Forward Controls Design ABC/R
ABC/R (Augmented Bolt Catch/Release) with its angled and larger top paddle and lower paddle with increased surface area, is purpose designed for use with AR15/M16 receivers equipped with ambidextrous magazine releases. Specifically, it is designed to address the difficulty with accessing the factory bolt catch's lower paddle with an ambidextrous magazine catch, such as Norgon's Ambi-Catch, on the receiver. Many of the ambidextrous mag release's lower paddle is on the same vertical plane as the factory bolt catch lower paddle, making identification difficult by feel, especially with a gloved hand.
The ABC/R's chief effort is focused on that single issue. The lower paddle protrudes further, and is angled at 10 degree to give it even more surface area. These measures put the lower paddle and Ambi-Catch's paddle on different vertical planes. That done, we worked on the top paddle. While we don't use it ourselves, preferring to pull back on the charging handle instead to load and reload, we do recognize far more users use it, so the ABC/R's top paddle made slightly larger, and given a 5 degree angle at the lower 50%, and 10 degree angle at the upper 50% cant. The angled paddle makes it easier for the palm or thumb to access.
The notch immediately above the ABC/R’s lower paddle isn’t there by accident. As you run your finger down the bolt catch towards the lower paddle, the notch is meant to provide tactile feedback to indicate the beginning of the lower paddle. It is important be able to differentiate one control surface from another, all without diverting one's gaze to it. The
ABC/R's weight (0.445 oz) has been kept close to that of the factory bolt catch (0.401 oz) to avoid over tasking the spring.
Made from billet 17-7 stainless steel and Melonite coated, the ABC/R is proudly designed and made in the USA.

Thank you GOST for posting the ABC/R :)
I can get a bit wordy in product description, because there's always so much that went into each product. Even so, there's a lot of information I had to omit in order to not make the description into a wall of text.
I go into greater detail in the Design in Focus section, please visit this page for info on design goals and execution :) http://forwardcontrolsdesign.com/Des...cus_ep_45.html

These are a fantastic upgrade over the stock design. Even more of an improvement with a ambi mag release. No more fighting to engage the bolt catch with the improved angle and height on these. Flawless in fit and finish.

Thank you very much Sinner! :D
HVA's AMR paddle is thicker than that of the Norgon Ambi-Catch, we're collaborating on a new design with different paddles that use the same base. With the current HVA AMR, the notch above the ABC/R's bottom paddle can be used to press down to lock the carrier :)

I have them on all my AR's w/ Norgon Ambi Releases. This is a fantastic bolt catch. I was designing my own until Roger released this.

I have a lower with a Norgon that currently has the Seekins Bolt Catch. I might have to do a Pepsi Challenge.

Titan, is that a bump I see on the third serration on the EMR-C? If it is, we should replace it, please email me roger@starsforward.com :)
We have the 308 spec bolt catch graciously donated by Richard Kim, and will be working on a 308 version of the ABC/R :D
