AR-9

The AR-9 platform is a highly versatile and efficient choice for shooters who value the functionality of an AR-style rifle chambered in pistol calibers. At Arm or Ally, we offer a comprehensive range of AR-9 components designed to meet the needs of builders and shooters alike. Whether you’re building a competition-ready pistol-caliber carbine, upgrading a personal defense weapon, or customizing your rifle for training sessions, our collection has you covered. From lower and upper receivers to barrels, handguards, and small parts, we provide everything you need to create a high-performance AR-9 that excels in any scenario.

AR-9 lower receivers form the foundation of your build, and we offer stripped, complete, and receiver sets for your convenience. Stripped lowers from trusted brands like Aero Precision allow for complete customization, while complete lowers save you time with pre-assembled components. Additionally, receiver sets pair upper and lower receivers for a seamless fit and consistent aesthetic. Each option is crafted for reliability and precision, ensuring smooth operation and compatibility with Glock or Colt-style magazines. Choosing the right lower receiver is essential for the overall functionality of your AR-9, and we offer the perfect options for every builder.

Our selection of AR-9 upper receivers provides essential options for finishing your build. Whether you prefer slick-side uppers or those with enhanced features like last-round bolt hold-open, our inventory caters to various preferences. Aero Precision continues to lead the market with their precision-machined uppers, offering both stripped and complete options for builders looking to optimize performance and ease of assembly. Pair your upper receiver with a quality barrel to ensure consistent accuracy and reliability. At Arm or Ally, we offer a variety of upper receiver configurations, each designed to meet the needs of both novice and expert builders, ensuring your AR-9 performs at its peak.

AR-9 barrels are a critical component for any build, influencing factors like accuracy, velocity, and reliability. We offer barrels in various lengths and profiles to accommodate different shooting styles and applications. Shorter barrels are ideal for compact PCCs, while longer options provide increased velocity for precision shooting. Our selection includes trusted manufacturers like Faxon Firearms and Ballistic Advantage, both renowned for their innovation and exceptional craftsmanship. Whether you need a barrel for close-quarter combat or long-range precision, our selection ensures optimal performance and accuracy to meet your needs in any shooting scenario.

Enhance your rifle’s ergonomics and accessory compatibility with AR-9 handguards. Our selection includes lightweight M-LOK and KeyMod systems that provide flexibility for mounting optics, lights, grips, and other accessories. Leading brands like Magpul and Breek Arms offer durable and stylish options to suit any build. These handguards not only improve handling but also protect your hands from barrel heat during extended shooting sessions. With ergonomic designs that prioritize comfort, our handguards are the perfect addition to your AR-9, ensuring a balance of form and function for any application.

To fine-tune your build, we offer a variety of AR-9 lower and upper parts. Key components like triggers, magazines, buffer kits, and bolt carrier groups are essential for ensuring smooth cycling and reliable performance. Our selection features innovative triggers from Rise Armament and HIPERFIRE, while buffer kits and bolt carrier groups from Aero Precision and SB Tactical deliver consistency and dependability. Every part is chosen to enhance functionality and improve your overall shooting experience. Whether you’re upgrading or building a new rifle, these parts are designed to meet the needs of shooters demanding high performance and reliability.
