|The GMG full auto airgun|
The GMG has a 50 round removable magazine, 24" rifled barrel, 4 rail mount locations, non-cycling charge lever, and a 1/8NPT inlet for connection of a remote line from any common HPA/Nitrogen paintball tank. It comes with a top picatinny rail to mount whatever red dot you like, and it also comes with a net bag 'shell catcher' which collects the plastic shell casings as they are ejected. Speaking of shell casings, let's look into how the GMG works.

And just how powerful is the beast? Well, they made a nice graphic which compares the GMG's muzzle energy and firing rate to other airguns and even some full auto firearms. I've attached the image below (click for full view):
Now, what exactly does this mean and why should you care? The 2 colored bars show 2 different performance values for all those guns. The values range from lowest on the left to highest on the right. The top bar shows muzzle energy which is projectile velocity multiplied by projectile mass. This is a good measure of how hard the projectile 'hits'. The second bar is what they call energy flow which is the projectile energy multiplied by the cyclic rate of fire of the gun. In other words, this measures how much energy the gun pushes down range per minute. Other good names for this unit would be "destruction capability", the "FSU factor", or a measurement for the airgun's "funness".
This graphic is important because it shown just how massive of an airgun the GMG truly is. The GMG shoots at a muzzle energy 4X that of the Drozd, and 'flows' energy downrange at 6.5X that of the Drozd. Obviously, the GMG is much more than a typical 'airgun', but still does not approach full auto firearm territory. However, note the GMG is remarkably cheaper than available full auto firearms. The GMG also does not require a background check, $200 tax stamp (required by the Feds for FA firearms), nor are there any restrictions about shipping or taking the airgun across state lines (see our 'airguns and the law' post).
Here's an interesting comparison they did not include on their graphic. How would a semi-automatic 22lr firearm compare in this lineup? Well, using the same muzzle energy as above (400 ft-lbs), and an approximate 2-3 rounds per second rate of fire (typical for non-competition shooters), a 22lr semi-auto would possess an 'energy flow' of approximately 18k (ft-lbs per minute). In other words:
The GMG airgun is almost as powerful as a 22lr semi-autofirearm!!!
So, that's cool.
You can buy one of these wicked GMG airguns right now. A small batch of pre-production prototypes has been made available for purchase on their website. Write them for any special deals, they are cool people.
Gotta run, thanks for reading. Here's a video of the GMG destroying stuff:
