Product Overview
The Polymer80 RL556V3 – RHINO 80% AR-15 Lower Receiver and Jig Kit Bundle is a complete starting point for the experienced firearms enthusiast looking to undertake a custom build project. This bundle includes an 80% lower receiver blank, machined from high-strength polymer, and the specialized RL556v3 jig required to complete it. Designed for the builder who values a lightweight platform, the finished lower is intended for semi-automatic AR-15 pattern rifles. Its primary use is in creating a personalized, ultra-lightweight rifle for sporting, recreational shooting, and home defense applications, where reducing overall weight is a key consideration. Available in Flat Dark Earth and other colors, it offers an aesthetic choice to match your build vision.
Key Features
- Weapons-Grade Polymer Construction: The receiver is molded from a reinforced, glass-filled polymer compound designed for durability and impact resistance, resulting in a frame that is significantly lighter than aluminum counterparts without sacrificing essential strength.
- Complete RL556v3 Jig Kit Included: The bundled jig is precision-engineered to guide the drilling and milling operations required to finish the 80% lower, providing the necessary templates and fixtures for a correct completion when used with the appropriate tools and skills.
- Ultra-Lightweight Design: The finished polymer stripped lower contributes to a markedly reduced overall rifle weight, ideal for building a handy, easy-to-maneuver firearm for extended carry or dynamic shooting sports.
- Standard AR-15 Compatibility: Once properly completed, the lower accepts standard AR-15 parts kits, fire control groups, upper receivers, and magazines, ensuring broad compatibility with the vast ecosystem of AR-15 components.
- Flat Dark Earth Finish: The integrated color (also available in Black, OD Green, and Ghost Gray) provides a durable, non-reflective matte finish suited for a variety of environments and personal preferences.
- 80% Lower Status: As an unfinished receiver blank, it is not classified as a firearm at the point of sale, transferring directly to the end-user. The completion process is the sole responsibility of the builder, who must comply with all federal, state, and local laws.
Performance & Applications
The completed Polymer80 RHINO lower is engineered for specific niches where its polymer construction offers distinct advantages. Its performance is tied directly to the quality of the completion work and the components used in the final assembly.
Ultra-Lightweight Hunting & Varmint Rifle: By pairing this lower with a lightweight upper receiver, barrel, and stock, builders can create an AR-15 that is exceptionally easy to carry over long distances, reducing fatigue during hunting excursions or pest control operations.
Dedicated Training & Recreational Platform: The reduced weight makes for a less cumbersome rifle during extended range sessions or training courses, allowing shooters to focus on technique. It serves as an excellent base for a .22 LR conversion build for affordable practice.
Custom Home Defense Configuration: For a home defense rifle where maneuverability in tight spaces is paramount, the lightweight characteristic of a build using this lower can be a significant benefit. It should be completed and assembled with proven, reliable components intended for defensive use.
