LANTAC 223/5.56 E-BCG Full Auto Style Bolt Carrier Group - QPQ Black Nitride

Product Overview
The LANTAC Enhanced Bolt Carrier Group (E-BCG) is designed for full-auto operation, offering increased mass and lock time. This precision-machined carrier group is coated with QPQ Black Nitride, providing a hard, smooth surface with enhanced corrosion resistance and low friction.

Specifications

• Material: The carrier is made from 8620 steel and the bolt is manufactured from Carpenter 158 or 9310 steel, both shot peened and magnetically particle inspected.
• Coating: The entire carrier assembly is coated with QPQ Black Nitride, a specialized type of Nitrocarburizing Case Hardening.
• Weight: The carrier group weighs 11.7oz, contributing to smoother operation and increased lock time.
• Gas Key: The gas key is hard chrome lined for maximum wear resistance and is fitted with gasket sealer.
• Cam Pin: The cam pin is made from 17-4PH Stainless Steel and is hardened to H900 condition (approximately 45RC).
• Dimensions: All critical dimensions are hard turned and ground after heat treat to ensure precise fit and function.
• Assembly: Grade 8 fasteners are used throughout the assembly, and the gas key is properly staked at four points.

Features

Unique Gas Porting

The LANTAC E-BCG features unique shrouded and forward-facing gas ports that have been resized to vent gas differently from a standard carrier. This design results in a smoother energy pulse with a softer start to carrier movement, making the rifle run flatter and cooler.

Enhanced Lock Position

The flared boss at the tail of the carrier enhances the BCG's lock position within the upper receiver, providing a more consistent and accurate lockup.

Reduced Pressurization

The forward porting and unique shape of the E-BCG assist in reducing pressurization inside the upper receiver, which is particularly beneficial for short-barreled rifles running suppressors.

High-Quality Components

All critical components are precision machined and heat treated to ensure durability and accuracy. The bolt is shot peened and magnetically particle inspected to guarantee reliability.

Compatibility

The LANTAC E-BCG is compatible with all standard AR-15 platforms chambered in .223, .223 Wylde, 5.56, and 300 Blackout.

Additional Benefits

Accuracy Improvement

The consistent lock position and reduced pressurization contribute to improved accuracy.

Improved Functionality

The enhanced gas porting and carrier shape result in smoother operation and a softer start to carrier movement, making the rifle more reliable and user-friendly.

Conclusion
The LANTAC 223/5.56 E-BCG Full Auto Style Bolt Carrier Group - QPQ Black Nitride is a high-performance component designed for precision and reliability. Its unique features and high-quality materials ensure that it will meet the demands of even the most rigorous use cases.
