New
- • Rainier Arms is now live on ARPartsFinder. We added their in-stock lineup (barrels, handguards, triggers, muzzle devices, BCGs and more) to search and price comparisons.
Improved
- • Grouped individual small parts (detents, springs, safety selectors, dust covers and more) into a clearer 'Small Parts' category, found under 'Other', so single components are easier to find.

Improved
- • We made several backend infrastructure upgrades this week, including a large database change that makes the whole system run more efficiently. Nothing changes in how you use the site day to day, but it keeps things fast and dependable as we grow, and it lays the groundwork for more speed improvements to come.

Fixed
- • Moving to another page of results no longer drops your filters. Page navigation now keeps every filter you have set.
June 19, 2026
Fixed
- • Cleaned up the product price chart: the timeline now labels whole dates instead of times of day, and the price axis reads to the cent.
June 17, 2026
New
- • Introducing product pages. Every part now has a 'Price history & details' link on its card that opens a page of its own: a price chart across the whole time we have tracked it, the lowest and highest prices we have seen, and a direct link to buy from the retailer.
June 16, 2026
Improved
- • Faster page loads. We slimmed down the styling code the site sends to your browser and switched on compression, so the home, browse, and build pages come up noticeably quicker, especially on phones and slower connections.
Fixed
- • On phones, the footer no longer repeats the menu links that already live in the bottom app bar.
- • Cleared a stray horizontal scrollbar that could appear on wider desktop windows.
June 13, 2026
New
- • Our sister sites now have a spot in the footer, a quick hop to our other in-stock finders when your search goes beyond AR parts.
Improved
- • Signed-in members can now rename their working builds, so a kit you are still putting together carries a name you recognize instead of a default.
June 10, 2026
New
- • San Tan Tactical joins the lineup, with live in-stock prices on their AR-15 receivers, barrels, bolt carrier groups, triggers, and handguards.
June 9, 2026
New
- • KAK Industry is now in our scans, with live stock and prices across their AR-15 and AR-10 parts: barrels, bolt carrier groups, upper and lower receivers, handguards, buffers, charging handles, gas blocks and tubes, and lower parts kits.
June 7, 2026
Improved
- • Shared build links now include the build-value-over-time chart (the same one you see while building), so anyone you send a kit to can see how its total price has trended.
- • Browse now starts with the most recently added and restocked parts instead of the most expensive ones, so you land on fresh stock first. More browse improvements are on the way to make finding specific parts even easier.
June 6, 2026
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.
June 5, 2026
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.
June 4, 2026
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.
June 2, 2026
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).
June 1, 2026
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.
May 31, 2026
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).
ARPartsFinder has tracked AR parts since February 25, 2013.
Here is what it looked like a week in.
