Are you tired of mushy safety selectors, sloppy takedown pins, and soft detents? Well, we have the answer for you!

Introducing, the Classified Defense Ultimate Lower Parts Kit. Over the last 10+ years we have had to change countless parts/components we didn't like and/or didn't trust. This lower parts kit very simply contains all of the best components that we have ever tested. Let our many years of hardship and experience in learning what works and what doesn't be your lesson. When you're life depends on the best parts you can get for a lower receiver, look no further!

No batch checking QC here. We inspect each and every single part that has the Classified Defense name on it!

With the use of Nitride on critical components, you are able to retain that crisp feeling along with decreasing wear.

Please Note: We created this option to allow customer to deselect the items that they already have and/or want to replace a standard component with something else. Don't forget to check out all the individual components we sell too!
