As the point of contact for the Bolt Carrier Group (BCG), the buffer system is an absolutely vital part of your firearm. Most AR's come "overgassed" from the factory to ensure reliability. The parts in this category will allow you to fine tune the system to operate just the way you like it. Just remember that there is a bit more to recoil and gas management than just the buffer system. Take some time to look at the other great products we have for you elsewhere on the site!
