Nerf Modulus Round Counter Kit

If you like to see how fast your darts are and have an extra ammo counter, this is best front attachment for your nerf guns, hands down. It is is also great for modders as well.

The Nerf Modulus Ghost Ops ChronoBarrel is a marvel of Nerf engineering at an affordable price. Not that it is an impossibility, but for what it offers the Nerf community, it was totally unexpected. I start most of my blaster review titles with “Averages XX FPS” (Feet Per Second) because I have a ProChrono Digital Chronograph at home that accurately measures the velocities of the darts fired by whatever is shot through the barrel (it is compatible with standard Nerf Elite darts only: any standard blue, green, white, orange, purple/grey, Starwars themed, Accustrike, and decorated Rebelle darts; be aware that MEGA darts or Rival Rounds/balls are not compatible). With this front barrel attachment you too can get a good idea of how hard your blaster is shooting in FPS or MPS (Meters Per Second). To toggle between the two units of measurement, simply press the + button and - button simultaneously. A great feature with this attachment is that the screen lights-up with a cool orange LED that has an energy-save feature that turns off by itself to save your battery life (1.5 AA x2 alkaline batteries required, but not included) after about 30 seconds of inactivity. If this is not enough, you get an ammo-counter function with it to count down (indicated by an arrow down 🔽) or count up (arrow up 🔼). To set the count down function to the right capacity magazine (or drum) you are using, press the +/- buttons to match the amount of darts in your magazine and it will tell you exactly what you have left in your magazine as you fire darts along with how fast it shot out of your blaster. As you reload another magazine it will start off at the maximum amount you set the previous capacity at (assuming you are using the same size magazines because the device has no way of knowing what size magazine you are loading into the magazine well). To use the count-up function, simply switch the top switch to the far right (🔼) and the rest is self explanatory. Well, there is a reset button (🔁) to restart the count-down or count-up. You can manually turn off the product to save even more energy by switching the main switch to the universal power button insignia. Now you may be wondering how accurate this Chrono-barrel is, and since I have an expensive piece of equipment that measures FPS, I can tell you. Using the Chrono-barrel I fired the shots off with my modified Stryfe into the ProChrono Digital chronograph. The darts passed through both chronographs and the numbers were consistently between 4 to 7 FPS apart, with the Chrono-barrel giving the higher FPS ratings. At first I thought that this was because the barrel was slowing the dart down a bit after the dart passed through to the ProChrono, but when measured independently, the Chrono-barrel still produced slightly higher numbers than what I consider the true rating from the ProChrono chronograph (I trust in my more expensive equipment). But don’t get me wrong, I am still amazed at this little device; the Chrono-barrel still can give great ballpark figures. Why, just now I was able to shoot my aftermarket Caliburn (a 3D-printed blaster known for it’s high FPS) through the Crono-barrel and it registered at 220.7 FPS. To acknowledge such a drastic difference in FPS proves that it is measuring something, and guarantees that you are getting a fairly reasonable ballpark figure to say the least. As far as appearance, it looks great. Like the rest of the Ghost Ops line, it has a transparent shell similar to the plastic of the discontinued “Sonic Series” (a Toys R Us exclusive). The inner barrel carries light from my Ghost Ops Evader very well. There is even a Nerf tactical rail under the barrel allow you to mount a standard Nerf attachment. If anyone else cared to notice, there is an iron-sight in front of the heads-up-display (HUD). It is hard to see because it is also made of clear plastic. In conclusion, this could possibly be the best Nerf attachment in existence. It offers an unprecedented value at a decent cost. You can finally test the strength of your blasters without having to spend a fortune. It looks nice in appearance, is tech-savvy in function, and it has a tactical rail. If ever there was a must-have item for nearly any Nerfer, this has got to be the one. Five Stars from me.

This thing is the best and only useful Nerf attachment. I use it to measure improvements in the speed from modifications. My Son loves the ammo counter.

es un accesorio que debes de tener en tu coleccion imaginate te mide la velocidad de tus dardos te da el contador de cuantos dardos llevas lanzados o le pones un contador ya sea 10 12 o 18 dependiendo de tu mag y te va indicando cuantos dardos te quedan, otros marcas solo para medir el fps son carisimos eso si son mas exactos pero va de 2 a 5 fps de diferencia te comento esto porque ya revise la exactitud y por ende me dejo sorprendido y el precio menos de 200 bueno a mi me toco oferta com tip que lo mas seguro sabes es que no le pongas pilas recargables por que estas son de 1.2v y provoca que no prenda bien el accesorio, forzosamente debes de ponerle las alcalinas las cuales son 1.5v
