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. 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.
