Build smarter. Shop better. Track what you own.
AR15.Build has grown beyond a simple builder. Plan across AR-15, AR-10, AR-9, AK, and Glock-compatible platforms, compare live product data, ask the AI assistant, and keep your parts, builds, and range history organized in one place.
New on AR15.Build
The site has outgrown the old “just a build tool” version
Recent releases added new entry points for research, ownership tracking, and local discovery.
AI assistant for builds, shopping, and compatibility questions
Ask for help picking parts, get a recommendation before you dig through listings, or talk through your current build. The assistant knows the catalog and your builds.
Parts Cabinet and Shooting Logbook
Track what you own, what is installed, what is still sitting on the shelf, and how many rounds each build has seen.
2A Places directory
Browse dealers, ranges, clubs, trainers, and other useful places by state and city from a single public directory.
Use It Your Way
AR15.Build now covers more of the full ownership cycle
Planning, shopping, saving, maintaining, and finding useful places or people all live here now.
Plan and compare
Move from rough idea to finished parts list with platform-aware builds, current product data, Popular Parts rankings, and planning tools.
Research before you buy
Read practical guides, browse brands and merchants, and use community builds to sanity-check choices before you spend money.
Track what you own
AR15.Build is no longer just for planning. Save builds, track owned parts, log range sessions, and stay on top of maintenance.
Buy, sell, and find places
Use the marketplace for parts, keep up with notifications, and browse local shops, ranges, clubs, and services in the directory.
