Frequently Asked Questions

Where can I find the best gun parts deals online?

Palmetto State Armory leads in value-tier AR parts. Aero Precision offers excellent quality for stripped lowers and M4E1 uppers. Brownells has the widest aftermarket catalog. We track all of them hourly.

What are the best gun parts brands right now?

For AR-15 builds in 2026: Aero Precision (lowers/uppers), Ballistic Advantage (barrels), BCM (complete uppers), Geissele (triggers), Toolcraft (BCGs), and Magpul (furniture) offer the best value-to-quality ratios.

Do I need an FFL for gun parts?

Only for serialized components. The stripped lower receiver is the legally-defined "firearm" and requires FFL transfer. All other components — uppers, barrels, BCGs, triggers, handguards — ship directly to your door in most states without an FFL.

How often are gun parts prices updated?

Our scraper fleet re-scans every retailer hourly. Flash sales on AR parts — especially stripped lowers — can sell out within hours. Our hourly refresh rate means you see deals before they sell out.

Where can I find cheap AR-15 lowers?

Palmetto State Armory, Aero Precision, and Anderson Manufacturing offer the best value stripped lowers. PSA and Anderson lowers regularly drop to $39-69 during sales. Our AI flags these price drops automatically.
