Thanks again. I just read
this thread, which is I believe the one you're referring to. Great writeup.

So I understand correctly, the information I listed above is accurate; 6.03mm, a very good hop-up rubber, and a well-sealed gearbox is the key to accuracy and range. However, should I be upgrading the internals and/or the spring?
As well, do you have any suggestions on what brand of parts I should get? As well, if I understand correctly, the Flat Hop is the better bet for heavier ammunition. Where do I get such a thing?
I see one on AirsoftDepot.ca, but is out of stock, and I don't know about many other recommended sites. Thanks in advance.
