The .300 BLK cartridge is a great alternative to 5.56, and one that will let you use many of the same parts with a 5.56 rifle in the build.

That being said, it also offers numerous advantages over 5.56 just from a standpoint of performance. 

Here are some of the best reasons that a .300 Blackout build kit represents a great alternative to 5.56 (and where you can get one).

Arguments Based on Caliber

First, there are numerous arguments that a .300 BLK rifle is a suitable alternative to 5.56. Let’s take a closer look at some of these: 

• For one, it offers considerably more stopping power without producing too much more recoil. This makes it ideal for hunting and defensive applications at appropriate ranges. 
• The .300 BLK produces a wider wound channel, which gives it an edge there as well.
• The .300 BLK also performs very well from a short barrel, as well as suppressed. This makes it superior to 5.56 for ARP and SBR builds.
• The two cartridges are very similar, so you can use a lot of the same parts from a 5.56 rifle with a .300 BLK rifle build.
• There are some really great supersonic loads that produce not only little noise but also relatively little recoil.

Now, in the spirit of fairness, we have to mention just a few things. 

• .300 BLK is harder to find and more expensive. 
• It does not perform well at longer ranges. 

These are two of the big drawbacks. But, if you are comfortable with the range, you can also load your own ammo to save on the chambering, despite the fact that it is a bit more rare than 5.56 

In Favor of the Build Kit Route (Regardless of Caliber)

In addition to the caliber-based arguments, there are plenty of good reasons to build with a .300 Blackout build kit rather than buying all the parts piecemeal and doing it that way. Here are some of the best of them:

• A .300 BLK build kit (if it is a complete build kit) will come with all of the parts you need to assemble a functioning rifle minus the lower receiver. 
• You will have peace of mind that all of the components in the kit are compatible with each other. 
• It can save you time since you won’t need to buy all of the parts separately. 
• As an alternative to buying a finished rifle, a build kit will give you pride of ownership, let you practice working with your hands, and prove educational as well.
• A build kit can be more convenient than buying all of the parts separately. 

Now, just as there are shortcomings associated with the caliber, there are some things you should be aware of if you build from a kit. 

For one, you will still need to get a lower receiver. For another, while it can save you some effort, you will still need to invest time in assembling the rifle.

Overall, it can still prove an educational and enjoyable process, however.
