New
- • Build a kit: spec a full AR build from parts across retailers, save it, and share the link with a buddy or a forum. More build features on the way.
- • Welcome to the new ARPartsFinder. After months of development and a complete front-end and back-end redesign, we are happy to go live. A lot of testing and great feedback from our beta testers got us here. Same mission since 2013, finding AR-15 and AR-10 parts in stock across retailers, now faster and a lot easier to use.

New
- • Revisited and refreshed our Bravo Company USA scan for their current site. A Hartland, Wisconsin based manufacturer known for mil-spec AR-15 uppers, barrels, bolt carrier groups, and the BCM Gunfighter charging handle. Now scanning a wide range across complete uppers, barrels, BCGs, charging handles, handguards, muzzle devices, triggers, grips, sights, and magazines.

New
- • Added Fulton Armory to our scans, a Maryland based manufacturer-direct maker of complete AR-15 (FAR-15) and AR-10 (FAR-308 Titan) uppers, lowers, barrels, and handguards.
- • Revisited and refreshed our New Frontier Armory scan for their current site. A Las Vegas based retailer and maker known for its polymer and billet AR lower receivers, also carrying brands like DPMS, KAK, and Magpul. Currently scanning complete uppers and stripped lowers.
Improved
- • The Newest, Popular, Sales, and Recently Out of Stock lists can now be filtered by retailer, price, and search, the same way Browse already could.
- • Removed listings from a few retailers that have gone out of business, part of the ongoing site relaunch.
- • Added a guns.com AR-15 build guide (10 steps, with videos) to the Resources page build guides.

2026-06-02
New
- • Added Classic Firearms to our scans, a large North Carolina based retailer carrying dozens of brands at competitive pricing. Categories now searchable: complete uppers, stripped uppers, complete lowers, stripped lowers, and AR magazines.
- • Added Magpul to our scans, the manufacturer-direct accessory maker known for the iconic PMAG magazines, the MOE/CTR/SL stock lines, MBUS sights, and M-LOK handguards. Categories now searchable: grips, handguards, magazines, back-up iron sights, and stocks.
Improved
- • Browse cards: thumbnail preview now opens on click, not hover. The hover trigger was firing as you scrolled past cards and the popup kept covering parts of the page, which got annoying. Table view still uses hover (thumbnails sit in their own narrow column on the left, well out of the scroll path).
Fixed
- • Cleaned up dead and moved links on the AR-15 Resources page (MidwayUSA build guide, AR15.com lower assembly guide, GunBroker FFL finder, and ATF FFL eZ Check).

New
- • Added CMMG to our scans, a manufacturer-direct AR maker known for the BANSHEE pistol-caliber carbines, RESOLUTE rifle line, DISSENT lower receivers, and ZEROED suppressor-integrated platforms. Around 260 more in-stock parts to search and build with: complete uppers and lowers, stripped receivers, BCGs, charging handles, lower parts kits, magazines, stocks, and a small selection of armorer tools and cleaning supplies.

Improved
- • The sign-in 'Check your email' page now reminds you to check your spam folder if the email doesn't show up after a minute or two.
- • Sharing ARPartsFinder URLs on Discord, Reddit, X, and similar apps now shows clean preview cards instead of just a raw URL. Build URLs preview with the build's name and a quick summary (like '3-part AR build: Mags, Complete Lowers, Complete Uppers. Total $425.'); other pages show their specific title and description.
- • You might notice build URLs in your address bar now include a slug from the build's name (e.g., /b/abc123/my-first-7-5-inch-build instead of just /b/abc123). The bare form still works; it redirects to the slugged version, so existing bookmarks and Share-button links are unchanged. If you copy from the address bar, the slugged URL goes with it.
May 30, 2026
New
- • Added Weapon Outfitters back to our scans. They were dropped years ago when their site changed platforms. An independent retailer with curated AR-15 parts from brands like Sons of Liberty Gun Works, Radian Weapons, and LMT. Currently scanning charging handles, handguards, and pistol grips, with more categories coming soon.
May 29, 2026
New
- • You can now also ⊘ hide specific retailers from your default browse view. Open the Retailers menu and click the ⊘ next to any retailer to hide it; a 'Clear hidden' link in the footer un-hides them. Useful for trimming back a manufacturer-direct catalog that's dominating a category so you can compare what other retailers carry. Works alongside the preferred-retailers feature, so you can both prefer some retailers AND hide others.
- • Added Bear Creek Arsenal to our scans, a manufacturer-direct AR maker known for their BC-15 barrel line and a broad AR-15 catalog: complete uppers and lowers, barrels, BCGs, magazines, handguards, muzzle devices, gas blocks and gas tubes, and stripped uppers. Around 640 more in-stock parts to search and build with.
- • You can now save your preferred retailers, and future Browse pages auto-filter to them. Open the Retailers menu, check your favorites, and click 'Save as preferred'. A 'show all' link in the result bar widens to every retailer for the session whenever you want to compare. Your picks are saved in your browser.
- • Added Redacted Arms to our scans, a specialty maker of the Super Safety and Active Reset Trigger fire-control modifications for AR-15 builds.
- • Added Ballistic Advantage to our scans, a manufacturer-direct maker focused on premium AR-15 and AR-10 barrels (across a wide range of calibers) plus uppers, BCGs, muzzle devices, and gas system parts.
- • Added WMD Guns to our scans, a manufacturer-direct maker known for nickel-boron (NiB-X) bolt carrier groups, barrels, and uppers.
- • Added MidwayUSA to our scans, bringing in around 2,000 more in-stock AR parts to search and build with, including uppers, barrels, handguards, bolt carrier groups, triggers, magazines, and optics.
Improved
- • Browse pages now sort by price (high to low) by default, so a category leads with its complete and premium parts. You can still sort by newest, oldest, or price low to high from the Sort menu.
May 28, 2026
Improved
- • Renamed 'draft build' to 'working build' across the site, so the kit you're assembling in your browser has one consistent name.
- • Refreshed the home page with a clearer description of what the site does and a callout for the build feature.
- • Reorganized and expanded the FAQ: clearer working-vs-saved builds, a quick comparison of what an account adds, why saved builds keep permanent links, what the compatibility warning means, and a bit of site history (we've been tracking AR parts since 2013).
May 27, 2026
New
- • Build pages now flag likely compatibility issues. If you mix parts that won't work together (a .308 mag with a 5.56 upper, a 9mm lower with an AR-15 upper, a 6mm ARC upper with 5.56 mags), you'll see a soft warning before you click through to a retailer.
- • This page. A running log of what's recently changed on the site.
Improved
- • What's new entries are now grouped by type within each day so the page reads more cleanly.
- • Continuing a saved build now shows clearer guidance on how to add more parts to it.
- • Editing a saved build with no free draft slots now shows a chooser asking which slot to replace, instead of silently overwriting your active draft.
- • Drafts that are editing a saved build are clearly labeled '(editing)' so they don't look like a second copy of the saved version.
- • Saving or updating a build now frees the working draft slot. The saved version lives in My Builds; the slot is ready for new work.
- • Drafts now appear on the My Builds page, above your saved builds, so you can resume any in-progress build from one place.
Fixed
- • Report-wrong-category form now works properly inside dialogs on iOS.
- • Renaming a saved build on a small phone screen no longer squeezes the input box.
- • Image previews on mobile now reliably close with a tap.
May 26, 2026
New
- • New pages: FAQ, AR-15 Resources, and Terms & Privacy.
- • Saved builds now have a version history, so you can see what changed each time you update one.
- • Tap-to-copy buttons next to every shareable build URL on /build and /my-builds.
- • Mobile redesign with a bottom navigation bar, slim header, and a More menu.
Improved
- • Browse cards on mobile: cleaner price-plus-sparkline layout.
- • Saved-build summary now shows an 'Available now' subtotal when some items are out of stock.
ARPartsFinder has tracked AR parts since February 25, 2013.
Here is what it looked like a week in.
