The Guntec USA AR-15 lower parts kit (brand part no. BUILD-KIT) supplies the small parts needed to complete an AR-15 lower receiver build, minus the pistol grip and trigger group, which shooters typically choose separately to match their build. Finished in black across mixed materials suited to each individual component, it’s a practical way to fill out a lower build without hunting down dozens of small parts individually. Made in the USA, it pairs well with any separately selected grip and trigger group of your choice.
