In reference to 50-round boxes, a friend of mine asked me if they still make those yellow UMC boxes. I know Remington still makes the 250-round yellow UMC boxes but I had to do a bit of research for the 50-round boxes. From the boxes I have I can say that:
- Black Dot UMC
Dull yellow UMC rifle/pistol boxes with an eagle, centered in the front, standing on a black dot with the letters UMC were printed between December 1992 and June 1997. The lot numbers on those boxes equate to the first half of 1993 through the first half of 1998 (W through G).
- Rectangular UMC without cutout
From December 1999 through May 2000 a more vivid yellow box was printed with a prominent UMC inside a rectangle on the front. The lot numbers on those boxes equate to the first and second halves of 2000 (L and M).
- Rectangular UMC with cutout
From April 2001 through March 2004, the same type box was printed but these had a cutout on the left front of the box, as if inviting you to use your left thumb to pull open that tab. The lot numbers on those boxes equate to first half of 2001 through the first half of 2004 (N through W). Those cutouts are still present on green/yellow and green/white Remington boxes.
