The lower part of an AR-15 is essentially what is considered "the firearm" as it contains the trigger assembly. The lower is also perhaps the most inexpensive part of the firearm and arguably least important.
For this build we considered our options and narrowed it down to a PSA lower kit that we found online. However, due to a number of factors including item availability, shipping to an FFL (fees), delivery time and ultimately price we determined that we were better off purchasing a Spikes Tactical Lower from the local gun shop.
We have absolutely no regrets on this decision! This lower is exactly what we wanted for this build!
