Since the Huben GK1 was released, customers have asked for a way to add a buttstock to their pistols. The wait is over. Introducing the Saber Tactical Huben GK1 Stock/Brace Adapter! Key Features: Versatile Attachment: Bolt on a rear-facing Picatinny rail and attach any number of folding or rigid stocks to your GK1, increasing stability and accuracy for longer shots. Quick Installation: The SBA connects to your GK1 with two elongated stainless steel screws (included), replacing the stock screws. Installation requires only 2mm and 4mm Allen wrenches (not included) and takes just a few minutes. Dual Functionality: Once installed, you can use the airgun in pistol or carbine format without removing the adapter and without losing any of the GK1's functionality. High-Quality Construction: Machined from 6065 aluminum and anodized black to match the Huben. It sits like a Picatinny backpack on the rear of the action, above the grip's beavertail, leaving full access to the grip, loading mechanism, and iron sights, including elevation adjustment. Important Information: Buttstock Sold Separately: Choose from a variety of folding or rigid stocks to customize your setup. Free Installation: Available when ordered with a new Huben GK1.
