Ok, I knew that standard barrel nuts had to be opened up, but was not aware of the Seekins. Is the Seekins barrel nut steel?
The standard barrel nut will need to be opened and reparked, as well as the Seekins if it is steel. If it's aluminum it could either be left in the white, Cerakoted, or we could send it to be anodized with our next batch of parts. Park will be a couple of weeks, we'll send it out in the next batch, anodizing will probably be 4-6 weeks depending on when the next batch is ready to ship out. Cerakoting would be a few days for black.
Let me know which way you'd like to go and the material and I can give you a quote.
