AR15Parts.com’s digital storefront and upcoming mobile app feature a state-of-the-art 3D configurator that enables Denison, TX customers to visualize their AR-platform builds in real time. Users select an upper receiver style, choose barrel length and profile, pick handguard interface (M-LOK, KeyMod, or Picatinny), and add bolt carrier group and charging handle options, watching their virtual rifle assemble before their eyes. Compatibility alerts prompt users if mismatched gas-system lengths or incompatible muzzle devices are selected, while dynamic pricing updates reflect bundle discounts and shipping thresholds. Saved configurations can be shared via URL or QR code, enabling seamless collaboration with range buddies or gunsmiths. The app integrates barcode scanning to check on-hand inventory for local partners, and push notifications alert users when preferred components are back in stock. A built-in parts glossary links each component to detailed spec sheets, torque charts, and video tutorials, reducing guesswork and minimizing build errors. When ready, users can checkout directly within the app, choosing FFL transfer at checkout and selecting their preferred dealer. All orders over $99 receive free UPS Ground shipping, while NEXT BUSINESS DAY fulfillment applies to stocked items. AR15Parts.com’s mobile configurator empowers Denison, TX builders to create, refine, and order custom ar15 uppers and parts from the palm of their hand.
