Been playing support role for a year now and love it so much I took the plunge into a g&p m249 and want to do some planning/shopping for upgrades. Was thinking of getting it r hopped so was looking at either a promy 6.03 or those modify 6.06 barrels. Reason for the 6.06 is my echo1 pkm comes from factory with a 6.06 and it shoots like a dream for a stock LMG. Any suggestions on which is better from you're experience is greatly apreciated
