With the shorter carbine gas system and the increased gas port pressure, the carbine cycled faster, and at times the cycle rate could be faster than the magazine would feed ammunition. One of the modifications done to increase reliable feeding included enhancing the angle and the length of the feed ramps. This USGI modification was done to both the barrel extension and the upper receiver, creating a longer and steeper feed ramp. These Mil-Spec M4 feed ramps are part of the original CNC manufacturing process. As a result, the factory machined M4 feed ramps on the receiver are hard coat anodized which adds significant strength to the aluminum. This feature is offered on all BCM barrels.\n\u003cbr\u003e\u003cbr\u003eStripped 11.5\"\" carbine gas Standard 11595E barrels with pre-installed and dimpled gas ports for secure gas block installation.      M4 Feed Ramp: Enhanced feed ramps for reliable feeding, part of the original CNC manufacturing, with hard coat anodized finish for added strength.      USGI 1\/7 Twist Rate: Preferred for its versatility and effectiveness with heavier 5.56 ammunition.
