AR-15 5.56 NATO 14.5” M4 Barrel 
Designed To Exact Military Specifications

This is a genuine 14.5” M4 barrel designed to exact military specifications. This barrel has been high pressure tested with M197 Cartridge test fired, and was also Magnetic Particle Tested. This barrel includes the Military cage code, and the Military specified packaging, includes the protective VCI tube inserted through every barrel bore, and sealed in a protective VCI bag. These barrels are part of a production run for the us military that were not delivered. This barrel machined from CroMoV Steel, features heavy barrel contour, has a Black Phosphate Finish and includes a Chromium Plated Chamber and Bore (Chrome Lined). It is chambered in 5.56 NATO, has a 1/2x28 thread pitch, Carbine Gas system, fixed front sight post, and has a 1-7 Twist Rate.

Chrome Bore and Chamber:
One of the first modifications that were made to the original M16 in the mid 1960's was the addition of the chrome lined bore and chamber. It is now a world wide standard in the firearms industry for a battle rifle. The chrome bore and chamber is harder than the barrel steel and on the M4 rifles will aid in chambering, extraction, and reliability. It increases velocity, and also resist against fouling and corrosion from extended use in the field. This gives the end user a longer barrel life with less required time in maintenance and cleaning.

HPT / MP Inspected Barrels:
Military specifications require that barrels undergo a HPT (High-Pressure Test) load as a part of quality assurance procedures. Commonly referred to as a proof load, the M197 is rated for 70,000 psi. This barrel is proof loaded and then MPI (Magnetic Particle Inspected) to detect any possible flaws in the barrels surface. This barrel is MP inspected with both circular and longitudinal magnetic fields to assure a high quality finished product.
