"I bought this barrel last week and with a few other accessories and they finally got in today. I'm upgrading my Dboys scar-h with this inner and some rail covers etc., and on the stock inner it shot about 150 ft. which to the average player is decent. Now it's shooting around 190-200 ft. and the fps jumped so much that .20's still rise with the hop up completely off.This is my first real upgrade for airsoft and I highly recommend it, I honestly didn't expect that much performance from it.

"Bought this about 5 months ago and have had nothing but good things about this barrel.
Except unless you're careful, this barrel WILL get bentb unless treated properly. I was rough on mine and I would still consider and buy a madbull before another brand.

Pros:
Light weight
Excellent grouping
Looks and feels amazing

Cons:
Treat it right or you will bend it like me

Otherwise excellent product

"I installed this inner barrel on my SRC HK-416, my airsoft now shoot's constant 350FPS and my accuracy increased dramaticly, i have grouping of 2.5 inchs at about 180 feet.

now my airsoft doesn't jam in the canadian winters

this is the best 30$ i ever spent on my upgrades


don't hesitate to buy this inner barrel

"excelent barrel, it increases fps slightly. my accuracy increased dramaticly, shoots consistently straight evey time. these barrels are probaly the best bang for the buck.

"This is a really good barrel, I put in my G&G blow back rifle (the GR16) and it groups the bbs real good. I shot it at 50 feet and the grouping was like nickel, so far I have had no problems with it and it is a great upgrade. Some places have the same barrel way higher price, Evike is the best place to get it and as a matter of fact I'm about to order another one for my other g&g rifle.

"It works great with my Dboys SCAR and the Matrix 190mm mock suppressor. It increases accuracy and range and maybe FPS, altough I haven't been able to chrono it yet. More accurate than stock 6.08mm, and jams less than 6.01mm. For $30, it is an inexpensive upgrade to your AEG.

"Great great great barrel. Mine came in black, which is super slick looking. It gave my gun a bit of fps increase and a definite range increase. Highly recommended.

"Amazing barrel! I have spent way more on Prometheus barrels and didn't get the performance that I get from this one!
As an airsoft mechanic, I have tried many different inner barrels and the Mad Bull Black Python is by far the best one I've found. I will never use anything else in my guns and will always recommend these to my customers.
I now have them in 3 of my guns...ICS AK74, SRC AK ADV, KWA M4 Free Float CQB. As soon as I find one for each of my WE HI-CAPAs the will get them too!
The Mad Bull red fishbone bucking works very well with these barrels. Be careful though, some guns don't "like" the fishbone buckings.

"Really Nice!
So I cut the size down from a 509 to a 229ish mm, it was slightly damaged because I did a horrible job cutting and dremeling, but even though it damaged it has better performance than my stock barrel!
Hes right, its anodized and it seems like its made of aluminum or tin, not a big problem because its lightweight! Compared to my brass stock barrel, its weight is about 1/2. Best part is, FPS jumped from 380 to 400ish. Good buy! I think I'm gonna modify the other half!

"Put one of these in my Classic Army SCAR Heavy replacing the stock barrel. My rifle now shoots frozen ropes and I am not even kidding. Ball after ball falls in the same spot. Definately a underrated barrel and a awesome upgrade for a cheap price. I combined this with a G&P max acuracy Hop up bucking and my gun is performing awesome. This should be your first gun upgrade a tight bore barrel and this one is very nice performing for a great price.

"ok so i have a jg dragon(the funky anime gun) and i have made a few minor adjustment to it but after putting this inside, its insane the difference!! i hardly could believe it when i shot in about a sq. foot area at about forty yards away! yeah unbelievable huh! i mean before it could make it forty yards but the bbs were EVERYWHERE!! but now its grouping is fantastic! i mean a sq foot is about all you need when a reg person is about that wide with camo stuff on! so this barrel is great!!

"I am so amazed by this barrel at first i was going to get that Prometheus barrel but it was to expensive so i had got this one and all that im going to say is dam this barrel is the best that i have seen and it makes my gun so much more accurate and upped the fps i can hit over 150 adjusting the hop up but over all this barrel is so worth the money


GET THIS BARREL IT IS BEAST 5/5!!!!!!!!!!!!!!!

GOOD WORK EVIKE AND THANK U FOR THE QUICK SHIPPING

"I got this wonder barrel for my aftermath ak-47 6 months ago along with a systema bucking. It is an amazing combo. The range and accuracy is incredible.

Pros
- Tight groupings (using ksc perfect .25g with no wind)
@ 65ft 1.5-2in
@ 120ft 3-4in
@ 200ft 8-10in
- Increased usable range
- Very lightweight
- Cool looking Mad Bull logo engraved on the side of the barrel
- Nice smooth black finish
- Very CHEAP!!!

Cons
- Seems as if it could bend if treated roughly

The service i got from evike was impressive. This upgrade should be the first upgrade anyone does to their gun. It is a steal and i recommend it to any one who wants a great barrel for an even better price. Thanks Evike.

"This barrel made my accuracy on my p90 a lot better. It decreased the size of the grouping a lot. I am able to hit people from 150 feet away easily Another pro is the barrel is black so it will not stand out. Overall a great barrel for a great price.
by Andre V. on 04/06/2009
"Great barrel for price. I bought one for my AK and i saw way tighter groupings and more range and more fps. GET THIS BARREL!
