rdb parts

For those of you who have a rhino rail from life industries, how long did it take to get in? I ordered one on 11/16 and it’s now 12/10 and have yet to get it. Thoughts?

Kel tecs website has a parts link but nothing beyond pins and mag releases. I want a 20in barrel and maybe some other spare stuff in case my gun breaks during the impending social collapse. Can anyone send links?
