Geissele Automatics Ultra Duty Lower Parts Kit Black, Ambi Safety, Oversized Bolt Release/Catch for AR-15 05-435B

For AR builders who are looking to construct a top-of-the-line lower receiver, adding in a Geissele trigger group has always been a solid, go-to option. Now, the company produces all of the other internal parts needed for a fully functioning lower receiver, giving AR enthusiasts a one-stop shop to finish their rifle with high-grade components.

Each Geissele Super Duty Lower Parts Kit include proprietary components that are machined from stainless steel at the company's facility in North Wales, PA. The stainless-steel construction ensures that the internals of your AR-15 are less-susceptible to corrosion or failure throughout the lifetime of your rifle, even in extreme-use conditions.

In addition to many standard components, the Geissele Super Duty Lower Parts Kit also includes a few enhanced components, like the company's Maritime Bolt Catch, Ambidextrous Super Configurable and the company's Ultra Precision Trigger Guard. Each of these components are constructed with an eye toward improving the usability of the AR platform by allowing for more tactile engagement and easier access to critical control components.
