This is the Viper Predator Pro MT (Micro tune) that I have on my bow. No plastic....and it's the brightest sight I've seen. I have the .019 top and 2nd pins.....and .010 3rd and 4ths.

I took off the spott hog Hunter hog it to put this sight on. I'll sell it for $100 if you'r einterested in it, though (w/ light kit....+ shipping).

The Viper is the best I've seen.
