What is an AR-15 Scope mount

The AR-15 is a great rifle for its modular capabilities. Virtually any attachment is accessible to the AR-15 when it comes to stocks, grips, and optics. When it comes to scope mounts for the AR15, there are a few you might want to take a look at.

A scope mount is a device found on many firearms, especially those requiring the use of a scope for long distance shooting. Depending on the size of the scope, whether it is recommended or not, will require a scope mount that is sufficient enough in its design to mount it on to the gun. There are a series of different scope mounts people can use, that either make detachment easier, or the mounting more convenient. AR-15s are equipped with picatinny mounting rails.

Many of the AR-15s most fundamental attachments are designed around the picatinny rail system. And while there are some optics out there that have integrated mounting systems on them, there are many that don’t. These typically end up being scopes that are much larger in comparison to the regular red dots and flip sights. 

When it comes to the effectiveness of an integrated mounting system there is some debate. That is because these attachments may be suited well enough for the picatinny system and really require a better system for mounting to provide the same effect. Scope mounts are made to connect the scope to the picatinny rails on the AR-15.

The scope mounts provide the connection to the picatinny rails without damaging or harming the scope which is often made of sensitive, and expensive materials. Not only does the scope mount help the scope remain securely fastened, it is also pivotal to have one that is to the right dimensions of your scope. 

Why buy a scope mount?

Scope mounts are often bought and sold along with scopes. This has been a common way of buying scope mounts, yet also a method that is not necessarily cost effective. Scope mounts bought separately can actually heavily impact the overall pricing of your build. It is much more cost effective to buy a scope mount separately from the scope, or even the AR-15 you are planning to buy, as these are factored into the prices when you go for the final check out.

Scope mounts come in different shapes, sizes and levels of quality. When you buy a scope mount separately you put yourself in control of the level of quality of your scope mount, ensuring that your mounted scope will remain securely fastened. Or say you have a particular scope in mind, but the scope mount for the scope you have is not correct. You can definitely go get a better scope mount, that mounts differently, yet perfectly for the scope you want.
