Review on Astro 37401 Universal Gravity Filters by Troy Rotermund

These universal gravity filters will not fit my TCP Global gun (TCP G6600-25). The part that initially goes into the gun is too wide. I really wanted to draw that day and since it was Sunday I couldn't buy the right size filters on site. I filed the wide hard plastic part to fit. I then cleaned it to make sure there were no traces left. Everything worked fine after that, but I didn't need the hassle. Update: I can now mount this filter with no modifications, but I have to push it hard into the gun.
