Awesome, be sure to give a little update on how it performs. Been thinking about getting a 6.02 over a 6.01.
Compare it to whatever you have in it now,but remember not to switch out hop up rubber or anything. ZCI barrels are very good I hear,even more so after they've been lapped and polished
Waiting on a prommy purple rubber and element H nub to arrive to fully test it. The other barrel was a Madbull black python.
Kinda off topic here but how does your TM M4 perform Mack? Further more, do you have any pictures of it on the forum?
