The KAK Industry AR-15 Basic Ambi Lower Parts Kit Build Kit (KAK part number AR15-LP-KT-03) covers the internal components an AR-15 lower needs to function, built around an ambidextrous configuration for shooters who want left- and right-hand controls without sourcing them separately. KAK built this kit around a simple philosophy: everything you need for your custom build, and nothing you don’t. That means a straightforward, no-frills parts kit rather than an upsold bundle, making it a practical choice for a first build or a spare-parts backup for an existing rifle. It’s a Title I firearm accessory kit, containing no receiver and no regulated components.
