Hi Keith and welcome. If it has the original barrel, it was likely manufactured in March of 1982 (fitting the V-prefix range) and has a barrel manufactured in March 1982. Cheers, stay safe and enjoy!

Good evening to you!! Barrel codes can be tricky as they repeat every 20 years, but based on the "V" serial number prefix (1978-1983), AC corresponds to January 1982. Hope this helps. Have a good rest of your day.

Given the serial number prefix "V" (often associated with 1980s Magnum receivers) and the "M" suffix, October 1982 is the most likely date for the receiver.Barrel Code (AC): A = October, C = 1982 or 2010.Receiver (V825769M): V-prefix generally indicates a 12 gauge Magnum receiver from the 1980s, confirmed by the 'M' suffix.

Prob March, 1982. 👍🏻💯‼️

Hi Keith, on the barrel code AC, A is for March. C can be 1956, 1982, or 2008.
Remington never used serial numbers to identify the date of manufacture of it's firearms.
Stay safe & have a great day!
