AR-15 Pistol Kits: Compact Power, Fully Customizable

Looking to build a compact, hard-hitting firearm without sacrificing performance? AR-15 pistol kits are the perfect way to create a lightweight, maneuverable AR platform with all the firepower you expect—minus the full rifle length.

At AR15-Overstock.com, our AR-15 pistol kits include everything you need to complete your build: upper assemblies, lower parts kits, pistol-length barrels, buffer systems, and more. Whether you're going for a range-ready blaster or a truck gun, our kits give you control over the specs without breaking the bank.

Why Go with an AR-15 Pistol Kit?

• Compact & Versatile – Shorter barrel and buffer tube setups mean better handling in tight spaces.

• Custom Builds – Choose your caliber, barrel length, handguard style, and finish.

• Easy Assembly – All parts in one place, ready to assemble on your lower receiver.

Whether you’re a first-time builder or a seasoned DIY shooter, our AR-15 pistol kits are built for reliability, performance, and maximum customization.
