I dont think it is necessary for players to know this. For one they won't understand or will only focus on the numbers.
If you know the freeze (low,medium,high), spread, reload time, clip size, accuracy, ROF...That's all. In descriptions you can find these only difference is it is in words not numbers. If the description said Freeze: 0.5...None would become wiser but if one said Freeze: Medium...You get an idea of how the gun would function.
