These Center-Feed .458 SOCOM aluminum magazine followers fit 30 round GI magazines, allowing for center feeding of .458 SOCOM cartridges and limiting the magazine to a maximum of 10 rounds. Will not work in new style GI mags equipped with Tan followers, unless the spring is replaced with an old style spring.
Must be REAL GI (general issue) military magazines like Center Industries, Labelle, Adventure Line, OKay, etc.
These will NOT work in COPIES of GI magazines, ie Brownells, D&H, etc.
Note: We have been informed by a customer, that these followers also work in E-Lander magazines with no modifications.
