Let’s have pictures of your NFA Colt’s Only… and the mods you’ve done to them, if any.
I have a 6933 and 6921 on the way. I am trying to decide what I want to do to one or both!! I know I wanna keep the weight down… and I do want rails, so maybe I’ll go with DD Lite or something… plus I like the CTR stocks. Optics is another matrer… Acog or Aimpoint most likely… not sure which yet!
This is an expensive process!
Let’s see em guys!
I have two 6933s. One is largely stock, the other isn’t.
mostly stock

Colt 6450 HT Armory conversion with 7 1/2" upper. The original 10 1/2" upper is un-modified.
Here is a picture of mine. It is currently at my class 3 dealers safe waiting for transfer. 60 days and a wake up I hope.
My Colt 6920 with M-203.
Hmmmmm not many Colts here! Did I make a mistake? Should I have just kept the RRA lower and mixed upper? 
You did fine. It’s just a LOT easier to get factory BM and RRA SBRs than it is to get a Colt.
Here is my Colt 6450 with barrel chopped to 10.5"
