Lever option
Do not use anti-rotation pins, most of them do more harm than good, they're also mostly incompatible with EMR-A.  A properly designed trigger doesn't need them.   For more info on anti rotation pins, visit this link: https://www.forwardcontrolsdesign.com/anti-walkanti-rotation-pins.html
Due to the lack of standards for 308 ARs, with every manufacture specs differing from another, we do not recommend EMR-A for 308 ARs. 
EMR-A was designed for TDP spec forged lower receivers, if your lower is billet with thick walls, or differ a great deal from TDP specs, please contact us regarding compatibility.

EMR-A is a long in development ambidextrous magazine release for .223 and .308 AR receivers.  Original concept and design was complete in 2015.  After numerous changes to the mag catch geometry and lever shapes,  final design was made into working prototypes in 2017, and first shown in public at Cola Warrior West III.EMR-A is an ergonomic ambidextrous magazine release.  The placement of its lever is well thought out to closely mirror the magazine release button on the right side.  The portion immediately below the bolt catch's lower paddle has a lower profile to avoid interference, heretofore a common drawback of popular ambidextrous mag catches, it is also left smooth.  The serrated length of the lever is split into a shallow V shaped serrations (80%) that conform to the curvature of the user's finger, and straight serrations (20%) that form a natural index point, and provide additional traction.  We refer to the design as Multi-faceted Control Surface, the difference MCS makes has to be felt to be fully appreciated.

Two lever options are available.  Standard and Extended Reach (about 0.09" longer than standard).  Force amplification achieved from a lever means the extended reach lever is easier to reach, it's also easier to press than the standard lever.  For users with small hands or shorter fingers, the extended reach lever makes the EMR-A a joy to use.  For duty and defense ARs, we recommend the standard lever.

A 10.9lb rated magazine catch spring is included with each EMR-A.  We've long considered the standard magazine catch spring to be rather weak (rated at 8.3lb), accidental / unintended mag drops can take place if a user slings his weapon, and has gear and pouches on the vest.  A stiffer mag catch spring mitigates these risks, thus it is an integral part in the EMR-A package.

EMR-A is available as a part of bundled products (please see drop down menus for options).  EMR-A's catch is made from CNC machined 4140 steel and black nitride coated, its lever is 7075 aluminum and Type 3 hard coat anodized.  The roll pin has a shear strength of 800lbs.

Standard for EMR-A, Nov. 2019 and onward

The LP (low profile) mag catch shaft option reduces the mag catch shaft length by a full revolution, or 0.03.  The LP option on the EMR-A (not available for serrated lever EMR-A till mid 2020) reduces the installed height of the right hand mag release button, resulting in a right side mag release button that sits below the mag release fence.  This is our latest step to mitigate accidental / unintended mag drop risks.

The LP on the EMR-A will not reduce the EMR-C's installed height on an AR15/M16 to the point where EMR-C doesn't constitute accidental / unintended mag drop risks.  The LP option's shorter mag catch shaft aims to reduce the installed height of a TDP spec mag release button (such as our EMR), it isn't a solution for extended mag releases, the installed height of which would require a drastically shorter shaft to offset.  EMR-C is meant for 7.62mm ARs, even though it works on an AR15 / M16, we suggest it be relegated to 7.62mm ARs and gaming ARs, not for defense and duty.


* EMR-A's lever pivots on the receiver.
* EMR-A needs to be removed before installing / removing the trigger.  EMR-A is installed and removed in the same manner as a factory mag catch.
* Please wear eye protection while installing EMR, EMR-C, and EMR-A with the 10.9lb mag catch spring, there's considerable spring tension in the 10.9lb spring.
* For 308 ARs, or thicker non-5.56mm spec lower receivers, you will need an EMR-C to offset the AR15/M16 spec mag catch shaft.  EMR-C can be found here https://www.forwardcontrolsdesign.com/EMR-C_p_23.html


* Due to lack of standards for 308 ARs, EMR-A may not work with all 308 AR style lowers.
* Geissele's Maritime Bolt Catch.  Material from either the top edge of EMR-A's lever, or the bottom edge of Maritime Bolt Catch's lower paddle may need to be removed for both to work together.  The close proximity of these two control surfaces makes this combination less than ideal.
* CMC's anti walk pins
* KNS Gen 2 anti-rotation trigger/hammer pins.  KNS Gen2 Mod2 and Gen JJ, and Gen ST (Spikes Tactical) are compatible with EMR-A with standard lever, but not with extended lever. Gen2 Mod2's pins connecting bar may require minor fitting on thicker receivers to create adequate clearance for the EMR-A's lever when pressed.
* HK 7.62mm AR style rifles, MR762 series.
* Aero 308 AR lower receivers.
* Hodge Defense Mod 2  lower receivers.
* APF side folder lowers
* 17 Design billet lowers
* Uintah Precision lowers
* Silencer Co SU 4766 lowers
* Battery assist device levers.
* Receivers with the left side fence around the bolt catch and mag catch, such as some CMT, Magpul and AR15.com billet receivers.  EMR-A requires the left side of the receiver to more or less adhere to TDP spcs.

* May not be compatible with Seekins SP223 and AR10 B receivers.

Worth its weight in GOLD
Works as advertised and fast shipping! I do have the KNS gen II anti roll pins and as it says, you do have to trim the face of the pin holder down. Every once and a while the mag wouldn’t drop because of the conflict of not being pressed down far enough do to the KNS. So I just used dremel to make a notch in it. Now it works perfect!

Outstanding Fit and Finish
Forward Controls Design does not disappoint with fit and finish. So far I have bought a few items from FCD and have been pleasantly surprised and very happy with all of them. From the gas block tool to the EMR-A and EMR-H each one I have bough has been excellent in quality and speed of shipping is simply amazing. Not to mention the small selected gifts that get tossed in as well. This time was a Badger Ordinance sticker and coozy...thanks Roger and crew! All I can say is I am glad you guys don't make rifles as my wallet could not support the habit much longer.

Amazing Product for Left-Handed Shooters
Before buying and using the EMR-A by FCD, I fooled around with a couple of cheaper ambidextrous magazine releases from other manufactures. I found their reliability to be sketchy; I had a common issue where my Magpul Pmags would randomly fall out when shooting, which is absolutely unacceptable. The FCD EMR-A is arguably the BEST upgrade that any left-handed shooter can make to his AR-15. I've purchased approximately four of these and have run hundreds of rounds through on lowers with them installed and have run into absolutely no problems. This upgrade, paired with an handed bolt catch and an ambidextrous charging handle completely levels the playing field for left-handed shooters. These three upgrades allow full control over a standard mil-spec lower receiver for left handed shooters. I personally like the serrated version the best because its much easier to actuate. I hope that Forward Controls Design will one day make one of these for the AR-10. 5/5 stars!

Ambi release
These things are awesome and high quality. Have to train finger placement if your a lefty I kept hitting it at first wish I would have went with the non extended version since it's used as my strong side release. Other than that I love it! Get the stiffer mag release spring lefties.

Awesome upgrade
Combined with the ABC/R the EMR/A they are both an awesome upgrade. Effortless release of the magazine and it doesn’t stick out to much for accidental release of the magazine as well. The spring that comes with the EMR/A also is a great small addition to prevent accidental releasing of the magazine. Very solid product.
