Description

The Lantac M-SPEC 5.56/.223 Bolt Carrier Group is a precision-crafted, high-performance accessory designed for AR15 and M16 rifles. It is manufactured in the USA and offers a combination of military specification dimensions, tolerances, and materials with added enhancements to elevate its performance beyond milspec standards, all at an economical price point.

Features

Enhanced Performance

The M-SPEC line features a full-auto style carrier with increased mass to enhance lock time and smooth operation. The entire carrier assembly is QPQ Nitride coated for increased corrosion resistance and durability. This specialized coating creates a very hard, smooth surface with a low coefficient of friction, contributing to the BCG's overall performance and reliability.

High-Quality Materials

The carrier is precision machined from 8620 steel, case hardened, and hard turned/ground to exact milspec dimensions. The bolt is manufactured from Carpenter 158 or 9310 steel, shot peened, and hard turned/ground to meet military specifications. The Lantac CP-R360 domed head cam pin, precision-machined from 17-4PH stainless steel and hardened to H900 condition, further reduces friction and wear within the upper receiver.

Advanced Coating

The QPQ Nitride coating is a specialized type of nitrocarburizing case hardening that creates a very hard, smooth surface. This coating provides increased corrosion resistance and a low coefficient of friction, ensuring the BCG runs smoothly and reliably.

Unique Design

The E-BCG features unique shrouded and forward-facing gas ports that have been resized to vent gas differently compared to standard carriers. This design results in a system that runs flatter with a smoother energy pulse, a softer start to carrier movement, and less pressurization of the upper receiver when running a suppressed barrel.
