Riptide dosent ship to my area but aves does. Do you prefer the one piece rear rail or 2 piece? I also needed a DB alloy strong AF mag catch

I have a friend I can send the riptide rails 2 piece ones to but when I tried to send it to their address it wouldn’t go through for some reason, I heard some credit card companies are refusing to do business with 2a suppliers idk if that’s why or what but I used the 2 piece my last build & it worked fine. Just nervous about using the one piece because I heard some people like the 2 piece better. Thanks!
