The Augmented Bolt Catch/Release was purpose-designed for the AR15/M16 receiver equipped with ambidextrous magazine releases. With an angled and larger top paddle, and lower paddle sporting increased surface area, it was created to eliminate the difficulty associated with accessing factory bolt catch's lower paddle with ambidextrous magazine catch on that receiver. Identification by feel can be difficult, especially in gloves, caused by most ambidextrous mag releases having lower paddles on the same vertical plane as the factory bolt catch lower paddle. 

In order to remedy this issue, the lower paddle protrudes further and is set at a 10 degree angle for a more even surface area. This puts the lower paddle and Ambi-Catch's paddle on different vertical planes. The ABC/R's top paddle is made larger with a 5 degree angle at the lower 50% and 10 degree angle at upper 50% can't. This makes it easier for the palm or thumb to access. 

The notch immediately above the ABC/R's lower paddle provides tactile feedback to give the user reference for the lower paddle. 

The rearward biased version is for left-handed users that use left index fingers to access the bolt catch paddles. On this version, the upper paddle is shifted to the butt stock end for better accessibility to the upper paddle. 

Machined from billet 8620 alloy steel and treated with black Nitrided finish, the ABC/R is designed and manufactured in the USA.

Please note the ABC/R are not designed for use on 9mm receivers that use Colt 9mm magazines which require a Colt 9mm bolt catch, or Armalite AR10B receivers.

ABC/R v3 is incompatible with CMT based billet lower receivers. The horizontal "butterfly" extension requires the bolt catch bosses to be TDP spec with a radius in the corner.

Excellence in Every Aspect


FCD components are, in my opinion, some of the best components available for your AR-15.
The larger paddle, larger serrations and the slightly ramped overhang at the top provide more surface area and grip for your thumb. The ramp makes it harder for the thumb to slip off the paddle under stress, and the raised lip at the top serves as a repeatable indexing point for both thumb or trigger finger (depending on left or right hand operation).
The tail of the bolt catch is also angled up and flared out, protruding and giving the operator another repeatable index point, and the angle gives easier access and greater leverage, as well as providing more surface area for the operator's finger.
But perhaps the most important feature of this product is the fact that it exactly mirrors the shape of the bolt catch scallop on the VLTOR MUR-1. That's the only reason I bought this.
