The Anderson B2K870AP01, also known as the Frontline QR-10.5, is a robust firearm equipped with a 10.5-inch carbine-length barrel chambered in 5.56. One of its prominent features is the unique 9.5 Free-Float Quad-Rail Handguard by Anderson, protecting both the barrel and low-pro carbine gas system. This handguard features Picatinny rails at the 12, 3, 6, and 9 o'clock positions all along its length. Beyond this, it has four QD sling sockets situated at both the 3 and 6 o'clock positions (two on each side, front and rear of rail).
This exceptional rifle also incorporates an H2 weight buffer system, Magpul K2 Grip, and BSL Arm Brace, making it a reliable choice for superior performance. As a part of Anderson's Frontline Series, this product proudly represents a diverse range of American-made firearms designed to adapt to any mission. Built based on data and feedback gathered from rigorous training and accuracy testing, these rifles are derivatives of Anderson's exclusive Defender Series for Law Enforcement.
Each rifle is meticulously fine-tuned with adjusted buffer weights that excellently complement their respective gas systems, ensuring a low recoil impulse. Amply supported by Anderson's TRS handguards and free-float quad rail systems, these rifles can facilitate your transition from one mission to another. The integral Magpul furniture promotes shooter ergonomics, while maintaining a close fit to the firearm, thereby enhancing your tactical engagement.
