this is a great upgrade for any cocker, it looks cool, lowers the operating pressure, increases shot to shot consistency, and slightly increases accuracy. the bad part about the lpc is that it can kinda clutter the pneumatic area abit. I had to go the my paintball supply store to by new hoses because my original didn't reach all of the way around the chamber. i heard that it made the gun quieter but it was negligible. the instaltion was pretty simple(make sure you have enough hosing and some teflon tape) If you don't know what you are doing than i would study up on how to take apart your cocker or have a shop do it.
This is a very inexpensive upgrade for your cocker, and it makes your gun look unique. it doesn't really quiet the gun down that much though. I would say that this is an excellent part to buy for your autococker.
