Aftermarket upgrades don’t always play nicely together, especially when dealing with add on ambidextrous controls. Forward Controls Design EMR-A helps with that! The ground up design includes multi-faceted control surfaces and a shortened, low-profile shaft to help prevent accidental activation of the standard magazine release button.

Note: Due to the lack of standard dimensions for AR-308 platforms, the EMR-A may not work with all 308 ARs.


  • 4140 Chrome Moly steel magazine catch
  • 7075-T3 aluminum lever
  • Multi-faceted Control Surface
  • Heavy duty roll pin with 800lb shear strength
  • Low-profile shaft is 0.03″ shorter than MIL-SPEC
  • 10.9 lb high strength magazine catch spring

The control surfaces of the EMR-A are just as well thought out as the rest of their product line. For example, directly under the bolt catches lower paddle, the EMR-A has a reduced profile and smooth surface to ensure there’s no interference between the two controls. The serrated lever actually features two textured surfaces. The majority of the control surface is cut into a shallow V that centers and guides your finger, with the end of the lever featuring a more steep angle and straight serrations. These natural indexing points make purposeful manipulation of the magazine release fast and intuitive.

FCD has also integrated design features to help reduce the risk of accidental activations. The shaft of the steel magazine catch has been shortened 0.03″, or a full rotation of the magazine catch button. This modification reduces the height of the right hand magazine release button to help mitigate accidental magazine drops. The other feature is the included 10.9 lb spring. Standard MIL-SPEC mag release springs are relatively weak at 8.3 lbs, and this can make dropping your mag unintentionally as easy as slinging your rifle. With the stiffer spring, this risk is significantly reduced!
