Designed specifically to complement the unique geometry of the Vorsk VMP-2 platform, the Airtac Vorsk VMP2 Modular HPA Adapter converts your gas SMG to run on regulated High-Pressure Air (HPA) using high-capacity M4 or MP5 AEG magazines. Featuring a shortened, flush-fitting design, this modular adapter maintains a clean, balanced profile while giving you hyper-consistent FPS, rapid feeding, and zero gas cool-down on long bursts.
This Plug and Play unit comes completely pre-assembled straight out of the box fitted with Airtac’s custom injection-moulded gas router, high-flow internal valve, and precision feed lips. No donor gas magazines, tricky disassembly, or harvesting factory parts required!
Shortened, flush-mount architecture engineered specifically to sit clean against the VMP-2 receiver for optimal aesthetic flow and handling.
Includes pre-fitted high-flow valve, printed feed lips, and a 1:1 NBR injection-moulded gas router. Ready to run immediately out of the box.
Built using heavy-duty, injection-moulded polycarbonate (or CNC alloy options) designed to withstand direct BB impacts at point-blank skirmish velocities.
Part of Airtac’s swappable modular system, easily switch your magwell base between M4, MP5, drum, or remote feed systems in minutes.
Integrated retention latch drops only 2–3 BBs during quick, tactical magazine swaps.
Equipped with an industry-standard US quick-disconnect fitting for easy coupling with standard HPA remote lines.
Allows you to fine-tune magwell tolerances to eliminate wobble and guarantee smooth feeding across various magazine brands.

Installation requires removing the paddle magazine release on the VMP-2 (a simple single-screw removal process). The main side button magazine release remains fully functional. Removing the paddle allows the M4/MP5 adapter magwell to sit completely flush against the receiver.
Rack your VMP-2 bolt into the rearward position before inserting or removing the HPA adapter. Inserting the unit with the bolt closed can damage the delicate nozzle loading arms.
For flawless high-ROF feeding, we strongly recommend using PTS EPM1/EPM1-S mid-cap magazines for M4 configurations, or CYMA metal mid-caps for MP5 variants.
