There is still another problem though!

With so many routers out there, making a buying decision can be difficult. Well, worry not! In this guide, we’ve listed some of the best 80 lower available.

Here they are!

Router for 80% Lower: Buying Guide 

After going through our reviews, you’ve probably found the best router for 80 lower already. But, if you’re still finding it difficult to make a decision, you’re not alone. Considering the number of models available, choosing a milling tool isn’t simple. 

That’s why you need to consider the following factors before you settle on any 80% lower router; 

Router type 

There are different types of 80% lower routers that you can choose from. They include; fixed base, plunge base, and combo routers

Fixed-based routers are ideal for beginners since they’ve got a secure mechanism. This allows you to fit them over any bench or router table. They’re suitable for projects that require accuracies when cutting straight lines. 

With a fixed-based router, you cannot adjust the depth once you set it over. Therefore, it maintains the depth throughout the tool’s usage when handling a certain task. For this reason, you cannot use them for over-cutting or gouging tasks. 

Plunge base routers can handle various tasks, making them ideal for professionals. With this type, you can change the depth settings while using the tool. Unlike fixed base routers, you’ll need some skills to use them. They’re an excellent option for making center cuts on various surfaces. 

If you regularly change bases while working on your 80% lower, consider buying a combo router. As you may have guessed, this tool contains both plunge and fixed bases. 


The best router for milling 80 lower should be powerful enough to drill or mill through the metal. Otherwise, you’ll have a hard time when working on tough and resilient material. With that in mind, avoid choosing tools that have less than 1HP. 

Motor speed 

Speed is another important factor you should consider when selecting a lower router. In general, different tasks/ materials require different speeds. Therefore, you should choose a model that has a variable speed control function. That way, you can adjust the speed, depending on the project you’re working on. 

Motor speed is rated in rotations per minute (RPM). This describes the number of turns or rotations the device can make per minute. That said, when choosing an 80 lower router, choose a tool with an RPM range of about 10,000 – 30,000. 


Hopefully, you’ve now found the best router for 80 lower that’s ideal for your drilling and milling needs. All products on the list provide reliability, durability, as well as optimum performance. Also, they’re easy and comfortable to use, and most of them come from reputable manufacturers.

Remember, your lower may not function properly if you don’t finish it with precision. Thankfully, routers in this list can drill and mill through your lower effectively. So, don’t hesitate to choose the one that meets your project needs! 

Frequently Asked Questions 

#1. Can you mill an 80 lower without a jig?

Jigs make finishing an AR-15 lower faster and easier. However, you don’t necessarily need one when milling through the lower. Instead, you can memorize the dimensions you want to drill and mill them with a lot of precision. This may be a little difficult for beginners, but with enough practice, it’s achievable. 

#2. Can I use a drill press to finish an 80% lower? 

Yes. You can either use a router or a drill to finish an 80 lower. One drawback of using a drill press though is that it’s can be a difficult and tedious process. Also, it’s not ideal for milling, yet finishing the lower will involve some milling. 

#3. What extra accessories does a compact 80 lower router comes with? 

First, the router should be compatible or come with different base designs. Moreover, it should include guides, wrenches, router bits, and LED lights. 

#4. Why do you need a jig when finishing an 80% lower receiver? 

An AR-15 jig allows you to finish your 80% lower with accurately drilled pinholes. Also, it enables you to mill the fire control cavity for various components. 

#5. Can I serialize my 80% lower? 

Since an 80% lower isn’t a firearm, registration or serialization isn’t required. However, this may not apply in all states. For instance, in California, owners should serialize their lower receivers before drilling and cutting.
