Description:
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 10.3” model features a SOCOM profile with a carbine gas system and .070” 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.
Note: Due to the Crane-Spec gas port size of .070” this barrel was designed to function both unsuppressed and suppressed with 5.56 NATO pressure ammunition. Unsuppressed use with lower pressure .223 Remington ammunition may not yield the best results regarding function.

- 10.3” Government profile chambered in 5.56 NATO
