I have been thinking about upgrading to non-rotating pins in my AR. I have had my AR for about 7 years. I don't shoot it a lot, because I can't afford it, but I would guess I have put 2000-2500 rounds through it. If I upgrade the pins, do I need the .154 or the .155 oversized pins? I am unsure if I have fired it enough to have warn it to the point of needing the oversized pins. Any help would be great.
Thanks!
