What is a WASP barrel?

W.A.S.P., or Weapon Armored Surface Protection, is simply a modern alternative to chrome lining. W.A.S.P. is a proprietary finish that provides the same durability and ruggedness as chrome lining, without the accuracy loss inherent in chrome lining. Additionally, W.A.S.P. not only protects the inside of the barrel, but the outside as well. Its matte black finish does not reflect. CMMG WA.S.P. corrosion resistance outperforms conventional chrome lining in salt water sea spray tests and provides, rugged reliability and durability essential to military grade firearms.
