300 Blackout Scope: FAQs

How to pick the Best Scope for 300 Blackout?

Rule of Thumb

Did you know that the 300 Blackout was initially designed to be a suppressed weapon? It is known as the only semi-automatic cartridge that can cycle super and subsonic rounds without the need to change or remove anything but the rounds themselves.

While the 300 Blackout is known to be such a versatile cartridge, not all scopes can keep up with it. Hence, for shooters aiming for long shots, a light magnification is your best bet. On the other hand, a holographic or red dot rifle scope is more preferable for shooters armed with a short barreled rifle or any gun that shoots subsonic rounds.

A Note on Subsonic Ammo

Decide if you’re going to shoot primarily subsonic suppressed, or mainly with supersonic ammunition because this will change the type of scope that you need for your intended use.

You should never hunt or rely on self-defense situations with subsonic ammo. You essentially get the same power level as a .45 ACP cartridge, and that is not enough and a rifle line to take the game with.

If you plan on shooting primarily for target shooting, hunting, or self-defense, there are tons of options on the market for you to take advantage of on your rifle.

How to Properly Mount a Scope on to a 300 Blackout?

The procedure of mounting a scope to your 300 Blackout rifle will pretty much involve the general rules in mounting scopes on rifles in general. First comes the preparation of the necessary tools and workspace, then the actual process of mounting the scope on to the rifle.

Some of the basic tools you need include a scope base and scope rings. Make sure that the latter are of the right height and size. In certain firearms, like a bolt-action rifle, you will notice that a base is already built into their upper receivers and some can even come with a set of scope rings as well. Note that the upper receiver is basically the top part of the receiver assembly. You may also use a one-piece scope mount if that’s what you prefer.

Once you have your tools ready, it’s time to prep your rifle. Ensuring that your firearms have no load before mounting a scope should be a no-brainer. At the same time, you may refer to the instruction manual that came in with your scope to make sure that you’re mounting it properly.

Now, the actual mounting of the scope will require you to install the base first unless your rifle has a built-in base on its upper receiver. Then, it’s time to install the rings and position the scope in place. After doing so, you will need to adjust the reticle to make sure that everything is aligned. You may need to move the scope back and forth before getting it right.
