Strike Industries AR-10 Enhanced Lower Receiver Parts Kit (Less Trigger/Grip) - SI-AR10-E-LRPLT - UPC 793811765953
Product Description
The Strike Industries AR-10 Enhanced Lower Receiver Parts Kit (SI-AR10-E-LRPLT) is a comprehensive, duty-grade upgrade package engineered specifically for custom large-frame AR-10, LR-308, and SR-25 lower receiver builds. This kit includes all the critical enhanced small parts, springs, and detents required to assemble a high-performance AR-10 lower—intentionally omitting the pistol grip and fire control group (trigger, hammer, and disconnector) to give builders complete freedom when integrating custom match-grade triggers and ergonomic grips.
Tailored to solve common fitment and operational challenges found across large-frame .308 platforms, this kit features Strike Industries' signature enhanced components. Highlights include the Shift 2-in-1 Extended Pivot and Takedown Pins for effortless tool-less breakdown, the Hex Ambidextrous Safety Selector (configurable for 60-degree short-throw or standard 90-degree activation), an Extended Bolt Catch for aggressive tactile engagement, and an Ultra Light Enhanced Magazine Catch Button.
Precision-machined from high-strength carbon steel and lightweight 6061-T6 aircraft aluminum with severe-duty black oxide and anodized finishes, the SI-AR10-E-LRPLT ensures crisp mechanical function and long-term durability. Complete with all necessary AR-10 specific detents, heavy-duty springs, anti-rotation trigger/hammer pins, and a buffer retainer assembly, this kit elevates your large-frame lower build well beyond standard GI specifications.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for DPMS-pattern and Armalite-pattern AR-10 / LR-308 / SR-25 lower receivers. Note: Does NOT include a pistol grip, pistol grip screw/washer, or fire control group (trigger, hammer, disconnector). Specifically designed for custom builds utilizing specialized aftermarket AR-10 triggers and grips.
- Verify host lower receiver is completely clean, safe, and bare prior to commencing assembly.
- Install the Strike Shift pivot pin and takedown pin using the included AR-10 detents and springs; verify proper extension depth for your specific lower receiver wall thickness.
- Assemble the Hex Selector Switch to your preferred throw angle (60° short throw or 90° standard), applying a drop of blue threadlocker to the selector screws before torquing to final spec.
