When it comes to building your own firearm, the AR-15 pistol kit offers one of the most efficient, versatile, and rewarding experiences out there. Whether you're new to the platform or a seasoned enthusiast looking to create a compact powerhouse, AR15-Overstock.com has everything you need to get started — without the guesswork.

What is an AR-15 Pistol Kit?

An AR-15 pistol kit includes nearly everything required to complete your build — upper assembly, lower parts kit, buffer system, handguard, barrel, and more. The only thing you'll need to supply is the stripped lower receiver, which must be purchased through an FFL.

The result? A short-barreled, highly maneuverable firearm that’s perfect for range shooting, vehicle storage, or home defense — all in a legally classified “pistol” platform.

Why Build an AR-15 Pistol?

There are a few big reasons builders choose AR-15 pistols:

• Compact Design – Ideal for close quarters, tight storage, or travel setups.

• Legal Flexibility – Depending on state and federal regulations, AR pistols often bypass the NFA restrictions tied to SBRs (Short Barrel Rifles).

• Customization – Choose your caliber (.223/5.56, .300 BLK, 9mm), colors (like black, FDE, red, and blue), and barrel lengths (7.5”, 10.5”, etc.) to match your goals.

• Affordability – Buying a complete kit saves money compared to purchasing parts individually.
