Kross Airsoft Design Frac Picatinny Stock Adapter

The Gen-12 MTW is a brilliant HPA shotgun platform — but its stock interface limits what stocks you can run. KAD's Frac Picatinny Stock Adapter solves that by replacing the rear interface with a picatinny rail section, opening up the platform to any pic-mounted stock you want to use.

Made from durable PLA+, the adapter is structurally robust enough to take the recoil cycling of an HPA shotgun without flexing. Folding stocks, skeleton stocks, fixed stocks — anything that mounts to picatinny will work.

Why pic stocks suit shotgun platforms

Shotgun-style airsoft platforms are usually shorter than rifles and run very different cycle dynamics. Pic-mounted stocks tend to be more compact and stiffer than threaded buffer-tube stocks, which suits the Gen-12's particular feel and use case. Folding pic stocks especially make sense — they let you collapse the gun to genuinely pocket-able size for transport between scenarios.
