Description

The Lantac M-SPEC Bolt Carrier Group is a replacement bolt carrier assembly for AR-15 rifles, intended for budget builds where a milspec-dimensioned component is wanted at a moderate price. It is offered in the 5.56x45mm NATO and .223 Remington chamberings.

The carrier is machined from 8620 steel to milspec dimensions and tolerances and is described by the manufacturer as full auto style with increased mass. It has a nitride finish and a black color, a change from the Type M phosphate finish common on milspec carriers.
