If you're interested to know how a machinist does it, here's how I cut over 2 dozen lens protectors;
For round protectors
1) go buy the adjustable rotary cutting tool specifically made for cutting holes out of thin sheets. (not a hole saw, but that works too I guess)

If you do need to glue a protector in, use a FLEXIBLE glue, like hot glue. DO NOT use superglue or krazy glue. Firstly, krazy glue has a stupidly low surface tension and it'll get all over the polycarbonate lens. Second, as soon as a BB hits it, it'll break loose.
I thought about rotary tool. You need to buy a perfect diameter fit, or whole set ($$). Secondary, center drill must be removable. You never know till you buy and open package.

Glue choice, eh... you are correct, I will add hot glue on the side to hold it.

Should this be in FAQ or sticky? Or am I the only one?
