"Picked this up for my CYMA M14. My mistake for buying one apx 3cm short, BUT I installed it anyways as well as a new Hop-up Bucking. I had a fair grouping at 50m before changing at roughly 8 inch spread. New Barrel and Hop, it's about 3 In spread. (when the wind isn't whipping) Very happy for my DMR build.

"Upgraded my ICS MP5A4 with this barrel. No mod needed

"Fantastic barrel at a low cost. These do eventually scratch up on the inside, but it takes TENS OF THOUSANDS OF ROUNDS to do this if you use quality BBs. I have built DMR's, assault rifles, and CQB guns with these barrels, and they've all shot absolute lasers.

"Mad Bull Black Python 6.03mm 300mm:

After reading the reviews i went out on a limb and got this barrel for my Cybergun Scar-L. I can say nothing but good things about this barrel. Finally got out to play and just swapping in this barrel increased my gun by 30FPS! The groupings are way tighter and it makes my gun shoot like a laser.

-boosted FPS
-groupings are way tighter
-range increase
-looks tactical
-all around great upgrade
-fair price

"Longest barrel iv bought, don't expect to use it indoors. My second Black Python barrel. Swapped this one into 2 different m4's and increased range in both with 2 different hop ups and a mix of other parts.

"I installed this on my CM16SRXL and I love it. Combined with the madbull red bucking I gained 30-40fps. I definitely recommend this for anyone looking for a quick way to increase the effectiveness of their gun.

by Peter M. on 11/08/2017
"I installed this onto my G&G Combat Machine CM16 Raider and it is incredibly accurate! I highly recommend this inner barrel as it's definitely worth the money!

"I pretty much only run Madbull tightbores because they are so awesome and low priced. I've seen other barrels that are supposed to be so much better, but at $80+ I'll just stick with Madbull for $30. They work great, and depending on your build, can definitely up you range.

"I have had this barrel for about 2 years maybe 2 and a half now. it has always been a great barrel! but now I think the Teflon coating towards the front of the barrel is flaking off. oh well. for a $35 barrel, amazing performance
by Eli O. on 05/21/2016
"The barrel is great, really helps range but and accuracy for aegs but it will slaughter your accuracy of you run it in a hpa gun
