AR-15 Parts & Components
The AR-15 is the most versatile and modular firearm platform in the world, prized by hobbyists, competitors, and hunters alike for its "plug-and-play" customizability. Whether you are building your first "black rifle" from a stripped lower or fine-tuning a high-performance competition rig, the right components are the difference between a standard firearm and a precision tool.
Our selection of AR-15 parts covers everything from the "heart" of the rifle—the Bolt Carrier Group (BCG)—to the ergonomic touchpoints that define your shooting experience.
Premium AR-15 Parts & Custom Build Components
With our AR-15 Parts you can build, repair, or optimize your rifle with our comprehensive selection of high-performance, precision AR Parts. Whether you are assembling a specialized custom AR-15 build from a stripped lower or upgrading your current duty rifle, we provide the mission-critical components required for 100% reliability. Our inventory of AR15 parts covers every sub-system of the modern sporting rifle—from match-grade 416R stainless barrels and MPI-tested bolt carrier groups (BCG) to crisp, drop-in triggers and ergonomic M-LOK handguards. Every component is vetted for mil-spec compatibility and precision tolerances, ensuring that your build maintains peak performance under the most demanding conditions.
In the rapidly evolving world of the AR platform, we specialize in parts that support the latest ballistic innovations, including suppressor-ready gas systems, adjustable gas blocks, and caliber-specific components for 300 Blackout, 6.5 Grendel, and 6mm ARC. We understand that a rifle is only as good as its weakest link, which is why we stock only top-tier AR-15 accessories and internals made from high-strength materials like 7075-T6 aluminum and chrome-moly vanadium steel. From small spring and pin kits to complete furniture sets, find the high-quality AR15 components you need to enhance your rifle’s accuracy, reduce felt recoil, and maximize your efficiency on the range or in the field.
