10/60 Magpul D-60 AR-15 5.56 Drum PMAG

10/60 side riveted Magpul D60 5.56 black AR15 drum P-Mag. A 1/8"  rivet has been inserted into the side of the drum to block the follower and limit the capacity of the drum to 10 rounds. It may hold 10 rounds tight, we're going to err on the side of caution with it. The rivet is covered up by one of the retaining clips, so it may be wise to carry a flathead screwdriver if you take the drum out in public to display the rivet.
