LanTac E-BCG 556 Side Charge NIB – AR-15 Enhanced Bolt Carrier Group

The LanTac E-BCG 556 Side Charge is an enhanced bolt carrier group designed for AR-15 pattern rifles chambered in 5.56 NATO/.223 Remington. This BCG features integrated side charging capability, allowing shooters to charge the rifle from the side without using a traditional charging handle—useful for left-handed shooters, suppressed shooting, or when using low-profile optics that interfere with standard charging handle manipulation. The enhanced design maintains compatibility with mil-spec upper receivers while offering improved ergonomics and operational flexibility.

Constructed from 8620 steel with a nickel boron (NiB) coating, this BCG delivers exceptional durability and low-friction performance. The nickel boron finish reduces friction, enhances corrosion resistance, and simplifies cleaning compared to traditional phosphate or chrome-lined carriers. Installation is drop-in for experienced AR builders familiar with BCG replacement; ensure proper headspacing and function testing after installation. The side charging feature requires an upper receiver with side charging port or compatible modification.
