The Bushmaster QRC BFSIII is a semi-automatic rifle chambered in 5.56 NATO / .223 Remington with a 16-inch M4-profile barrel, 7075-T6 aluminum receivers, and a matte black finish. Its defining feature is the BFSIII binary trigger, which fires on both pull and release, allowing for a significantly higher round rate than a standard semi-automatic trigger.

Features 

 
The BFSIII trigger is a three-position system: safe, semi, and binary. In binary mode, a round fires on both trigger pull and trigger release. This is a legal semi-automatic configuration and produces a noticeably higher rate of fire than conventional triggers without fully automatic mechanics. 
 
At 5.18 lbs., this is on the lighter end for an AR-pattern rifle, which helps with extended carry and fast target transitions. The six-position collapsible stock adjusts overall length from 32.5 to 36 inches. The C.A.R. handguard has rail sections for mounting optics and accessories. 
 
The M4 barrel profile keeps weight down without the barrel contour being so thin it heats excessively under rapid fire. 
 

Usage 

 
The binary trigger makes this rifle particularly well-suited for the range and competition scenarios where rapid fire is part of the exercise. Buyers typically know the BFSIII before they buy. The trigger is the reason most people choose this specific configuration.

The Bushmaster QRC Gen III generates conversations dominated by the binary trigger, which is not surprising given that it's the primary reason buyers choose this particular configuration.

Performance at the range is consistently rated well. People report reliable cycling across different ammunition types and good accuracy. The binary trigger takes practice to run smoothly, most owners go through a learning curve before they're comfortable firing on both pull and release intentionally, but those who put in the range time tend to be satisfied.

Build quality gets positive feedback; the 7075-T6 aluminum receivers and overall construction feel solid. The rifle is notably light at 5.18 lbs., which makes extended sessions and fast movement easier.

Customization gets discussed regularly. The platform accepts standard AR accessories, and owners add optics and other parts freely. Some find the stock and handguard adequate as shipped; others swap them out as personal preference dictates.

Pricing splits opinions. Some feel the binary trigger addition justifies the cost relative to a standard QRC, while others compare it against buying a base rifle and adding an aftermarket binary trigger separately. Customer service experiences with Bushmaster are mixed in the broader owner community, which comes up in some discussions.

Overall, the rifle earns its following from shooters who want binary trigger functionality built in from the factory rather than added later.
