But, if you are thinking about going a longer range then go for 5x to 8x.

Objective Lens

The bigger the objective lens the better, since it will enhance the clarity and brightness of the scope. But that can work against your favor, making the scope too heavy and expensive. For your S&W M&P 15-22 you can use a 30mm to 44mm objective lens to get better sight without making it too heavy.

Lens Coating

Coating your lens is necessary to get a better view, especially in a low light condition. You will find different types of lens coating in the market. But going fully coated lens will be a standard option since it will coat all the external glass and will not cost too much.
