For: (Discontinued) EDGI 6.01mm Precision Inner Barrel for M4 (363mm)Product Information:
This Barrel is absolutely amazing!
I personally know the man/company who makes and designs these barrels! Actually got my first one from one of the guys on his team.
As of right now, I am using this barrel for my KM4S Tactical and WOW does this barrel improve the accuracy and FPS of my gun.
Just because it is an 6.01 does not mean it will jam. As long as you are using the correct BB and lube your fine.
5star is an understatement for this barrel
Most professional barrel out there.
FPS went up
Accuracy went up
Just have to clean a bit more....no big tho.
