An 80% lower receiver is exactly what you'd think it is, a lower receiver that is 80% complete. By leaving the lower receiver at 80 percent, it can be shipped to most states without the need for a background check. This is due to the fact that it is not viewed as a complete firearm. It is then the responsibility of the purchaser to complete the lower receiver.

80% lowers are made in a variety of materials: forged 6061-T6 aluminum forgings, 7075-T6 aluminum billets, injected molded polymer & many others.

80% lowers are offered in a range of platforms including AR-15, LR-308/AR-10, and Glock compatible 80% frames.

Select 80% lowers may include tools such as jigs and bits, if the one you've selected does not include these components you can find a selection of tools and jigs that can be purchased to complete your 80% build project here at Omega Tactical Distribution.

Here at Omega Tactical Distribution, our team has put together combinations of related products for AR-15, LR-308, Ar-10 & Glock 80% lowers.

What is an 80% Lower Receiver?

An AR is made up of two receivers, the Upper and the Lower. The lower receiver is the lower half, the section where the serial number is listed. In essence the lower receiver is that part of the AR 15 that makes the firearm a firearm.

An 80 percent lower receiver is a lower receiver that has not been deemed a firearm by ATF standards. An 80 percent lower receiver is the most complete a receiver can be without the ATF considering it a firearm. As a result of it not being considered a firearm and is incomplete, there is no serial number or need for a background check. Whichever 80% you have chosen, once you have begun the process of drilling even to the smallest degree, your 80% is now considered a firearm even if you are only 81% complete.

Types of 80% Lowers?

Here at Omega Tactical Distribution, we offer the 3 most popular types of 80% lowers: AR-15, AR-10/LR-308, & Glock Compatible Frames.

AR-15 - these will work with all AR 15 upper receivers that are on the market (unless there are required proprietary components for either the upper or the lower)

AR-10/LR-308 - While there are some subtle differences between the two platforms, they are very similar. Certain parts are not compatible between the AR-10 and the LR-308. So when you are considering doing an LR-308 build, the MOST IMPORTANT thing you can do is take special precautions and do your research. This will ensure that your upper receiver will be compatible with your 80% lower.

Glock Compatible - Recent years these 80% frames have grown increasingly in popularity, due to the fact that they can be purchased in a variety of calibers, sizes, and most importantly colors. Allowing for the most customizability in your firearm.

There are many firearms platforms that accommodate an 80% Lower receiver, the ones provided above are just the most popular that we provide.

What materials are 80% lowers made from?

80% lower receivers are mainly made from either aluminum or a polymer compound. The aluminum 80 percent lowers can come in either forged and billet construction. Depending on your preference we have options for both. One of the benefits of purchasing a polymer 80 percent lower or frame, is they typically come with the necessary jigs and bits required to complete the lower.

Building Processes for an 80% Lower?

The building process involves some work on the purchaser's end. You will need to drill the necessary holes and then either mill or drill out the remainder of the material that needs to be removed, depending on what equipment you have or your preference. Once the drilling is done you will need to just assemble the remaining components and now you have a complete lower for your firearm.

What parts are needed to complete your 80% Lower?

In order to complete an 80% lower, you are going to need a Lower Parts Kit (LPK) as well as a Buffer Tube Kit. If the purchaser is uncertain what parts are needed and compatible, a Finish Your Build Kit can be purchased with all the required parts to complete the entire lower receiver. Once the lower has been fully completed it can be paired with any of our Pre-Assembled Upper Receivers, and will be ready to take to the range.

For the Glock 80% frame, a frame parts kit is needed to complete the frame. Once the frame has been completed, you will be able to pair it with a built-out slide.

What tools are needed or recommended to complete an 80% lower?

There is no one correct answer to this question, as many people have their own preferences and can be done with a wide range of tools. Simply you will need the drill bits of the appropriate sizes, a jig to ensure the holes are lined up correctly, and a power drill. Other tools that are commonly used are routers with bits as well as files, these are used to help clean up the receiver and make the finished product look cleaner. Keep in mind if a billet 80 percent is purchased these may not be compatible with the jigs additional tools and work may be required to complete it. Be sure to check compatibility of all products.

What states cannot have an 80% lower shipped to them?

Please consult our Product Restrictions Page for the information about states that have restrictions on products, including 80% lower receivers.

Is it legal to build an AR with an 80% lower?

According to the Bureau of Alcohol Tobacco Firearms and Explosives (BATFE) is legal for an individual to manufacture a firearm for personal use. If the intent is to sell the firearms that are manufactured then a Federal Firearms License (FFL) is required. So currently it is legal (in most states) to build an 80% lower into a complete firearm for personal use.

"No, a license is not required to make a firearm solely for personal use. However, a license is required to manufacture firearms for sale or distribution. The law prohibits a person from assembling a non–sporting semi-automatic rifle or shotgun from 10 or more imported parts, as well as firearms that cannot be detected by metal detectors or x-ray machines. In addition, the making of an NFA firearm requires a tax payment and advance approval by ATF.

[18 U.S.C. 922(o), (p) and (r); 26 U.S.C. 5822; 27 CFR 478.39, 479.62 and 479.105]”
