Take the advise offer and stone off rough areas. A new piston, any piston, may reduce the accuracy of the rifle, the odds of it improving the accuracy are not in your favor after all the time you have had the piston in question, I assumed you fired many rounds . Art..Cleaned the gas system prior to match. Gas piston is original 1988. Noticed rough edges at front and rear of piston. Should I replace piston? Any preference as a replacement. Old piston is grooved (six in front of hole and one in rear after the hole)
That is tough question, to my knowledge there is no hard evidence to support any position when it comes to pistons and gas cylinders. As to your question, it takes many rounds to wear out a Gas cylinder or a piston, particularly, if little rapid fire has been done.So Art, Do you recommend replacing the entire gas system when you feel it may be going? I have been wondering about this myself.
I am interested...does that count ?DI2That is tough question, to my knowledge there is no hard evidence to support any position when it comes to pistons and gas cylinders.
There is a method to use that is practical to a point, I'll get around to that if you are interested. Art
Thank you, I am also interested also in Piston/Cly relationship. Without the support of more than I can expect, I think the subject will stay where it is.Art, I'm interested, too, if you have the opportunity. I've read Gus' writings on trying to find a direct correlation between gas piston size and accuracy, and am generally happy with my accuracy, but am always looking to learn more.
