The Q LLC FIX 8.6 Blackout Pistol represents a versatile and high-performance firearm that stands out for its adaptability and functionality. Initially designed as a candidate for conversion into a short barreled rifle (SBR), it offers all the advantages of the FIX rifle, minus the stock, making it suitable for various long-range applications from hunting to precision rifle shooting (PRS) and tactical use. What sets the FIX apart is its innovative design, resembling aspects of AR platforms while incorporating unique features. For instance, it includes an ambidextrous selector switch and magazine release positioned similarly to an AR rifle, enhancing familiarity and ease of use for shooters accustomed to AR pattern rifles. The AR-style grip further contributes to ergonomic comfort, ensuring a seamless shooting experience. Constructed around a lightweight, monolithic, one-piece aluminum receiver, the FIX prioritizes rigidity and precision. Unlike traditional chassis rifles where the bolt locks into a heavy steel receiver, the FIX's bolt locks directly into the barrel. This design facilitates barrel interchangeability at the user level, allowing for easy caliber changes and barrel length adjustments without requiring gunsmithing. Moreover, the FIX's modular nature extends beyond barrel interchangeability. Components like the stock, bolt or handguard can be swapped out effortlessly, thanks to the use of T-25 screws throughout, simplifying maintenance and customization tasks. Overall, the Q LLC FIX 8.6 Blackout pistol combines advanced design elements with practical usability, making it a standout choice for shooters seeking a versatile, high-performance firearm adaptable to various shooting disciplines and preferences.
