- 4140 Chrome Moly steel magazine catch
- Extended 7075-T3 aluminum lever

- 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!
Forward Controls Design firmly believes in the elegance of simplicity. Not content to produce purely aesthetic components, they put function before form to create parts and accessories that actually improve the handling and function of your firearms. When you need parts that just work without complication, you need Forward Controls Design.

Works on AR-10
by Ted -
This is the only one I found that work on AR-10. You need the Aero Precision M5 Extended Magazine Catch Button.
by Justin -
Installation is same as any mag catch. It fits all of my lowers well (PSA, Aero, and a local Billet). Mags drop free without issue. You don’t have to buy the matching mag catch button as I have used without issue with standard buttons and the magpul enhanced button, but for best feeling I’d get the matching FCD button. Feels durable and just high quality. Will be buying more when they come into stock agin to add to every lower I have.
Best ambi mag release
Hands down best ambi mag release I have used. I used to run KAC ambi mag releases on all my guns and these are far superior. Pad placement is perfect, activation even with the heavier catch spring is far easier due to the better placement, and it draws your standard side button into the receiver just a tiny bit more to help eliminate inadvertent bumps of the mag release. Now I have to buy more of these to swap out all of them.
