SEEKING CAL 500 SLOTTED MAG CENTER CAP SOLUTION

Here are pics of the caps. I believe the old cap is original and was how these were done (modified by Indy mags back-in-the-day) for our 4" SBP mags. I modified the new ones with a Dremel and they fit well. One has to be careful on which deep socket to use. If you need your caps modified, let me know. I'd be happy to do them for you.
