Adjustable Blade Arm Brace (AR15 Pistol)

thingiverse

Adjustable arm brace specifically designed for the AR15 platform enhances handling and stability on AR15 pistols by mounting directly to a Commercial-spec carbine extension tube. It extends and collapses to match available positions on your tube without requiring modifications. A latch is included; users must source their own spring, plunger, roll pin, and nut. Two design options are provided: 'Open' with a hole running through the full length of the brace, and 'Filled' with the hole sealed at the rear end. The 'Test' file should be printed first to confirm fit on your extension tube. One-piece and two-piece CAD files are included for printing flexibility, accommodating beds with limited Z-range. Full CAD files are available for users to customize according to their needs and style. Important: This product is designed exclusively for pistol or airsoft use only. It is not intended as a stock and should never be used to shoulder fire. Redesigning it as a stock is strictly prohibited. Users must adhere to BATFE and NFA regulations at all times, referencing included ATF guidance for responsible and lawful use.
