One of the most frequently asked questions in AR-15 groups or boards is, “What AR-15 buffers should I consider for my build?” The answer is not always as simple as someone would like, as several factors will determine the proper buffer. Complicating the process is the fact that many who are new to the AR platform don’t quite grasp what the buffer system does or how it works.
While factors like craftsmanship, quality, and the like are critical, most people seem to neglect the reasoning behind their build choices. When building an AR-15, there are many variables to consider, and your choices must be informed by the results you tend to achieve. Once you start to focus on the “why” during your decision making process, a much clearer and informed picture will present itself.
