This barrel is made from 4150 chrome moly steel with a chrome lined bore and chamber which is ideal for extremely large round counts and barrel life. It has also been coated with a manganese phosphate finish to provide excellent corrosion and wear resistance. Spikes Tactical barrels are built to last and will make your next M4 rifle build ready for any field conditions.


  • Magnetic particle inspected and stress relieved
  • 5 56 Chrome lined bore and chamber for high round counts and longevity
  • Manganese Phosphate coating for corrosion and wear resistance
  • Chambered for 5.56x45mm ammunition
  • Government profile for light weight durability
  • M4 feed ramps in barrel extension for reliable feeding
  • Mid-length gas system balanced for reliability and recoil reduction
  • Threaded 1/2x28 for muzzle devices like flash hiders, muzzle brakes, suppressors, and compensators
  • 1:7 twist rate for bullet stabilization of heavier bullets

This 5.56 NATO barrel also features a government profile that is designed to reduce weight while still retaining rigidity and has a mid-length gas system that combines reliability with recoil reduction. It has a .750 gas seat diameter for the attachment of a variety of gas blocks from standard to adjustable. The 1:7 twist rate is designed to be used with heavier bullets like 62 grain and higher. However, it can still shoot lighter bullets, it just won’t be as consistently accurate. There is a large amount of 62 gr XM855 military surplus ammunition on the market for extremely low prices so you will be able to shoot with this barrel all day. And because the barrel extension has M4 cut feed ramps you don’t have to worry about reliability issues no matter what ammo you use whether steel cased or brass.
