National Match competition is a prestigious discipline in American marksmanship, tracing its roots back to 1903. The AR15 part of the competition is known as the Service Rifle Competition. Held annually at Camp Perry, Ohio, and governed by the Civilian Marksmanship Program (CMP), these events test shooters' skills at various distances, emphasizing accuracy and precision. There are strict limits on the configuration of the rifle and the optic, if used, the idea being that the competition is a test of the shooter, not the equipment. But, every competitor wants the best equipment allowed. The competition has a rich heritage, fostering both civilian marksmanship and military preparedness, and continues to be a proving ground for top-tier shooters and equipment manufacturers like Rock River Arms.
The heart of this upper receiver is RRA's match-grade stainless steel barrel. Its .223 Wylde chambering and the 1:8 twist rate is optimized for stabilizing a wide range of match-grade bullets, particularly in the 55 to 62-grain range. This versatility allows competitors to fine-tune their ammunition choice for varying wind conditions and distances encountered in National Match events.
RRA's 1/2x28 0.04 aperture NM rear sight is a marvel of precision engineering. The 0.04" aperture provides an optimal balance between sight picture and target acquisition, crucial for the rapid target transitions in NM competitions. Fully adjustable for windage and elevation, this sight allows for minute adjustments to compensate for environmental factors.
The A2 upper receiver itself is precision-machined to exacting tolerances, ensuring perfect alignment with the barrel and sight system. This level of accuracy is essential for the sub-MOA groups demanded in high-level competition.
