This is my first pair, mounted on my 1.5-5 VXIII for my .375 HH Encore. What I like about these covers is they use magnets and an "O" ring to keep out dust and moisture. It's like having a 2 stage closing system, first stage is the magnet which partially holds the flaps closed so when you open them it can be very quiet but you could aslo snap them closed over the "O"ring and it is more secure requiring a little more effort to open but also keeping out any dust and moisture. Awesome covers!! I'd like to see some see thru covers in this configuration. Good Hunting!
Pros: 2 levels of closing - allows for very quiet opening
