Top 5 Features
- 3 modes of cocking
- Unique design
- No external air lines
- Internal regulator
- Cocker barrel threading
The Metadyne Thumper has a variety of features. What stands out the most is that it can be cocked in a few different ways. This sets it apart from the rest of the paintball pumps out there. The Metadyne Thumper can be cocked via the barrel, the side of the marker, or the back of the marker.
This marker is currently available in blue, red, black, digital snow camo, and snow camo.
Cocking the Metadyne Thumper
Most pumps need to be pulled towards you to load a paintball. To load a paintball into the Metadayne Thumper, you pull the barrel out. There's no pump handle, the barrel itself is pulled to load the paintball.
On the side of the marker is a lever where you can place your thumb. By pushing it out with your thumb, you can cock it. It's ambidextrous, so it can handle cocking on the right or left side.
On the back of the gun is another spot where you can cock the gun with your thumb. Just push it in with your thumb and it will load a paintball.
One of the problems with a traditional pump marker is that it can be difficult to pump in a tight spot. Cocking via the side or back of the Metadyne is much easier to do in tight spots.
Unique Design
Many pumps out there are based on just a few designs. The Metadyne Thumper is the first of it's kind, and has a completely unique design. You can see that there aren't any external hoses. Their is a vertical ASA where you can screw in 12 gram cartridges or a small CO2 tank such as a 4 oz.
To use a bigger tank, you would need to install a bottomline adapter to use a bigger HPA or CO2 tank. In a bottomline setup you would have an external hose connecting to the vertical air adapter.
With the design of the marker and the ball detent, it's impossible to double feed it. When the paintball is loaded, it drops directly down from the feed and doesn't move, so loading another paintball is impossible.
For consistent air pressure there is an internal regulator. This is a nice feature for helping to maintain a steady FPS. Consistency after all, helps with accuracy.
Only Use Petroleum Jelly to Lubricate the Metadyne Thumper
Using any other kind of lubricant will ruin the valve. Only petroleum jelly such as Vasoline can be used. Apply a small amount of petroleum jelly in the ASA, gas it up, and shoot it a few times to make it work it's way through the marker.
Lightweight & Compact
It's both small and lightweight. With a Deadlywind carbon fiber barrel installed, it weighs under 2 lbs.
Upgrades & Accessories
Since it is autococker threaded, there are tons of different barrels or barrel kits out there that will fit.
Also available is a 45 grip upgrade, and an open class adapter that accepts CCM threads. The open class adapter lets you install a feed neck and use a hopper if you don't want to play with a stock class setup.
Also available are brass cocking rods and cocking levers to install on the right or left side of the marker.
How it Compares
It doesn't. This is a unique, high-end, pump paintball marker that further sets itself apart with the ability to cock it 3 different ways.
Who Should Get It
Stock class fans that enjoy using 12 gram cartridges and 10 round feed tubes should get it. Paintballers who appreciate one-of-a-kind paintball markers and enjoy pump play should get it.
