Forward Controls Design Ar-15 Abc/R V3 Bolt Catch Rearward Bias Dimpled Black

The Forward Controls Design AR-15 ABC/R V3 Bolt Catch with rearward bias is purpose-built for shooters who run an ambidextrous magazine release on their rifle and need reliable bolt catch access without fumbling. If you've tried using the factory bolt catch alongside an ambi mag release like the Norgon Ambi-Catch, you know the problem: both paddles sit on the same vertical plane, making them nearly impossible to distinguish by feel, especially under gloves or in a hurry. FCD engineered the ABC/R V3 to solve that single, critical issue.

The rearward-biased upper paddle on this V3 model is angled and positioned toward the rear of the receiver, making it naturally accessible for left-handed shooters or right-handers using their extended left index finger to manipulate the bolt catch. The upper paddle features a dual-angle design—5 degrees on the lower 50% and 10 degrees on the upper 50%—that gives your palm or thumb a consistent, ergonomic catch point. Below that sits a subtle notch that serves as tactile feedback as your finger travels down the bolt catch, helping you confirm you're about to hit the lower paddle without looking.

The lower paddle is where FCD's real innovation lives. It extends further than the factory paddle, angles out at 10 degrees, and adopts a "butterfly" profile that increases surface area while maintaining a safe standoff distance from your ambi mag catch lever. This keeps two control surfaces from interfering with each other—a design principle FCD stands behind. The entire assembly is machined from billet 8620 alloy steel, heat-treated, and finished with a DLC coating for durability. Made in the USA, the V3 comes with the bolt catch roll pin, plunger, and spring included.

Frequently Asked Questions

Is the ABC/R V3 compatible with ambidextrous magazine releases?

Yes—that's exactly what it's designed for. The ABC/R V3's extended and angled lower paddle sits on a different vertical plane than typical ambi mag catch levers (like the Norgon Ambi-Catch), preventing confusion and interference between the two controls. The butterfly lower paddle also maintains a deliberate standoff distance from your ambi mag release lever.

What does "rearward biased" mean, and who should use it?

Rearward biased (RB) means the upper paddle is shifted toward the rear of the receiver. This configuration is designed for left-handed shooters or right-handers who use their extended left index finger to operate the bolt catch. If you reload by wrapping your left hand around the magazine well and using your left thumb instead, the forward-biased (FB) version would be better suited to your technique.

Does this come with installation hardware?

Yes. The ABC/R V3 includes the bolt catch roll pin, plunger, and spring, so you have everything needed for installation.

What's the difference between the V3 and earlier ABC/R versions?

The V3 introduced the paddle bias options—forward biased (FB), rearward biased (RB), and standard (centered)—to accommodate different shooting and reloading techniques. Earlier v1 and v2 models used a centered, non-biased upper paddle. The V3 RB version positions the upper paddle toward the rear for left-handed or extended-finger shooters.
