If you love mid-range shooting, you will love this scope. Leupold is an excellent manufacturer that is known for their lens making. They provide great performing optics for an affordable price tag.

The 3-9×40 is a medium-range riflescope with a huge 40mm objective lens. The objective lens gathers a ton of sunlight for the scope to work with. Resulting in incredibly vibrant and vivid pictures. It’s like you are seeing through another pair of eyes that has magnification in them.

While the scope is built like a tank and it performs excellently, it won’t support the M&P 15-22 right off the bat. Because Leupold doesn’t include any mounting accessories with the scope.

You will need to purchase Leupold PRW2 Rifle Scope Rings to pair this with. Make sure to purchase the 1” variant. As the scopes tube diameter is 1”.

ii) Sig Sauer SOR52001 Romeo5 1x20mm Red Dot Sight

Ah, the familiar face! Romeo 5 is one of the most recommended sights when it comes to red dots. Sig Sauer is a brand based in Germany and USA. The merge of two sisters gave us some of the best red dot sights in the market.

The Romeo 5 is built like a tank to survive war-like situations. While you won’t go to a war with the M&P 15-22, it doesn’t hurt to be extra prepared. Jokes aside, the sight is water, fog, and shockproof.

While the 20mm objective lens can be a bummer for some, it still gathers plenty of light to work during the day and night. That’s right, the reticle on this is illuminated. You will need a CR2032 battery that you will find in the box. You don’t need any mounting device as this sight comes with a built-in mounting system.
