provide a competent answer. That is all spelled out in the top post in this forum. We need any and all markings on the gun, especially model numbers, to properly identify and evaluate these things.
In this case, we have to go back to the crystal ball. Fortunately, I am fairly sure that the only .222 rifle produced under the Revelation brand was the Stevens 340. There may, however, have been a Revelation Model 222 but I believe that also would have been a Stevens 340 although I do not know what caliber.
Perhaps the poster can supply us with more information so we can be of more assistance....
1) Caliber. Is it .222 Remington?
2) ANY and ALL markings on the gun, ESPECIALLY model number.
The autonomic nervous system provides for involuntary muscle function - the work of breathing, digestion, and so forth. On some folks, that's a pure waste of ingenuity.
