These are the tools that already work today—built for folks who wrench on rifles, hunt, compete, or just enjoy tinkering.

Builder

Keeps you on track

  • Shows what’s required vs optional with a clear progress meter.
  • Understands bundles and DIY skips so weight, length, and cost stay honest.
  • Add parts from the catalog, clear it, or start over anytime.
Saved builds

Share and get feedback

  • Save builds to your account, edit later, or copy a build you like.
  • One-click share for Reddit, Markdown, plain text, or just a link.
  • Public pages allow voting, comments, and reporting to keep things clean.
Catalog

Parts you can sort and filter

  • Essential vs accessory pages with search and pagination per category.
  • Sort by name, price, maker, or rating; filter by price, bundles, and more.
  • Caliber, material, and barrel-length filters where they make sense.
Product Pages

Price history up front

  • Merchant offers, lowest-price callouts, bundle contents, and spec breakdowns.
  • Price history sits next to ratings and reviews so you know if it’s a fair deal.
  • Add any part to your build; saved builds update on the server when you’re signed in.
Discovery

Public builds you can copy

  • Browse community builds with filters for name, user, price, rating, and weight.
  • Sort by newest, oldest, high/low price, rating, or weight.
  • Open any build to see components, totals, and what was skipped.
Marketplace Coming soon

Community listings

  • Browse and search listings by type, location, and price; sort by recency or price.
  • Listing pages include component breakdowns, condition badges, and contact/report actions.
  • Seller flows (create, multi-item bundles, gifts, delete) are being polished before launch.
