Prominent AR10 Mag Generations (missing one)
From left to right:
OG Waffle magazine in original A pattern
Not Pictured: SR25 Waffle magazines. OG waffle mags refinished and modified to work in the then new SR25’s magazine catch. Magwell was based on the original AR10’s magazine pattern.
M14 magazine with mag catch hole added and plunger on follower for last round hold open. New B pattern for ban era to be able to use plentiful M14 mags grandfathered in before the ban.
M14 magazine revision with indexing piece added for alignment. (This example is missing the plunger for the last round hold open)
Armalite manufactured AR10B magazine. New mags made after the ban for existing AR10B rifles.
AR10A/SR25 Magazine. Current production style AR10 mags, widely standardized by most manufacturers of large frame ARs. This example is made by KAC
Honorary PMag mention.
