RI2087 vs RI2087-N

portage

Sorry. can't type Chinese in office.

Try to purchase the first AK47, and decide to go with Century Arms N-PAP. But there are two Item#s. RI2087 vs RI2087-N. Does anyone know what differences are between those two item#s. Or they are same, not difference.

Thanks a lot!
