KAK Shockwave Blade Key Features

  1. Pistol Stabilization: The primary function of the Shockwave Blade is to stabilize AR pistols, improving accuracy and control. It effectively serves as a brace that helps shooters maintain a firm and steady grip on their firearm, especially when shooting with one hand.
  2. Adjustability: One of the standout features of the Shockwave Blade is its adjustable length. The Blade can be extended or retracted to accommodate different arm lengths and preferences, providing a customizable fit for a wide range of shooters.

  4. Compatibility: The Blade is designed to fit on most AR pistol platforms, making it a versatile choice for those with various pistol builds. Its compatibility with standard buffer tubes (1.11-1.25 inches in diameter) further extends its usability.
  5. ATF Approval: The Shockwave Blade is ATF approved as an arm brace, which means it can be legally attached to an AR pistol without turning it into an NFA-regulated firearm. This approval offers peace of mind to users concerned about legal compliance.

Installation Process

Installing the KAK Industries Shockwave Blade is a straightforward process that can be completed with basic tools and minimal expertise. Here are the general steps to follow:

  1. Gather Tools: You’ll need a wrench (usually a castle nut wrench), an Allen wrench, and a screwdriver for the installation.
  2. Prepare the Pistol: Ensure your AR pistol is unloaded and the safety is engaged. Remove the existing buffer tube and end plate if necessary.
  3. Attach Buffer Tube: Slide the buffer tube into the receiver and secure it with the castle nut. Tighten the castle nut using the wrench until it’s snug, ensuring that the buffer tube is aligned properly.
  4. Install the Blade: The Blade attaches to the buffer tube using the provided set screw. Loosen the set screw with the Allen wrench and slide the Blade onto the buffer tube until you achieve the desired length. Tighten the set screw to secure the Blade in place.
  5. Adjust Length: Extend or retract the Shockwave Blade to fit your arm comfortably. Ensure it’s securely locked in position.
  6. Final Checks: Verify that all components are properly tightened and aligned. Perform a function check to ensure the pistol operates safely.

Build Quality

The build quality of the KAK Industries Shockwave Blade is generally commendable. The use of high-quality polymer in its construction ensures durability without adding unnecessary weight to the firearm. The polymer is robust enough to withstand the recoil forces generated by AR pistols while remaining resistant to wear and tear.

The set screw that secures the Blade to the buffer tube is well-designed and reliable. It provides a secure connection that minimizes wobble and maintains stability during firing. However, it’s essential to ensure that the set screw is adequately tightened to prevent any play in the Blade’s position.

The castle nut wrench provided for attaching the buffer tube is also of good quality and helps facilitate a secure fit. Overall, the Shockwave Blade’s build quality inspires confidence and is well-suited for its intended purpose.

  3. Minimalist Design: The Blade’s minimalist design complements the aesthetics of AR pistols and ensures a sleek, unobtrusive appearance. It doesn’t add unnecessary bulk or protrusions that could hinder maneuverability.
  4. Steady Grip: The textured surface of the Blade provides a firm and secure grip, even in adverse conditions. This is crucial for maintaining control, especially during rapid fire or one-handed shooting.
  5. Lightweight: The polymer construction of the Shockwave Blade keeps weight to a minimum, ensuring that it doesn’t significantly affect the overall balance or handling of your AR pistol.
