How Our Online Rifle Builder Works
BuildARifle is a free online rifle builder and AR-15 configurator — here's what that actually means and how to get the most out of it.
Pick a Starting Point
Every build starts one of two ways: choose a complete rifle from our catalog, or pick a matched upper and lower combo and build out from there. Either way, you land in the same visual rifle builder — just with a different base to work from.
What You Can Add to Your Build
Optics, mounts, suppressors, muzzle devices, grips, stocks, lights, magazines, and other accessories — every category renders directly on your rifle as you add it, so you see the real, scaled result before you buy anything.
Real Components, Real Pricing
Every part in the builder is a real, recognizable product. Once your build is finished, we show live pricing from Palmetto State Armory and other trusted retailers so you can compare and buy directly from a trusted retailer.
Compatibility Built In
Our optics system pairs scopes with the correct mounts, and our suppressor system matches adapters to the muzzle device you've selected — so incompatible combinations aren't offered in the first place.
Save and Share Your Build
Finish a build and you get a private link to keep editing it, plus a shareable summary link for anyone else. No account required. You can also submit your build to be featured as Build of the Week.

Frequently Asked Questions
What is an online rifle builder?▾
An online rifle builder is a tool that lets you visually assemble a rifle from real parts — optics, suppressors, grips, stocks, and more — in your browser, so you can see and price out a complete build before buying anything.
Is the BuildARifle rifle builder free?▾
Yes. BuildARifle is completely free to use, with no account required to build, save, or share a configuration.
Can I build an AR-15 online?▾
Yes. BuildARifle currently focuses on the AR-15 platform — choose a complete rifle or an upper/lower combo, then add optics, suppressors, and other accessories visually.
Does BuildARifle check part compatibility?▾
Yes, for the systems we currently support: our optics system only pairs scopes with compatible mounts, and our suppressor system only offers adapters that match your selected muzzle device's standard.
Can I save and share my rifle build?▾
Yes. Every build gets a private edit link and a separate shareable summary link, so you can keep working on a build or send it to someone else without an account.
Does BuildARifle sell firearms?▾
No. BuildARifle is a configuration and price-comparison tool, not a licensed firearms dealer. Purchases happen directly through our retail partners, including Palmetto State Armory and other trusted retailers.
Can I compare prices from different retailers?▾
Yes. Once you finish a build, BuildARifle shows live pricing across our retail partners so you can see the lowest price for each part, or shop by a single merchant.
