Lantac E-BCG Enhanced 308/762 Bolt Carrier Group NiB Finish

The Lantac E-BCG Enhanced 308/762 Bolt Carrier Group NiB Finish is engineered for demanding environments where weather resistance and durability are essential. Its advanced NiB Electroless Nickel Boron coating, applied via the UCT EXO process, provides a robust barrier against moisture and corrosion, making it suitable for use in adverse conditions.

This bolt carrier group is designed for AR10 platforms and features a DPMS pattern, ensuring compatibility with a wide range of rifles. The forward porting and enlarged vents help manage gas flow, reducing internal pressurization and supporting cleaner operation, especially when using suppressors.
