What is the state of your AR-15's lower receiver? Dedicated rifle owners, especially those with professional or competitive ambitions, should always have a good understanding of it. After all, firearms do not stay in perfect shape on their own for all time. Parts lose their robustness over time and wear down with use, bringing down the entire rifle's performance with them. If you want to get the most out of your gun, regular maintenance is crucial.


Sometimes, that maintenance requires replacing AR-15 lower assembly parts that no longer cut the mustard. However, you are not required to simply get a newer example of the same model. Many professionals take the opportunity to shop for different models of a higher quality. Even one savvy swap can boost the capabilities and performance of the entire rifle. Shopping smartly requires greater thought and effort, but the results can seriously pay off.


If you like the idea of upgrading your receiver, you have come to the right place. Gorilla Machining is thrilled to provide a variety of AR-15 lower assembly parts, all designed by our in-house experts in line with high standards of quality. We would not sell anything that we would not use for our own rifles.
