Easy Build Experience 

If you’re short on time, patience, or experience, AR lower build kits are an accessible way to build an AR-15 from scratch. With so many pieces to consider in a build, you don’t want to lose track of any of your smallest and most crucial components. When you shop Durkin Tactical, you can rest assured that each kit we carry delivers every piece you’ll need.

Sweat the Small Stuff 

With so many cool customizations available, lower parts can sometimes get overlooked. But these little parts are incredibly important — they have a huge impact on your gun’s longevity and shooting performance. In a lower parts kit you’ll find a hammer, magazine catch, safety, grip, trigger, and buffer assembly, all 100% compatible and ready to build out.

Guaranteed Compatibility for Total Peace of Mind

Buying each of your lower parts individually makes for a more complicated experience, and runs the risk of incompatibility. When you opt for a Durkin Tactical lower parts kit for your next build, you’re choosing a carefully curated selection of parts for guaranteed compatibility. Stop worrying about compatibility, and focus on customizing your build with accessories and upper parts.
