Need help with picking a upper forge marking for SAMR build.

From what I’ve read, I need a Colt M16a4 CAF upper receiver (Does anyone have an extra one?). What other forging could I use that would be correct for a faithful SAMR replica?

any m4 receiver will work… i’ve used a handful of these, always perfectly fine- http://www.bravocompanyusa.com/Upper-Receiver-assembly-M4-Flat-Top-p/flat%20top%20-upper%20-m4%202.htm

Cool thanks!
I thought only m16a4 uppers were used on the SAMR. So I’m guessing the a4 was replaced with a m4 upper later on.:slight_smile:
Glad an m4 upper is correct! Much easier to find.:smiley:

Found this but I had to come here to ask the experts before looking for parts.
