Sootch reviews the Sharps Rifle Company Balanced Bolt Carrier, including range demo.
The Sharps BBC is precisely machined from S7 steel which then undergoes their proprietary heat treatment process. Finally the BBC is finished inside and out with NP3 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.
