I was getting fed up with getting shot in the forehead with the i4 so I dug out my spare tippman valour mask and just popped on the visor and it's a great fit and didn't even need to be modded at all ,just a direct fit .
I'll be at diamond wars this Sunday and I'll test it
Gave it a good testing and it works perfectly .
Keeps the sun and rain off the lens and stops the paint hitting me in the forehead .
Well worth it and has made my i4 a much better mask
