Hey everyone! Tried finding a solid answer and I can’t seem to looking around. If it’s on here and I missed it, I’m sorry. Also if this is in the wrong spot to ask, I’m also sorry (I’m new here). So I bought a few Accuracy International AT rifles with a folding stock in 6.5 Creedmoor. Love them by the way, but sadly this is the second one I’m having issues with. Today when I brought my newest one out, I went to loosen the cheek riser screw on the one side, and the whole screw and threaded insert just fell right out. Being I already sent one back with a defect and is currently there, I don’t want to send this back. Is it difficult to install a new rear chassis to the folding adapter? I’d rather install a new chassis piece myself if they are willing to send it. Here’s what I’m working with. Again, If this is already out there, I’m sorry. I just can’t locate it. Help lol
