The American Precision Arms Gen 4 Little Bastard Self Timing Stainless muzzle brake delivers precision control through the newly calibrated URP tunable top ports, engineered for maximum adjustment and the flattest shooting performance available, hands down. Built in stainless with a 5/8"-24 thread pattern, this brake measures 2.70 inches in overall length and has a 1 inch diameter, pairing compact, near-zero recoil with dependable gas management for a consistent point of impact. The Gen 4 design emphasizes optimized port size and location to fine-tune how gas is fed into the top ports, enabling zero vertical movement and enhanced flattening of the shot cycle. Ideal for high-precision builds where repeatable trajectories and reduced muzzle rise matter, it integrates seamlessly into rifles requiring reliable self-timing operation and durable stainless construction. This model embodies American Precision Arms commitment to engineering that prioritizes shooter confidence, offering a robust component that supports repeatable performance across a variety of calibers and rifles while maintaining a clean, professional look and feel for serious field and range use.
