Transform your Huben GK1 pistol into a stable, highly accurate carbine. This CNC-machined aluminum adapter replaces the OEM back cap with a rear-facing Picatinny rail, allowing you to easily attach folding or rigid stocks without losing any of your GK1’s original functionality.

Key Features

• Versatile Picatinny Interface: Adds a rear-facing 1913 Picatinny rail to attach a wide variety of folding or rigid stocks and braces.
• Dual Functionality: Once installed, you can shoot your GK1 in either pistol or carbine format without needing to remove the adapter.
• Premium Construction: CNC-machined from lightweight 6065 aluminum and anodized black to perfectly match the Huben’s factory finish.
• Unobstructed Access: Sits high on the rear of the action (like a "backpack" above the grip's beavertail), leaving complete access to the grip, loading mechanism, and iron sights (including elevation adjustments).
• Quick 2-Minute Installation: Bolts on simply using the two existing OEM screws. (Requires 2mm and 4mm Allen wrenches, not included).
• Buy with Confidence: Backed by a Lifetime Warranty and our hassle-free return policy.

Important Information & Warnings

• Stock Not Included: This listing is for the Picatinny adapter only. Buttstocks and braces are sold separately.
