Madbull is one of the top manufacturers in the airsoft industry, they are world renowned for their high quality products and their tight bore precision inner barrels are no exception. The Madbull Version 2 Precision inner barrel features a 6.03mm diameter for increased range, accuracy, and in some cases increased muzzle velocity.

Purchased one of these for my custom AUG H-BAR kit that I was building along with a Madbull 60 degree hop up bucking. What a fine piece of work this wound up being. driving tacks at the 25 yard range at the rifle range.
3" groups at 25 yards on full auto
tight fit into gun (adds to accuracy and keeps it from getting damaged)
aircraft aluminum is kinda light, I know I wont, but I felt like I was gonna break the darned thing

THese things are great.
So far, MadBull is the only off-the-shelf manufacturer I've seen selling a reasonably priced PSG1-length tightbore that isn't so tight that it lams up on 5.95mm pellets when it gets cold outside.
I'm looking at you, EDGI.
The barrel is lightweight due to its construction, and with the addition of a bore-up cylinder and used in conjunction with a proper hopup, will turn just about any standard-gearbox gun into a pretty hellacious DMR or countersniper weapon.
I currently have one of these in my King Arms L1A1-SLR shooting about 360FPS on .20s. I regularly load G&G .28's because of their precision and extra mass, and can group less than 15" at two hundred feet.
HIGHLY recommend MadBull's barrel series to anyone looking for a core upgrade.
Good material (7074 alloy aircraft aluminum)
Easy drop-in installation, as expected
It won't get the newspaper in the morning.
Madbull doesn't make a 618mm core for my RPK or a 116mm core for my Vz. 61.
