Everything 10X said is DEAD ON !!!! I don’t know why but the rifles ive rebuilt almost always have a light twang …It can be quietened up some but the best way is to grease main spring heavily , and then it causes big jumps in velocity. On my personal gun my first piston buffer wouldn’t stay properly seated and would be canted slightly and when it happened you could see it in groups fast as there became more vertical stringing .
