This tungsten alloy buffer weight for AR15 buffer system is manufactured by inculcating the best quality tungsten alloy and pioneering technology under the vigilance of our adept proficient The buffer is one of many pieces that helps your rifle to operate normally. When a bullet has fired, the energy that it released pushes the bolt carrier backwards which then connects with the buffer within the buffer spring and tube. At the point of contact, the buffer pushes the spring backwards. Depending on the weight of the buffer and the strength of the spring, the buffer will reconnect with the bolt carrier pushing a new bullet forward into the chamber to be fired. Why is the buffer weight so critical? If you get a weight that is too heavy, the rifle won’t be able to push the spring back and reload the weapon. If you get a buffer that is too light, then the bolt carrier might move too fast and not perform the correct functions.
