The Expo Arms Combat Series AR-15 Barrels are designed to give you a premium barrel at an affordable cost. This AR barrel is made from Mil-Spec 11595E certified 4150 steel and features a chrome lined bore to withstand high temperatures for a long barrel life. This 16” model features a government contour with a mid-length gas system and .077” port diameter for reliable function. Additionally, the .750 gas seat diameter is dimpled for securely attaching set screw gas blocks. The 1:7 twist rate is optimal for heavier 62 grain ammunition and the muzzle is threaded 1/2x28 for your favorite 5.56 muzzle device. The entire 5.56 Barrel is Phosphate coated for corrosion resistance and oil absorption. If you are looking for a combat ready barrel that provides exceptional accuracy and reliability, you can’t go wrong with an Expo Arms M4 barrel.

Great barrel

by -

Put about 125 rounds through it the first time out and could have shot all day.

Excellent barrel.

by -

This barrel will shoot. Excellent accuracy with a perfect fit and finish. Gas port is perfect diameter. Mine measured exactly .078" with pin gauges. I feel this barrel was an absolute bargain for the price. Would highly recommend to friends and family. Quality piece.
