Polymer80

Polymer80

The polymer 80% gunsmithing kit represents the newest, easiest way to build a factory-spec handgun or polymer AR-15 at home. These 80% pistol frames and 80% receivers include American-made, affordable units with the necessary jig and tooling to cut and drill your blank, turning it into a firearm that's ready for final assembly.

Available Polymer80 Pistol Kits

Polymer80 pistol kits are compatible with gen 3 Glock® components in the corresponding caliber and frame size. Select one of the available 80% frame kits or pistol build kits by Glock® platform compatibility:

  • PF940C is compatible with Glock 19, G23, and G32 handguns.
  • PF940v2 is compatible with Glock 17, G22, G24, G31, G34, and G35 handguns.
  • PF940SC is compatible with Glock 26, and G27 handguns.

Completing each frame or receiver requires drilling a few holes and removing excess polymer material using the included bits. These steps can be completed with basic hand tools (all you need is a vise, a Dremel, and some files). Little to no experience is required, thanks to easy-to-follow instructions! Once completed, simply pair your pistol frame with the appropriate Gen 3 Glock® barrel, slide, and parts kits, and hit the range in a single day.

Polymer80 AR-15 and .308 80% Lowers

We're also excited to introduce polymer 80% lower receiver options for the AR-15 (5.56/.223) and .308 (DPMS Gen 1, LR-308)! If you've been wanted to shed weight and build the lightest AR-15 or .308 rifle possible, you've in the right place.

First-timer? This guide explains how to complete a polymer 80 percent lower.

These polymer lowers weigh just 0.3 pounds. Once assembled, they reduce weight by around 50% compared to traditional aluminum receivers! Our friends over at Polymer80 took the time to ensure these lowers are capable of handling high-powered rifle rounds. Many customers have already built their black rifle or pistol using polymer, to great effect.

Federally Legal to Buy and Build

Polymer80's frames and lowers are not considered firearms under federal law. The ATF Recognizes these units as receiver blanks, defined as un-fabricated and non-functioning firearm parts. They do not require an FFL to buy or own, nor do they require a background check under federal law. Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.

 

Your custom build awaits.
