Compatible with commercial, Mil-spec, or pistol AR15/M16/M4 stocks, braces, and buffer tubes, this adapter offers unparalleled versatility for your HK firearm project.

Crafted from aircraft-grade aluminum and finished with a durable black powder coat, this adapter ensures reliability and longevity. It fits all standard buffer tubes, including commercial, Mil-spec, and pistol variants, providing a perfect complement for HK firearms utilizing a metal backplate such as the HK91, G3, PTR91, PTR-PDW, HK 93, 33, 53, and more.

Each adapter includes a proprietary locking ring for secure attachment to your choice of buffer tube and AR stock, making installation straightforward and hassle-free. Please note that this batch of adapters features a thicker powder coat finish, which may result in a tighter fit or require adjustment to your backplate for optimal compatibility.

Technical Note: This batch of adapters is powder-coated and has a thicker finish than the original anodizing. You may experience a tight fit, or the need to fit it to your back plate.
