Polymer80 specializes in manufacturing 80% pistol and rifle frames and components for do-it-yourself firearm enthusiasts. The term "80%" refers to a partially completed firearm receiver or frame that requires additional machining or assembly by the end-user to make it functional.
Polymer80 frames & lowers are made from polymer materials, such as reinforced nylon or polymer blends, which offer durability and weight savings compared to traditional metal frames.
Polymer 80% lowers and frames are the best way to build a factory-spec handgun or polymer AR-15 at home. These receiver and frame blanks are lightweight but tough, and 100% compatible with their weapon platform's retail parts. That makes customization affordable and easy.
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.
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.
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.
Some states require serialization of your P80 frame or receiver before fabrication. Other states have banned 80% frames or receivers, certain firearm parts, and other products we sell. Check your local and state laws, and please confirm whether we can ship to your state before ordering.
