Polymer80 AR-15 and .308 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.

Our polymer lowers weigh just 0.3 pounds. Once assembled, they reduce weight by around 50% compared to traditional aluminum lowers!

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.
