Polymer80 LR-308 80% Lower Receiver

About this product

Polymer80 LR-308 80% Lower Receiver Overview The Polymer80 LR-308 80% lower receiver represents a precise engineering solution for builders focused on large-frame AR platforms. This component is designed for the .308 Winchester/7.62 NATO pattern, offering a lightweight polymer construction that reduces overall rifle weight without compromising structural integrity. As an 80% receiver, this unit requires final machining of the fire control pocket and trigger pin holes before it can be assembled into a functional firearm. The polymer80 lr-308 80% lower receiver is compatible with standard DPMS-pattern upper receivers and parts kits, providing a solid foundation for custom long-range or hunting builds. Each receiver is manufactured from high-impact, glass-reinforced polymer to meet the demanding specifications of the AR-308 platform. Features & Specs This polymer80 lr-308 80% lower receiver is crafted from proprietary Nylon 6/6 polymer with 15% glass fill, offering a balance of weight savings and dimensional stability. The receiver features an integrated trigger guard, flared magazine well for rapid reloads, and a rear takedown pin detent channel that is pre-drilled and tapped. All critical jig-indexing points are clearly marked for the drilling and milling process. The unit is designed to accept standard AR-308 fire control groups and buffer tube assemblies. Material: Glass-reinforced Nylon 6/6 polymer with UV stabilizers Platform Compatibility: DPMS-pattern LR-3
