Is ORF pleasant to deal with ? I bought a used RPK 74 kit from them .I have had it wile I was out of town .sitting at home . I got it around two weeks ago .The bore is bad near the chamber with some missing chrome and pitting . Not exactly an excellent bore . Are these guys pretty decent about these things?It was after all a 600+ kit .I hope they still have a decent replacement ...I have drempt of building this finaly and already invested in a receiver ...Looks like they are only open a couple days a week .
