What is an AR-15 lower parts kit?

The AR-15 lower parts kit are the parts that are installed in the lower receiver of an AR-15. This includes parts such as the grip, trigger, magazine catch, and all the necessary parts to turn your lower receiver into a functional rifle. Many of our lower parts kits come with varying parts so make sure to read the product description prior to ordering to make sure you receive the exact product you need.

I ordered a lower parts kit. How do I install it?

What's the difference in lower parts kits?

You've seen different types of lower parts kits such as drop-in, enhanced, and regular. Each lower parts kit serves its own purpose and you can find out more information on each products page. In general, though, the drop-in contains most of the lower parts minus the trigger. This is for those that anticipate upgrading certain components of their lower. The enhanced lower parts kit includes all the necessary components including the trigger and will usually have upgraded parts such as a better grip, better trigger, etc. The standard lower parts kits are usually the entry level kits that are good for first time builders. The kits include all the normal parts including the trigger.
