AR15 Lower Build Kits & Parts Kits

AR15 Lower Build Kits and Parts Kits are essential components for enthusiasts and builders who wish to assemble or customize their rifles.

These kits are designed to provide the necessary parts for the lower receiver of the AR15, which is the portion of the firearm that includes the firing mechanism, magazine well, and buttstock attachment point, among other critical functions.

AR15 Lower Build Kits

AR15 Lower Build Kits typically encompass all the parts needed to fully assemble the lower receiver.

These kits often include the trigger assembly, hammer, safety selector, magazine release, bolt catch, and all necessary pins and springs. Depending on the specific kit, AR Lower Build Kits may also include a pistol grip and buttstock.

These kits are designed for both novice and experienced builders and offer a comprehensive set of components that ensure compatibility and ease of assembly.

AR15 Parts Kits

AR15 Parts Kits, while similar to Build Kits, can vary in the range of components they include.

Some AR Parts Kits may offer a more focused selection of components, such as just the parts for the trigger assembly or a specific set of springs and detents.

These kits are ideal for shooters looking to upgrade or replace specific parts of their lower receiver rather than assembling a new one from scratch.
