Frequently Asked Questions

What makes the Sharps Rifle Co. XPB BCG stronger than standard AR-15 BCGs?

The XPB BCG is constructed from S7 tool steel, which provides a 75% increase in tensile strength over standard Carpenter 158 steel. It also features a durable Diamond-Like Carbon (DLC) coating for enhanced lubricity and wear resistance.

How does the XPB BCG improve AR-15 reliability and shooting experience?

The XPB BCG incorporates design features like relief cuts to reduce mass and minimize carrier cant during cycling. This results in less felt recoil, smoother operation, and reduced wear on the rifle's components.

What quality control measures are used for the Sharps Rifle Co. XPB BCG?

SRC employs rigorous batch testing, including High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI), to ensure each BCG meets high standards for safety and reliability before it reaches the consumer.

Is the XPB BCG easy to clean?

Yes, the Diamond-Like Carbon (DLC) coating on the XPB BCG offers excellent lubricity and makes cleaning exceptionally easy. Carbon fouling can often be wiped away with a dry cloth, even after extensive use without lubrication.
