Airtac Remote Feed System (Picatinny/Light Rail Attachment) - Hi-Capa

Airtac Remote Feed System (Picatinny/Light Rail Attachment)Mag type: Hi-Capa

Take control of your loadout’s balance and manoeuvrability with the Airtac Remote Feed System (Hi-Capa Version). Engineered specifically for Hi-Capa users, this kit not only adapts your pistol to be HPA-powered, but it also relocates your M4 magazine placement onto your front Picatinny or under-barrel accessory rail.

Already own an Airtac HPA adapter? The Airtac Modular System version of the Remote Feed System fits directly onto your existing adapter!

By routing BBs through a flexible Bowden spring directly into your modular base, this setup drastically shifts weight away from your grip, giving you faster point-to-target transitions, effortless reloads, and a ultra-sleek CQB profile.

Key Features

• Hi-Capa Magazine Compatibility: Designed to fit easily directly to the base of your hi-capa magazine. Simply install the kit onto your picatinny rail and install the adapter section like a regular HPA adapter.
• Forward Rail Mounting: Clamps securely onto standard 20mm Picatinny/pistol light rails, positioning reload control comfortably in front of your support hand.
• 250mm Bowden Feed Channel: Includes a high-tension 250mm Bowden feed spring that routes BBs smoothly into your replica. The spring can be trimmed to a custom length to perfectly match your rail-to-receiver distance.
• Indestructible Polycarbonate Build: Heavy-duty, injection-moulded polycarbonate magwell and CNC feed components built to withstand direct BB strikes at point-blank skirmish velocities.
• Built-In BB Retention: Features a precision retention catch that drops only 2–3 BBs during high-speed magazine changes.
• Custom Wobble Shims Included: Comes with integrated, swappable rear shims to eliminate side-to-side rattle across various M4 magazine brands.

Modular Setup & Feeding Tips

• Spring Trimming: Always keep a soft, gradual curve when cutting your 250mm Bowden spring. A spring that is cut too short or bent at a sharp angle will create internal drag and cause misfeeds.
• Magazine Selection & Tension: For optimal performance on high-ROF or short-stroked setups, we strongly advise using PTS EPM1/EPM1-S or Amarok magazines. If running ultralight bolts or split-slides, slightly tensioning/pulling the Bowden spring will help push the final few rounds smoothly into the feed chamber.
