Key Features of the RRA A2 Upper:

M4 Feed Ramps: The inclusion of M4 feed ramps ensures smooth and reliable feeding of ammunition, minimizing malfunctions. This is a critical feature for consistent performance.
-
A2 Profile: The A2 profile is characterized by its distinctive forward assist and dust cover, contributing to the classic AR-15 aesthetic. The forward assist aids in chambering rounds, while the dust cover protects the ejection port from debris.
