So i bought my ACR used a year ago. It's a low model serial number in the 3000's. When I first got the rifle I noticed that the charging handle was abnormally loose and wobbly. However this did not seem to effect the rifles performance. Not until the last month when I noticed that my charging handle started to reciprocating with the bolt carrier. I noticed that the tab on above the bolt carrier is free floating and the holes where I assume it meets with the carrier is completely seared! Wondering what my best options are? Order a next Actuator Assembly and install it myself or send it off to Bushmaster and have them fix it, likely out of warranty unless they deem it a factory defect. Attached are some pictures. I'd greatly appreciate any feedback!
