Product Info for LANTAC M-SPEC 5.56x45mm NATO/.223 Remington Bolt Carrier Group

Not every customer has the requirement or budget for a fully enhanced, top of the line AR15 accessory. Many users simply need a quality milspec component supplied at a sensible price.image

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 NiB 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 dimension are exact to mil specifications. It is then NiB (Nickel Boron) coated rather than Type M Phosphated to give increased corrosion resistance, durability, lubricity 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 are 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 are ideal for budget builds where quality and reliability are still paramount.
