80% Glock

At 80 Percent, Glock Pistol products are always available

If you’re looking to build a new 80%, Glock® platform based builds are an extremely popular choice. Our Glock® parts compatible pistol lowers are easily finished at home with tools you likely already have available, and no special skills or experience are required. Every 80% Glock®-compatible pistol will universally accept all OEM and aftermarket Glock® Generation 3 components, so you can customize your perfect Glock®-compatible build.

80% Glock compatible parts allow you to build your own G17- or G19-style handgun without having to deal with the red tape involved in most firearm transactions. All of our 80% Glock compatible lower kits are made with precision materials that are compatible with aftermarket and factory Glock components that allow you to build your own firearm at home.

Why build a Polymer 80% Pistol?

Plenty of reasons! Whether it’s a project for fun, for self-defense, or to ensure your Second Amendment rights, there are an abundance of reasons on why you might want an 80 percent Glock kit:

NO Registering an 80% Lower NO FFL Required, Ships right to your door 
NO Transfer fees like a typical firearm     

 

Finished lower receivers and frames are considered a handgun under FFL laws, but 80% lowers and frames are not since they are non-functional. They are also not considered a firearm under federal law or the ATF. So, you can order the separate components to construct your own Glock style frame without going through the paperwork and waiting periods associated with finished handguns. 

As far as manufacturing and build go, our aftermarket 80% Polymer Glock compatible lowers are ultra-light and made out of quality weapons-grade polymer, and are the most affordable 80 lower on the market.

Choosing the Right Polymer Eighty Percent Pistol:

Whether you’re looking for a carry gun, a race gun, or a pistol that can do-it-all, we offer multiple different polymer 80% pistol sizes to fit everyone's needs.

What Comes With a Glock Lower Parts Kit?

The Glock lower parts kit contains everything you need to build your Glock at home:

  • Trigger Assembly

  • Ejector 

  • Slide Lock Lever

  • Trigger Housing & Connector

Are 80% Glock Style Pistols Legal?

The Supreme Court’s recent ruling allows the ATF to regulate certain kits under its 2022 frame or receiver rule. Be sure to check your state laws, as some states have additional restrictions on 80% Glock-style pistols and build kits. 

While SCOTUS's decision keeps the ATF’s rule in place, it also left the door wide open for continued legal challenges. That’s exactly what we’re doing. 
Your support means everything. Every order helps fuel our legal battle to restore your right to purchase 80% pistol frames, just like it used to be.

We’re not backing down. We’re pushing forward harder than ever.

 

Whatever you choose, all products are backed by a lifetime guarantee!
