LWRC 6.8SPC Advanced DI AR-15 Bolt Carrier Group

The LWRC 6.8 SPC Advanced Direct Impingement Bolt Carrier Group is designed for competition or tactical/duty AR platform builds. It offers a substantial upgrade in terms of both reliability and performance over the MIL-STD parts common in today’s AR market.

This DI bolt carrier group is nickel boron coated, giving it increased resistance to wear and corrosion, as well as reducing friction and helping the action cycle smoother. It utilizes a high precision direct impingement action, resulting in fewer moving parts than a short-stroke gas piston. The carrier, which features a more reliable and sturdy keyless design, is paired with LWRC’s Advanced Combat Bolt, which is constructed out of cutting-edge alloys and built from the ground up around the 6.8mm SPC.

Features:

• 6.8 SPC compatible
• Fits most AR-15 platform upper receivers
• Direct impingement gas system
• Nickel boron finish
• Precision machined components
• High-tech metallurgy
• Keyless design

Despite LWRC being best known for its work on short-stroke gas piston designs, this product performed admirably during testing, reportedly cycling more than 10,000 rounds with no malfunctions. The extractor and several other key parts of the bolt and carrier group have been redesigned, offering greatly improved performance over MIL-STD parts by means of increased precision in part machining and state-of-the-art materials science.
