Built by Sons of Liberty Gun Works, renowned for their “No Compromise” philosophy, this rifle is meticulously crafted to deliver exceptional ballistic performance and unwavering reliability in the most demanding environments. Optimized for the potent 6MM MAX cartridge, the BS M89 platform integrates superior components and precision machining to ensure every shot finds its mark, making it an indispensable asset for discerning shooters who demand peak performance.
Key Features
Superior Ballistics: 6MM MAX Cartridge
Chambered in the high-performance 6MM MAX, this rifle is designed to maximize the potential of the cartridge. The 20-inch barrel length is critically chosen to achieve optimal velocity and energy transfer, significantly extending effective range and enhancing terminal ballistics. This configuration mitigates bullet drop and wind drift more effectively than standard calibers, providing a flat trajectory and superior accuracy at extended distances.
Precision Machining and Duty-Grade Components
The SOLGW BS M89 is a testament to KFF Defense’s commitment to quality. It features a precision-machined 7075-T6 aluminum receiver set, ensuring a tight, consistent fit that contributes directly to accuracy. The heart of its precision lies in the 20-inch barrel, typically crafted from 4150 CrMoV steel, precisely rifled and often QPQ nitride finished for exceptional durability, corrosion resistance, and consistent shot-to-shot performance. The signature SOLGW M89 Drivelock handguard provides an incredibly rigid, free-floated platform, isolating barrel harmonics and further enhancing accuracy while offering extensive M-LOK mounting solutions for accessories. Every component, from the robust bolt carrier group with its Carpenter 158 steel bolt to the mil-spec controls, is selected and integrated to withstand rigorous use.
Unwavering Reliability and Performance
Sons of Liberty Gun Works rifles are built for duty, and the BS M89 is no exception. Each rifle undergoes stringent quality control processes to ensure flawless operation. The rifle-length gas system, combined with a high-quality gas block and stainless steel gas tube, is perfectly tuned for the 20-inch barrel, promoting smooth cycling, reduced recoil, and enhanced longevity of internal components. This system is optimized to function reliably with a wide range of 6MM MAX ammunition, delivering consistent performance when it matters most.
Ergonomics and Modularity
Beyond its internal precision, the BS M89 offers superior user ergonomics. The M89 Drivelock handguard provides a secure and comfortable grip, while its M-LOK interface allows for versatile attachment of lights, lasers, and grips. Standardized AR-15 controls are intuitive and familiar, allowing for rapid manipulation. The rifle is typically outfitted with a high-quality adjustable stock and ergonomic pistol grip, providing a customizable and stable shooting platform to fit individual operator preferences.
