A fortunate trade for an original Colt early slick-side upper receiver with handguard and 1:12 barrel is now waiting for rebuild into a USAF 604. I'm not certain what to use for the closest option for a lower will be yet. I think a No-NoDak Spud or H&R M16 marked lower would be about the only possibility but I'm, still learning.
I plan on a three-prong flash hider and borrow a chrome BCG from an H&R USAF Slick side upper I've had.
Note the Windage direction arrow normally forged onto the receiver is absent and the drum has only numbers with no arrow. I need to find a Windage Drum with the direction arrow but so far, no joy even for a photo ref.
Photos of proof marks and stamps on the receiver and barrel are interesting and apparently represent earlier styles. The Colt "C" inside a square is barely evident on the fourth photo along with a Triangle "VP" inside that is not readable. Barrel is marked "12" and a "Triangle VP" and "M" appear on right side under the FSB upside down.
This has been fascinating so far and I'm looking forward to putting together what I can to reasonably do justice to the original upper.
Any advice or help along the way will always be appreciated.
