Madbull Airsoft Black Python 6.03mm Tightbore Inner Barrel for AEGs (Length: 300mm)

"This barrel does soooo much for my CAm15a4 for only 29.99
My .2 grams can touch targets out to 120+ ft no problem
the barrel also up my guns fps from 330 to 345
On auto fire the grouping of bbs is so tight i hit my cuzin on the same finger 5 times with the pull of a trigger.

Overall, for 29.99 you get a lot more than you would buying all to other internal upgrades...
oh yea its its easy to install too

"an amazing barrel, increased the accuracy of my jg m4 s system exponetialy, but i did have to get a barrel extention to cover it up.

"THIS IS THE BEST INNER BARREL!!
I had a stock A&K Masada that preformed slightly better than a normal AEG. Once I installed this inner barrel though, the range and accuracy had made a vast increase. This is a must for MR based airsoft guns. Now since the rest of my AEG is stock (running at roughly 380FPS with .20g bb's) I can reach pretty far out, but with the lower FPS and lighter weight bb's, the barrel is not able to preform to its true potential. AKA you will need to upgrade your spring/hop-up. Also, this is my first inner barrel, so I don't know if this is the "one", but wow is it fantastic.

PROS:
Increase in Range
Increase in Accuracy
Good for higher FPS/g bb's

CONS:
I got nothing

"This is a good barrel, but not as good as I expected. I installed it into my CA M16 which had a stock 6.08 inner barrel. The new barrel did increase the range by around 10 feet and the accuracy is twice as good now. The downside is that the gun is twice as loud now. However it's worth the investment if the small improvements are a big deal to you.

"I put this baby in my barrett, and it was amazing. Had it shooting 440 fps w .28g bbs.

One problem I had was that the box they sent it in, had no cushion or anything in it. :(

"pretty good barrel it has noticeable accuracy difference then my stock G&G barrel. not by much but once the bbs get past about 100-125 feet you'll see the difference. for $30 you cant go wrong but still, it's not the best. dont get my wrong though, its really good.

"I ordered this and when i first got it, the barrel itself was severly bent, so i shipped it back, and evike again has not ceased to amaze me, they sent me a new one within the next week. when i got the good one in my gun i noticed a HUGE difference, FPS, distance, accuracy, and even the sound. im giving it a four only cause of the bent problem but other then that i'd recomment to any player

"One of the most recommended upgrade for your gun

Pros
- Cheap price great deal!
- Mad bull engraved on the barrel
- Light weight

Cons
- Scratches easily
- the barrel may crack if you try to trim the length

"i rate middlish because when i got this put in it started double feeding no idea why

"For some reason it doesn't work for my setup.
I have a KA P90 with stock hopup and "Mad Bull 60 Degree Shark Hopup Bucking"
and I have 2-3inch spread on 14 feet distance. And with stock 255mm barrel it is less than 1 inch. This is very frustrating considering that I've spent $60 (with purchasing mock silencer to cover the barrel) for that upgrade,
