| If I buy a factory SBR from Daniel Defense (MK 18), since the lower won't need engraving with SBR markings, can I use other SBR uppers on this? (Example: I remove the 10.5" upper and swap it out with a 14.5" non pinned upper) is that acceptable? Or just the upper that comes with this rifle has to stay on it? Thanks for any help. |
