Madbull Airsoft AEG 6.01mm Ultimate Tightbore Barrel 7075 Aircraft Aluminum (455mm)

"I put this barrel in my KWA SR10 and the improvement in accuracy was amazing. I am hitting people accurately at 175 feet. I use .28 bbs and at 100 feet I can hold a group around 3 inches with no problem. I have used several different types (6.04, 6.03, and 6.01) and brands (angle custom, madbull, ect.) and this is by far the best barrel I have ever had.

Pros: Increase accuracy and FPS
Easy to install
Same if not better quality and performance as a Prometheus for half the cost

Cons: I cant even think of any

"This barrel is a beast, I put this in my KWA SR10 with GEMTECH BLACKSIDE supressor, still have about 10mm left. Perfect. This thing makes my rifle shoot even harder and more accurate. It's not fair how accurate this thing is. Only concern is I think its thicker than a normal barrel because it took some effort to slide back into my rifle, not anything extreme but rougher than normal. Definately worth the extra $$ over the 6.03. Fast Evike shipping, great packaging. 5 stars. BUY ONE OF THESE

"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.
