ok i was just wondering why those classic rifles does that sound but newer ar15 like the stagarms model 1 i ve shot doesnt.. another recoil system?
Forget the grease. Buy a new quality rifle spring for your gun. (Wolff Gunsprings) I think the present spring has had better days and needs replacing. The spring presently installed must be some 20+ years old.
I found when these long, large springs weaken excessively, they start to rattle.
