Build Your Own American-Made AR Pistol with AR15-Overstock Pistol Kits

There’s something uniquely satisfying about building your own firearm. An AR15-Overstock pistol kit gives shooters a cost-effective way to craft a personalized, high-performance AR pistol while supporting American manufacturing. Whether you’re a first-time builder or a veteran shooter, our kits put control, quality, and customization in your hands.

Why Choose an AR15-Overstock Pistol Kit?

Choosing a kit over a factory-built pistol gives you control, savings, and a hands-on experience. Our pistol kits include matched parts and quality components so you can assemble a firearm that meets your exact needs.

Cost-Effective Custom Builds

Buying a kit typically costs significantly less than a pre-assembled pistol. You get premium parts without paying for factory labor or bundled features you don’t want.

Full Customization

From barrel length to handguard style and finishes, kits let you choose each component. Want a compact 5" micro build or a 10.5" .300 BLK setup? Pick the kit that fits your mission.

What’s Included & What to Expect

Kit contents vary by SKU, but most pistol kits include the core parts needed to assemble your AR pistol.

Typical Kit Contents

  • Pistol upper assembly (barrel, gas system, handguard)

  • Bolt Carrier Group (BCG) & charging handle (included on many kits)

  • Lower parts kit (LPK) — trigger, pins, springs

  • Pistol buffer tube or brace-ready tube (when listed)
    Note: Stripped lower receivers are usually not included and must be purchased through an FFL.

Build Tips & Best Practices

Assembling your pistol is straightforward with the right tools and approach.

Prep & Tools

Work on a clean bench and gather basic armorer tools: vise block, punches, torque wrench, and armorer’s wrench.

Gas System & Reliability

Short-barrel pistols need properly matched gas systems. Choosing a kit with a specified pistol or micro gas length reduces tuning headaches.

Inspection & Safety

Function-cycle the firearm (no ammo) to check operation before live fire. If you’re unsure about headspace or final safety checks, consult a qualified gunsmith. Need guidance? 

Legal & Compliance Reminder

Firearm laws vary by state and can change. Before purchasing or assembling a pistol, confirm federal and state rules about braces, barrel length, and NFA items like SBRs and suppressors. For official federal guidance, consult the ATF (opens in new tab): ATF — Firearms Rules & Regulations.

Frequently Asked Questions
