Overview
The Rock River Arms LAR-BT9G R9 9mm AR Rifle delivers a functional and adaptable carbine platform engineered for sport shooting, rigorous training, and general utility. This AR-based system seamlessly integrates familiar ergonomics with the economic benefits of the 9mm pistol caliber, positioning it as a practical choice for consistent operation across diverse applications, including competitive events and personal defense scenarios.
Key Features
Barrel System
The 16-inch fluted stainless steel barrel is precisely engineered to optimize mass reduction while enhancing heat dissipation, a critical attribute for maintaining stability during extended firing sequences. Its stainless steel composition provides inherent corrosion resistance and sustains bore integrity, directly contributing to the rifle’s consistent ballistic performance and overall operational precision. This barrel configuration is integral to the rifle’s effective performance in scenarios demanding consistent shot placement.
Handguard Integration
An integrated 15-inch lightweight M-Lok free-float handguard system prevents any direct contact with the barrel, thereby eliminating potential points of harmonic interference and promoting shot consistency. The M-Lok interface facilitates direct attachment of various firearm accessories, such as lights, grips, or forward controls, without the necessity for additional rail sections or adapters, thereby optimizing modularity and system customization.
Ergonomics & Control
This rifle integrates an adjustable RRA NSP-2 CAR stock, which offers multiple length-of-pull settings to ensure a stable and repeatable shoulder mount adaptable to diverse operator preferences. This is synergistically paired with an ergonomic Hogue pistol grip, a configuration meticulously designed to enhance weapon control and mitigate shooter fatigue, particularly during prolonged practice sessions or dynamic competitive stages.
