2. Choose Use Case

This shifts budget allocation toward parts that matter most for your intended use.

Smart Allocation

Budget is distributed across 14 categories based on how much each part typically costs relative to a complete build. Barrel and handguard get the largest shares.

Real Prices

Every recommendation is backed by a real product listing from one of our partner retailers. Prices update regularly so what you see is what you pay.

Compatibility Checked

The recommended build runs through the same compatibility engine used in our full builder. Platform, caliber, and gas system mismatches are flagged automatically.
