Find In-Stock AR Parts. Compare Prices. Build Your AR.
The live in-stock search engine for AR-15, AR-10, and every AR build. We show what's actually available across retailers right now, then you buy direct from whoever has it.
Build your AR, part by part
Add parts to a kit as you browse, watch the running total and price history update live, then save it to a shareable link you can post on a forum, share on socials, or send to a friend. A real kit builder, not just a parts list.
