M5 .308 Standard Lower Parts Kit by Aero Precision

If you plan to start an LR-308 build, you're gonna need a good lower parts kit. Aero Precision makes a lower parts kit designed for their M5, which is their own proprietarily designed .308 rifle that can also work with your LR-308 build, provided yours is based on the regular DPMS gen 1 pattern. This lower parts kit contains all the necessary parts to complete your lower receiver. See below for more info.

Need help? Here's how to install your lower parts kit!

NOTE: While this lower parts kit will work with your DPMS gen 1-patterned .308 lower, it was specifically designed for the M5 by Aero Precision. This means that while it will still work, the pivot and takedown pins will protrude farther from the lower than those of a standard lower parts kit.
