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

The Forward Controls Design AR-15 ABC/R V3 is a purpose-built bolt catch upgrade that solves a real problem on modern AR-15s: when you run an ambidextrous magazine release, the factory bolt catch becomes awkward to find and operate by feel, especially with a gloved hand. This rearward-biased version shifts the upper paddle toward the rear of the receiver, making it naturally accessible for left-hand shooters who extend their support-hand index finger to release the bolt. It's the kind of refinement that separates a rifle that feels right from one that fights you.

FCD engineered the ABC/R with two distinct paddle surfaces—each optimized separately. The upper paddle is angled and enlarged to give your thumb or palm a bigger, more intuitive target; the rearward bias on this V3 puts that paddle exactly where left-hand users need it. Below that sits the distinctive "butterfly" lower paddle, which extends horizontally to increase contact area without fouling the nearby ambidextrous mag catch lever. A tactile notch sits immediately above it, giving your finger a distinct "step" to feel as you move down the bolt catch—letting you identify the lower paddle instantly without looking. The 10-degree angle on the lower paddle tilts it away from the mag catch's control surface, putting both on different planes so they're never confused.

Built from billet 8620 alloy steel with a hard DLC coating and proudly made in the USA, the ABC/R V3 is designed for shooters who demand precision in ergonomics. The rearward-biased upper paddle makes this version the go-to choice for left-handed shooters or anyone using an extended support-hand index finger to run the bolt catch. Installation hardware—roll pin, plunger, and spring—are included.

Frequently Asked Questions

Who should choose the rearward-biased ABC/R V3?

The rearward-biased (RB) version is designed for left-hand shooters and anyone who uses their extended left index finger to operate the bolt catch. The upper paddle is shifted toward the rear of the receiver to make it more accessible from that position. If you're right-handed and use your left thumb on the magazine well to release the bolt, consider the forward-biased (FB) version instead.

Does this bolt catch work with ambidextrous magazine releases?

Yes—that's what the ABC/R was designed to do. The butterfly lower paddle is shaped to clear the lever of ambidextrous mag catches like the Norgon Ambi-Catch, and the angled design places both control surfaces on different vertical planes so they're easy to distinguish by touch.

What's included in the box?

The ABC/R V3 comes with the bolt catch, plus the roll pin, plunger, and spring needed for installation.

Will this fit my AR-15?

The ABC/R V3 is designed for AR-15 and M16 receivers with standard bolt catch mounting. It's a direct replacement for the factory bolt catch.
