There are a few things to consider when assembling a lower parts kit for your AR-15 rifle. First, you’ll need to choose the right LPK for your specific needs. There are several different types of LPKs on the market, so it’s important to do your research and select the one that’s best suited for your build. Secondly, you’ll need to gather all the required tools and materials before beginning the assembly process. Once you have everything you need, assembly is relatively simple.
To start, ensure that your work area is clean and clutter-free. This will help prevent lost or misassembled parts during the process. Lay out all of the components from your LPK in front of you, and refer to your rifle’s assembly manual for guidance. Begin by attaching the trigger guard to the lower receiver. Next, insert the trigger assembly into the lower receiver and secure it in place. Then, install the magazine release button and catch.
After that, it’s time to install the safety selector switch. This is a critical component, so be sure to follow the instructions in your assembly manual carefully. Once the safety selector is in place, you can install the bolt catch and release. Finally, attach the pistol grip to the lower receiver.
With the basic components installed, your AR-15 lower receiver is now ready for final assembly. Depending on the specific parts kit you’re using, there may be a few additional steps required to complete the build. However, the above steps will give you a solid foundation on which to build your rifle.
