I have 2 brand new never used Colt 20rnd mags marked as followed:
Horsey logo, COLT AR-15
They have alloy followers and IU on the mag body, does anyone know when they were made and what they are worth, any help would be appreciated, thanks John
The UI on the magazine body stands for Universal Industries, the maker of the magazine.
You can get anywhere from $20 to $35, maybe more, depending on how bad someone wants Colt floor plates.
