Having an issue with a build i put together. I will admit I’m a novice when it comes to detailed knowledge beyond what you can pick up watching youtube videos. The build itself went fine. Put together a PSA lower parts kit on an Anderson lower and used a completed PSA upper with an 18 inch barrel.
The problem I have is the bolt catch will sometimes release with even the slightest of movement and the bold will go home. What could be the cause for this? Any suggestions would be helpful.
