From the manufacturer
The .458 SOCOM is a big-bore cartridge designed to function in standard AR-15 upper receivers complete with a standard bolt and magazine. However, in reality, users have found that components designed for use with 5.56 NATO rounds aren't set up for perfect performance with this large-bore cartridge, and so CMMG addressed the issue with its MkW-15 Magazine purpose-built for the .458 SOCOM. Each CMMG MkW-15 Magazine is based on the Lancer L5 Advanced Warfighter Magazine, which was the top choice for shooters of the .458 SOCOM. However, there was room for improvement, so CMMG engineers took the existing magazine design and modified the feed lips to better hold .458 SOCOM rounds with Mfg: Cmmg
