This Airsoft Gun is an M4 Platform replica that is based around a HPA System, which makes it very different to typical AEGs. The Gun is powered by a bottle of High Pressure Air which is installed in place of the Buffer Tube (at the Stock), and then controlled by an Electronic Trigger Unit which will release a small burst of air to launch the BB. This is a much more cost effective and less headache-y way of getting into HPA Airsoft Guns, as there is minimal setup required.

As with all high end TIPPMANN products, this Airsoft Gun is built to a fantastic standard, using mostly Alloy for the externals. The Outer Barrel Assembly, Handguard, Receiver and Fire Controls are all Alloy, whilst the Flash Hider, Pistol Grip, Iron sights and Stock Assembly are a high density Polymer. The Flash Hider will unscrew to reveal a 14mm CCW Thread underneath which can be used to installed Suppressors, Tracer Units and other Muzzle Devices. The licensed M-LOK Handguard is absolutely solid and will happily accept either M-LOK accessories or Rail Adapters to use 20mm RIS attachments. The top of the Rifle has a full length 20mm Rail which can be used to install Sights and Scope, but comes out of the box with a set of Flip Up Iron sights attached. The Trigger is an Electronic Trigger Unit, but also has a resistance spring behind the Trigger so that it forcible returns to the neutral position.

To get the TIPPMANN Omega-PV HPA working, you simply need to screw the HPA Bottle (hopefully filled) into the rear of the Receiver (a sharp hiss will be heard once the connection is made). The Stock Guide can then be lifted up and the actual Stock piece installed over the HPA Bottle, which will then work like any multi-position M4 Stock. A 9V Battery should then be installed inside the Pistol Grip, a Magazine installed and the Gun will work. The FPS is adjusted when the bottle is removed, by turning a 5/32" wrench at the back of the Receiver, making a clockwise turn to REDUCE velocity, and a counter clockwise turn to INCREASE velocity. The Rate of Fire is controlled by the Electronic Trigger Unit, and is adjusted by following these steps:

Hold Trigger
Turn Fire Selector to 'Safe' position
Release Trigger when LED flashes
When LED Flashes, press Trigger to adjust ROF
Turn to Full Auto Mode
You can see what ROF option you have applied by looking behind the Trigger Unit and noting the colour of the LED Status Indicator. Green for 10RPM, Orange for 20RPM and Red for 25RPM. The HOP Unit is a Rotary design which can be adjusted as per any standard M4, by pulling back on the Charging Handle and turning the Rotary Dial behind the Mock Bolt and Dust Cover.
