The Sharps BBC is precisely machined from S7 steel which then undergoes our proprietary heat treatment process. Finally the BBC is finished inside and out with NP3®/NP3® PLUS to minimize the need for lubricants, to aid in smooth operation and to make clean up a breeze. The BBC has the SRC logo machine cut on the side of the carrier which is visible when the ejection port door is open. It fits standard AR-15/M16/M4 rifles chambered in .223/5.56mm, 25-45 Sharps and 300 Blackout calibers.

Interested in our products, but hesitant on the design? We offer a 30-Day Money Back Guarantee for certain SRC products including, the Relia-Bolt, Bolt Carrier, and Bolt Carrier Group.
Superior Corrosion Resistance
Every Balanced Bolt Carrier Group is coated with NP3®/NP3® PLUS, an electroless nickel-based finish. This process co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), commonly known as Teflon™, for self-lubricating corrosion resistance. NP3® PLUS offers far more corrosion resistance for marine and other hostile environments. NP3® PLUS gain up to five times as much corrosion resistance over standard NP3® and up to 10X more than regular electroless nickel!
Commonly asked questions:
Question: When developing the
BBC why didn’t you address the designs of the gas key and the firing pin
Answer: We experimented
with attaching a new gas key in a unique way as well as a radically different
firing pin retention system but at the urging of our Professional users we
chose to stay with standard Mil Spec components to simplify battlefield repairs
and to simplify maintenance by the civilian MSR enthusiast.
Question: Does the Sharps BBC
weigh less or more than a standard Mil Spec bolt carrier?
Answer: It weighs the same
as a standard Mil Spec bolt carrier.
Question: Why didn’t you
lighten it and make a low mass bolt carrier?
Answer: Maintaining the
weight is necessary to achieving the balancing effect and because the BBC runs
within the upper receiver and receiver extension in a straighter line it runs
more smoothly resulting in faster sight recovery times while at the same time
ensuring the inertia required to seat a dented or dirty round in the chamber.
Question: Does the BBC work
in the M16?
Answer: Yes, the BBC has
the full-length shroud for tripping auto and burst-fire sears, so the BBC may
be installed in full-auto law enforcement, military and NFA approved rifles.
