"absolutely a great barrel i purchased this for my echo 1 timberwolf and it works great. i did not us the hop up rubber that came with it. instead i purchased a 50 degree maple leaf rubber and believe me it has done me a great service for buying this upgrade.

very accurate
good range...for a pistol

none that i can think of

"I got this for my WE18C just to see how much it would actually improve my groupings. After installing and testing, I immediately went back to Evike to purchase another one for my WE F226. In all seriousness, this could very best purchase for your GBB pistol, besides the purchase of the pistol itself, of course.

In order to discover the best barrel-bucking combination, I tried the barrel and bucking separately from one another. I put in the barrel and gained 6 FPS over the stock WE18 barrel; though this wasn't substantial, the grouping decrease was. Previous groupings: 2 feet spread at 50 feet. Groupings with this barrel: 4 inches at 50 feet. Astonished, I decided to try out the bucking (which has a mound that is kind of like a combination of a W and V) with this barrel. I gained another 10 FPS, and my groupings decreased to about 1 inches at 50 feet (I'm not even kidding!).

The only problem is that the bucking will only hop .25g BBs when all the way up, but this is a very easy fix with a little DIY. Take the plastic holder-thingy from six-packs of soda, cut a small rectangle out, and put it between the hop up arm and the bucking. This will give you more range for adjustability, therefore allowing you to use heavier BBs.

Now, my WE18 is Marui-performance status (and yes, I've owned a Tokyo Marui, so I can compare them). I get about 321 FPS with .25g BBs on propane with 86 shots per gas fill (though this barrel and bucking won't affect that) and have an effective range of about ~180-200 feet.

"This 6.01 ttb inner barrel is great replacement/upgrade I got it for my Echo1 TimberWolf being the right length. Came with a MAPLE LEAF BUCKING!!! _----pretty cool right? I know :D
Has a great finish, since it's a tight bore I do recommend cleaning after use.

-Good grouping
-Fps increased abit
-Range increased a lot
-Likes heavy bb's .28 and ^
-Easy/fast installation

-Cleaning more frequently (Not a con to me but people are lazy)
-No instructions (but wasn't hard to look up)

Other notes
This item came well packed in a study plexi-tube with rubber end caps
