ZCI barrel and maple hop fitted into the cyma ak fine with some minor gains.  267-273fps went up to 293-304fps.  Would have liked more, curious as to the increased bracket of fps too. 

Wonder what it means for my cylinder volume, would a shorter or longer barrel of the same narrowed diameter have provided better gains?  its gone from a 6.03 or 6.08x450 (sources vary depending on patrol base or taiwangun) to a 6.02x450.

If cyma made the cylinder volume a perfect match, I guess I should try a slightly longer barrel...
