Lantac Mil-Spec 5.56 Bolt Carrier Group – TIN

Lantac Mil-Spec 5.56 Bolt Carrier Group – TIN

M-SPEC® is a range of AR15 accessories and components that follow the military specification in dimensions, tolerances, and materials with the addition of a few upgrades and enhancements to raise the performance standard of the product above the ‘milspec’ rating, while retaining the same economical price point as traditionally offered by other providers.

Offered in 5.56/.223 Caliber the Lantac M-SPEC® TiN 5.56/.223 BCG is precision machined to milspec dimensions and tolerances. The carrier is full auto style with increased mass and is manufactured from 8620 steel, case hardened, and hard turned/ground so that internal dimensions are exact to mil specifications. It is then QPQ Nitrided rather than Type M Phosphated to give increased corrosion resistance, durability, and performance.

The Bolt is machined from Carpenter 158 or 9310, shot peened, and hard turned as per the military spec.

Each BCG is further fitted with a Lantac CP-R360 domed head cam pin, which is precision machined from 17-4PH stainless steel, hand polished, and hardened to H900 condition. This further reduces friction and wear within the upper receiver.

The M-SPEC® line of products is ideal for budget builds where quality and reliability are still paramount.
