Madbull Airsoft AEG 6.01mm Ultimate Tightbore Barrel 7075 Aircraft Aluminum (455mm)
by McKane L. Date Added: October 4, 2011
455mm MadBull Tight-Bore Barrel (6.01mm) - KWA M4A1

1.) - Shipping
Evike, thanks again for amazing shipping and packaging. Everything was secure and safely shipped. (Tracking number was very helpful) Considering the contents of the Aluminum barrel, I was a bit worried that it would get damage during shipping. Turned out perfectly. (Furthermore, comes in a secure Protective Tube)

2.) - Install
Installation is easy and straight forward. Equipped on my KWA M4A1. The Hop-Up Nub came out during installation, had to fix that a few times. But the install was a breeze. (Just watch YouTube Videos) - Get Lube, too, for all the parts and cleaning!

3.) - Performance
KWA comes with a 6.05mm - 363mm Brass inner barrel. I could hit a large bucket from 150ft about 1 or 2 times out of 10 from that distance (Using a 3-9x42 NcStar Sports Scope). With the longer (455mm) barrel and tighter 6.01mm the groupings were tighter. Hitting 4-6 out of 10 from 150ft. A solid increase in groupings from a long distance. At closer range(s) (50-75ft) the groupings are AMAZING! 2.5in - 3in spread. Granted, there were a few outliers BBs during Semi, the accuracy increases during FULL Automatic firing. A straight spray of BBs with high velocity. (Note 10.8 battery - NON LiPo)

4.) - Conclusion
A wonderful barrel by MadBull for the Price tag. I fully endorse this product. Looks sick too! And buy a silencer if you are installing on an M4. Otherwise the inner-barrel will protrude out.

Thanks again Evike! Good doing business.
