The Polymer80 P2 IN-00277 Skeleton Lower Receiver delivers a precision-engineered foundation for left-handed shooters seeking a lightweight, high-strength platform. This stainless steel skeleton design reduces overall weight by 30% compared to traditional solid receivers while maintaining structural integrity under high-stress conditions.
What Makes This Different
The skeleton cutout pattern eliminates unnecessary material without compromising strength, creating optimal weight distribution for extended shooting sessions. CNC-machined from premium stainless steel, this receiver features enhanced corrosion resistance and dimensional stability that exceeds mil-spec tolerances. The left-hand configuration provides natural ergonomics for southpaw shooters, with reversed controls and ejection patterns optimized for left-handed operation.
Key Features
- Left-hand specific design with reversed controls and ejection port
- Skeleton cutout pattern reduces weight by 30% while maintaining strength
- CNC-machined from 416 stainless steel for corrosion resistance
- Mil-spec dimensions ensure compatibility with standard components
- Enhanced trigger guard geometry accommodates gloved operation
- Precision-drilled pin holes with ±0.001" tolerance
- Serialized and ready for FFL transfer
Field testing demonstrates consistent performance across temperature ranges from -40°F to 140°F, with zero dimensional changes affecting function. The stainless construction resists saltwater corrosion, making it suitable for maritime environments and humid climates. Competition shooters report improved balance and faster target transitions due to the reduced reciprocating mass.
