Barrett M107A1 50 BMG 10rd Magazine

This is the 10 round replacement or spare magazine for the Barrett M107A1 in 50 BMG. The body is steel, which is what you want on a box that has to hold and feed rounds this size, and the finish is a matte black.

Inside is a no-tip follower that keeps the long cartridges level as the stack comes up, pushed by a chrome silicon spring. Witness holes let you check the round count without unloading. A second or third magazine keeps an M107A1 working through a long range session instead of stopping to reload one box.
