About AR15 Outfitters

What We Do

AR15 Outfitters is a free parts picker and compatibility checker for AR-15 builders. Think of it like PCPartPicker, but for rifles. Select parts across categories (lower receiver, upper receiver, barrel, BCG, handguard, and more), get real-time compatibility validation, and compare prices from multiple retailers, all in one place.

Why We Built This

Building an AR-15 should be straightforward, but the parts ecosystem is complex. Will this handguard fit that barrel nut? Does this BCG work with that caliber? Is this upper compatible with that lower? These are questions every builder faces, and getting them wrong means wasted money and time.

We built AR15 Outfitters to solve that problem: a single tool that validates compatibility as you build, shows you pricing across retailers, and lets you save and share your build list.

What We Are Not

We are not a firearms dealer. We do not sell firearms, parts, ammunition, or any regulated items. AR15 Outfitters is an informational and affiliate site. When you click a product link, you are taken to a licensed third-party retailer to complete your purchase. All transactions, shipping, returns, and compliance are handled by those retailers.

Accuracy

We work hard to keep our parts database, compatibility rules, and pricing data accurate and up to date. That said, manufacturers change specs, retailers adjust prices, and new parts enter the market constantly. Our compatibility checker is a reference tool, not a guarantee. Always verify critical compatibility with the manufacturer or a qualified gunsmith.
