Hello, I'm very interested in building an AR. I have limited experience with these guns but every time I have shot one i have had an absolute blast. I have a few questions regarding the AR: Some of the rifles i have shot felt rather cheap as I could hear the spring after every shot and it gave off a very cheap impression. Are there ways to work around this? What brands should I stay away from? What brands would you reccomend looking into? Any helpful tips or information are greatly appreciated.
