Forward Controls Design LMC Low Profile AR-15 Magazine Catch

In 2018, Forward Controls developed the LP (low profile) shaft option for EMR-A, which has become standard on all EMR-A in late 2019. They also lengthened the EMR-A plate's "ramp" section (the part that engages the magazine's mag catch cutout/indentation). The LP shaft is designed to lower the installed height of the magazine release button (on the right side) so its top can sit slightly below the fence, while the longer ramp on the plate is designed to lengthen the magazine catch's travel before a magazine is dropped. Both features are meant to mitigate accidental/unintentional magazine drops. The "ramp" of the plate length is only 0.05", a magazine catch only needs to travel over 0.05" before a magazine is dropped. TDP spec M16 lower receivers, and semi auto AR15 forged receivers based on TDP dimensions have a magazine release fence to prevent accidental/unintentional magazine drops. With a TDP spec magazine shaft and magazine release button, the top of the button is usually flush wi
