DD MK18 upper w/ options

I’ve got a factory assembled Daniel Defense MK18 RISII FSB upper with a 10.3" barrel and A2 flash hider. NO BCG/CH.
This is Daniel Defense- best of the best in my opinion

I have hit it with a pretty cool looking coat of Digital Camo, I like it personally- if you do, I’ll tell you how to match your lower- if not- brake cleaner!

Upper with rail NO BCG/CH: $575 (trades preferred- look below. I am reserving the right to decline cash offers, just because im offering a fair price doesn’t mean I can replace it for a fair price)
DD MK18 RIS II FSB rail: ($399 online) $275
Vikings Tactical LUSA: ($49.99 + shipping online): $30
Arms 40-L rear BUIS. spring loaded. (i believe, correct me if I’m wrong, kryloned brown, hence the discount): $50

I’m torn between selling the upper OR just trading out the rail and gas block.
I will trade for a built upper with the following specs- or REALLY close to the following specs:
10.3/10.5" barrel (quality)
Troy vtac rail- 9"
Troy Buis (FDE preferred)
QD socket would be nice, as well as rail pieces.

I will also trade the rail for a troy vtac alpha rail with buis.
