Product: Black Python 363mm Tight Bore Barrel
Brand: MadBull

Review:
I've put this in my over modified M4 S-System.
I zeroed in my rifle a few weeks back and was able to maintain a 2.5inch grouping at 130ft. But keep in mind,
nothing on my weapon is stock so it's not just the barrel that made the fine results.

Since I've put it in I've noticed these pro's:
-Increased accuracy at greater distances;
-Tighter grouping;
-Good price for a good product.

The con's:
-You now need to use good ammo. (KSC Perfects or Excels). Which run a bit of money, but you don't need to
shoot as many rounds anymore, 'cause you can now hit more stuff with less
shots.
