Criteria for Choosing the Best Scope for M4

Regardless of whether you are purchasing the first M4 scope or you need to get a newer optic, below are some of the key features you should take into consideration before purchasing an M4 scope.


Choosing a scope with the right magnification can help you push your M4 to its full potential. Generally, your intended usage and how far you will be shooting at determines the most appropriate scope magnification.

A fixed power scope is more suitable for taking shots at constant ranges in close and medium quarters. On the other hand, it is best to get a  variable power scope so you have the flexibility to take shots at different ranges. Typically, any model with not more than 10x magnification power will do.

Type of Scope

Given that the M4 is one of the most versatile rifles out there, there are plenty of scopes that you can pair it with and achieve or exceed your expectations.

Generally, you can get an LPVO, red dot sight, variable power scope or thermal scope. It all trickles down to the intended usage and your preference.

Lens Coating

Get a scope that employs fully multi-coated lenses or fully-coated lenses. Such a scope will enhance light transfer and minimize glare and loss of light via reflection. Glare reduction makes aiming simpler when you are shooting in excess light settings. Additionally, optimal light transfer guarantees bright and clear image views even in low light settings.


No matter the application that you will be using the M4 for, it is best to get a scope that can handle rain, fog, snow, mist and any other weather element. The scope should be purged with either argon or nitrogen to counter fog build up internally and externally. It should also be sealed to keep moisture, dust, dirt and any other debris from entering the optics.

Eye Relief

Ideally, the scope you get should have an eye relief that is not less than 3.5 inches. The M4 kicks hard when fired and can result to eye injury  if the scope you are using has a poor eye relief. A scope with a generous eye relief also aids in faster target acquisition and maximizes eye comfort with or without eyeglasses.


The M4 is an ultra-versatile rifle that performs in virtually any condition. To achieve its fully potential, you will need a scope that is well built to weather anything you and nature subject it to.

With so many options out there, go for a model that is made from premium grade materials such as aluminum. The scope you get should also be shockproof to withstand rough handling.


Weight is another important factor that you should take into account. Given then the M4 emits heavy recoil, it is best to get a scope with an ultra-lightweight design. It will disperse the recoil effectively and optimize durability. A light scope is also easy to carry, simpler to mount and convenient to shoot with.
