WTB: Colt M16A4 Upper/Barrel Assembly

Hello all,

After speaking with Ken at Specialized Armament I have begun my search for a Colt M16A4 upper/barrel assembly for my “A4” replica build.

Obviously, must have 1/7 twist and be “F” marked. I know this is a long shot but have found this site, forum and members to be first rate so maybe I’ll catch some luck!

Thanks for any help you can provide regarding my search for this item.

Brad
