Frequently Asked Questions

Do I need an FFL to buy AR-15 parts and accessories online?

Most AR-15 parts, such as triggers, grips, stocks, handguards, and other non-serialized components ship directly to your door with no Federal Firearms License required. Only serialized lower receivers and complete rifles must transfer through an FFL.

What is your return policy on AR-15 parts?

Uninstalled parts may be returned within 30 days for a refund or exchange. Return shipping costs may be deducted from your refund depending on the reason for return. See our Returns page for details.
