This is a great product, can be used with any paint due to the sizers. Makes the marker quieter. Makes the marker shoot dead on if you size the paint right. The only down fall Ican find is that after you get a paint break in the back of the barrel where the sizer is, it can be a pain to get it out due to it being oily. Ya I know really a stretch to find a complaint. I would however like to see this in a solid barrel instead of the 2 peice.
Conclusion:
Want to be the dude that does the head shots then get this kit
