BPS: The first thing I wanted to find out about the marker was how fast I could get the BPS (balls per second) up to. The feeling of those first shots was incredible. The marker can deploy those balls with the best of em. I advise players, looking for a high end marker, to look into the Piranha Eforce when they became available.
The Body: The "stacked tube" configuration that we are used to is out with this paintball gun. The new marker features a "sear tripper" design with a vertical feed system. The feed neck is threaded with the Omen/Impulse configuration, which gives you more options when it comes to getting a new feed neck.
The Parts: One feature with this particular marker that jumps out at me is the volumizer, which stores essential air for the valve to draw off of. With this marker you are going to need all the air you can get, with the volumizers' storage you have a better chance to avoid drop off. The sight rail is easily removable.
Buttons: The on/off button is located on the left side of the marker as well as the Sear Release and the charger port. On the left is the three round burst and full auto buttons. The buttons are simple push buttons; the buttons are cleverly placed high on the frame so the paintballer will have limited chance of accidentally pressing a button.
Sear: The Sear Release is located at the back end of the trigger frame and allows the paintballer to reinstall the bolt and hammer assembly without having to turn the Piranha in fire mode. It allows you to pivot the sear out of the way of the hammer to let the hammer slide into the body of the marker. It's just another feature that makes this such a great marker.
Charging: The charging port is directly behind the trigger on the left side. It also features a rubber gasket to keep dust and debris out of the port.
Gas-Thru Grip: Its nothing special as far as looks, but the tapered mill makes fore a very comfortable grip. The front grip is PMI's newer gas-thru grip.
The Grip Frame and Trigger: The grip frame is bigger than the older model Piranha EXT Pro. The frame is a longer, but only by about a quarter of an inch. The trigger pull is very light and the Eforce fires at the beginning of the trigger pull.
Trigger: The frame is made of a polymer plastic, which is very strong, but the main reason that they use it is to keep the price in a respectable range. As far as an aftermarket trigger for this gun, there aren't any, yet.
Trigger: The trigger itself is also plastic with a little hook at the bottom. The Piranha Eforce's trigger is very similar in shape to the IR3's, just not as drastic.
Software: The software package is incredible. With other entry level electronic firing mechanisms, their BPS rate would peak at semi, not with this marker. This marker is godly in a speedball game. It will deploy rounds pretty much when the trigger feels the slightest vibration. THIS THING WILL MURDER all in its way.
Modes of Fire: There is also a three round burst feature and a full auto feature. In full auto the software only allows a measly nine balls per second. With the BPS in semi uncapped, who needs burst and full auto modes anyway?
The Closing Remarks: All in all I had a great day shooting the Piranha Eforce STS 2k4. I feel it is a good sturdy gun and I think that PMI should sponsor a team to compete with these things at the national level - much like what Kingman does for Bad Company. I am almost motivated to play with one next season. Wonder if my teammates will let me
