"This is my second hybrid. I also have a 229mm. They seem to be pretty well made and group well. It is nice that they can be fitted to the outter pretty well. I use these with ProWin hop-ups and Maple nubs. docB

"great barrel, the o rings really eliminate barrel vibration, immediately noticed an improvement in bb flight and the sound of the gun, my new go-to barrel

"got this to upgrade my G&P M14 because the stock barrel was corroding on the inside since i got it. its been shooting like crap since i got it - so i got this barrel for it.
some people give Modify a bad rep, but i must say, this barrel is awesome. considering price point, product quality, and the overall results, you cant beat this inner barrel.

- FPS, range, and accuracy significantly increased
- the seal the ribbed bucking and barrel groves create is ridiculously amazing. and the hop the buck creates is crazy
- with the stock m120 spring/motor, stock full cylinder, and a H-hop nub my M14 went from about 390 fps to about 420 fps.
- and as for the range, lets just say that the BB is flown off into the horizon before i can seen it fall out of the air.

- the added diameter of the "steel" portion of the barrel does make it a little harder to deal with, especial with the barrel spring. but all you gotta do is open up the spring a bit.
- being mostly aluminum, installation is a little delicate.
- being such a long barrel and tightbore, the air cushion is way to small to be effective in full-auto. BBs basically just fall out the barrel.
- the bucking can really hop the hell out of the BB. may want to use BBs heavier than .28g if youre already shooting more than 380 fps.
