Sean T. Verified Buyer –
Seriously if you have a C8 just buy this. I just collimated my scope pretty well within a few minutes. With a screwdriver it took me ~hours. You have to carefully look at the front of the scope every time when using a screwdriver so you don’t put the screwdriver into the corrector plate! But with fingers it’s safer, easier, and faster. So glad I f
inally bought this kit.
