The AR-15 Buffer System and why it's important

Posted by PMA Staff on Jun 28th 2023

The AR15 buffer system is an essential component of the AR15 rifle, which is widely used in military, law enforcement, and civilian applications. The buffer system plays a critical role in ensuring the reliable function of the firearm, as well as providing the shooter with a comfortable shooting experience.

The AR15 buffer system consists of several parts, including the buffer tube, buffer spring, and buffer weight. These components work together to control the movement of the bolt carrier group during firing, which helps to ensure proper feeding, extraction, and ejection of the spent cartridge.

One of the primary functions of the buffer system is to absorb recoil energy and prevent excessive movement of the bolt carrier group. The buffer weight, which is located inside the buffer tube, is designed to provide a counterbalance to the recoil energy generated by firing the rifle. This helps to prevent the bolt carrier group from moving too quickly and slamming into the back of the receiver, which can cause damage to the firearm and increase felt recoil.

In addition to controlling recoil, the AR15 buffer system also plays an important role in regulating the cyclic rate of the firearm. The cyclic rate refers to the number of rounds that can be fired in a given period of time. A properly tuned buffer system can help to ensure that the cyclic rate is consistent and within safe limits, which can help to prevent malfunctions and increase accuracy.

Another important benefit of the AR15 buffer system is that it helps to reduce felt recoil for the shooter. By absorbing and dissipating recoil energy, the buffer system can help to make the rifle more comfortable to shoot, which can lead to improved accuracy and faster follow-up shots.

Overall, the AR15 buffer system is a critical component of the firearm that plays a vital role in ensuring reliable function and a comfortable shooting experience. Shooters should take care to select the appropriate buffer weight and spring for their specific application, and should periodically inspect and maintain their buffer system to ensure that it is functioning properly. With proper care and attention, the AR15 buffer system can provide many years of reliable service and enjoyment for shooters of all skill levels.
