Nice job. That is a new gun more than a rebuild.

No poly, just thin coats of truoil.

If it wasn't sealing it was applied much to thin or possibly buffed off between coats. I put around 18 coats on this, buffing every 3-5 coats, letting it dry for anywhere from 24 hours to 3 days before buffing.

Very nice! Makes me want to finish mine.
