Smith & Wesson M&P AR-15 Customizable Lower Parts Kit - Complete Kit (Excludes Grip)$34.79
Availability: In Stock
Building an AR-15 from scratch starts with a solid foundation, and the Smith & Wesson AR-15 Complete Lower Parts Kit gives you all the internal components needed to assemble a functional lower receiver. If you've got a stripped lower receiver sitting on the shelf and a stock assembly ready to go, this kit fills in everything between—the springs, pins, disconnectors, and trigger assembly that turn raw aluminum into a working rifle platform. It's the smart choice for builders who want OEM-quality parts without assembling them piecemeal.
This is genuine Smith & Wesson engineering, meaning the tolerances and materials are designed to work reliably in the M&P ecosystem. Whether you're building your first AR or your fifth, having a complete, matched kit eliminates the guesswork of sourcing compatible parts across multiple suppliers. It's one order, one box, one set of instructions—and you're ready to move forward with the build.
The kit does require a stripped lower receiver and your choice of stock assembly; neither is included here. If you're starting from absolute zero, those are two separate purchases. But if you already have a lower and a buttstock sorted, this kit gets you to the range faster than hunting down a dozen individual components.
You'll need a stripped lower receiver and a stock assembly. This kit provides everything else that goes inside the lower—trigger assembly, springs, pins, and all the internal components required to make the lower functional.
This is a Smith & Wesson M&P kit designed for M&P AR-15 platforms. Compatibility with other lower receivers may vary, so verify fitment with your specific stripped lower before assembly.
Lower parts installation typically requires basic tools and some familiarity with AR-15 assembly. If you're new to building, consider consulting assembly guides or seeking help from someone experienced with AR builds.
The kit includes all internal lower parts: trigger assembly, disconnector, hammer, sear, springs, pins, and associated components. It does not include the lower receiver itself or a stock assembly—those are purchased separately.
