[Syndakit]

That's kind of the idea to the Z-kit... one size to be close to your barrel window...

I use krazy glue, the non run gel kind. I haven't had the same issue, mind you I am very careful while sanding.

And I understand the time complaint, but if you work 70 hours a week and $40 is a lot of money, you need a new job bud lol.

Edit: I take the time complaint back, it literally takes half an hour tops to do this, not including curing time lol.
