Just and Update. I could t find any of the Armalite buffer tube kits. So Inordered and Aero enhances kit along with a Tubbs flat spring. After everything installed it’s like a complete different rifle when feeding. The Tubbs spring is really smooth and quiet. All my mags load easily now. My Bolt catch also works now. I could t believe the issues that the m4 spring and buffer caused. Thanks for all the help guys
