An AR-9 80% lower receiver is a component of the AR-9 rifle that is not yet finished. It is not a firearm and cannot be fired as is. It must be completed by the owner in order to become a functioning rifle.

 

This is done by machining the unfinished receiver into the final shape, then installing the parts that make it a complete weapon. The 80% lower receiver is just the beginning – it is the foundation on which you build your custom AR-9.

 

The Modulus AR-9 80% Lower Receiver ‘s new, streamlined design offers tight tolerances for a build that can be great for practically anything, whether the intended uses are for matches in competitive shooting, home defense, or even just what you use to teach new shooters since AR-15s can be a little heavy for some people. We specifically manufactured your AR-9 80 lower for you.

 

We partnered with some of the country's best gunsmithing experts to bring a new version of the 9mm AR-9 80% lower to market. These by-design, USA-made billet aluminum lower receivers are not like any old 9mm AR-15 "box conversion" kit (nobody wants a skinny magazine in a big 5.56 mag well, anyway).

 

Any standard parts that work with an AR15 lower receiver can be used with our AR9s!

80% of our lower receivers are made of aerospace-grade 6061 aluminum from US suppliers. In comparison to other alloys, the material is much easier to mill while being more robust and corrosion-resistant. For an even easier and more successful build procedure, use our 80% lowers with the Easy Jig Gen 3 and Freedom Jig Router.

 

 

 

Engineers took the time to develop these 9mm 80% lowers to work with the standard AR-15 lower parts kit. This lower also works with mil-spec buffer tubes and buttstocks, and factory and aftermarket Glock® magazines and parts, including the popular G-9 Hybrid 9mm bolt carrier group. This lower also works with current AR9 uppers available on the market! 

 

If you want to build an accurate 9mm AR pistol and proudly call it your own creation, this new lower is the ticket. It provides black rifle compatibility and customization potential without breaking the bank. Grab a 9mm AR9 build kit to complete assemble your finished lower.

WHAT IS AN AR-9?

 

The AR-9 is exactly what it sounds like: an AR style rifle chambered to shoot in 9mm. Rather than use a 9mm handgun, many like to opt for the AR9 to have a pistol caliber carbine. A Pistol Caliber Carbine, or “PCC,” is a short, lightweight rifle chambered in any caliber typically found in handguns i.e. 9mm or .45 ACP.

 

AR9’s in particular have a lot of benefits as they have very low recoil, almost non-existent muzzle flash, and are extremely user friendly for beginners. For more experienced shooters they make a great choice for personal defense with their maneuverability.

 

IT’S TIME FOR YOUR AR-9 BUILD

 

We have the best 80% billets on the market and that goes for every caliber. Our 80% AR-9 lower receiver billets are meticulously CNC machined to the highest quality standards out of 6061 aluminum which are also used in the aerospace industry.

 

Remember, these 80% lower receivers are not completed parts which require you to do the last 20% of the work. That’s why 80 lowers are not considered firearms, and why we’re able to ship them straight to your door!

 

 

THE BENEFITS OF AN 80% LOWER RECEIVER FOR THE AR-9

You can buy an AR-9 rifle or you can build one yourself. If you’re still trying to make that decision, then it’s advantageous to consider the benefits of assembling an 80 lower for the AR-9.

 

An AR-9 80% lower receiver costs much less than a pre-assembled rifle. Along with saving money on the purchase, you will also save money in taxes and fees because you won’t have to pay them when buying an 80% lower receiver.

 

Owning an AR-9 80% lower receiver means that you can build your own firearm. This means more than just assembling the parts, though; it is about designing a custom AR-9 for your needs and specifications rather than buying one off of the rack or choosing one that was made by someone else.

 

HOW TO FIND THE BEST AR-9 80 PERCENT LOWER RECEIVERS

When it comes to buying an AR-9 80% lower receiver, there are a few things you need to keep in mind. First, make sure you are buying from a reputable and reliable source.

 

There are many companies that sell 80% lower receivers online, but not all of them are created equal. Be sure to do your research and only buy from a company that has a good reputation and is known for selling high-quality products — like 5D Tactical!

 

Another thing to keep in mind is the type of lower receiver you are buying. There are two types: forged and billet.

 

Forged receivers are made from a chunk of metal that is shaped into the receiver using a forging process. Billet receivers are made from a single piece of metal that is cut into shape using a CNC machine. Billet 80% lower receivers are generally considered to be more precise than forged ones, but they tend to cost more.

 

It can be exciting and fulfilling to build your own AR-9 carbine with your own hands. For more information on the best AR-9 80% lower receivers on the market, reach out to the 5D Tactical team today.
