Thats something Il looked at when I bought it . looks like its never been fired. was told it was an attempt to replace the trigger and it didnt quite work out but he didnt bother to bring the parts with him. Tried a no-go gauge in it, wouldnt close so Iam ok with the headspace, just need a trigger but dont feel real easy with messing with it, I do just fine with rem. and winchesterbut this one I think Ill pass on. Thanks for asking though!
