Rifiled Barrel in a GBB

[ert]

I installed mine today in my KJW Sig P226 and it shoots really really sweet. I can't describe it other the the fact that it is straight and flat... like how everything should shoot. It's well worth the money I gave to Brian. That's for sure. I'd say it's probably the best upgrade I could have got for my gun performance wise.

I give these barrels 5 thumbs up... and I really only have 2 thumbs so the other two would be my big toes... and the fifth "thumb"... well... you can figure that out.

[ILLusion]

I'll put my 5 "thumbs" in as well to make it a total of 10.

If I could get them for every single one of my 80 million guns, I would.

As an interesting side note, I have a REALLY old school MGC Glock 17 Seidler Custom Race Gun and it doesn't have hop up, but it does have a rifled barrel. Range is crap, but the effective range it does have is very accurate.

I'd be interested to see about getting one for my AUG and my M700 if it's possible to find them. Please Illusion, keep us posted if it works out for that AEG.

oooo, on Power Edge they have these things for the VSR Gspec. Doesn't say what the optimal power would be though.

Looks like power edge has more barrels the WGS, and alot are in stock too.

ever seen a crossman colt model befor looks like a real gun mag pops out and in just like the real thing and it has a rifled barrel. I know for a fact that my counties law states that any object that has a barrel and receiver wich is ment to fire a projectile and is used in a crime is considered a firearm....dont ask

FYI

"Koba: "Since the BB is underpowered, its muzzle velocity declines if it touches to the inner surface of the barrel. Therefore, you cannot let BB touch to the surfaces of the inner barrel while inside it. But you cannot expect any effect from grooving (the “twists” inside the Tanio Koba Twist Inner Barrel) with that method. On the other hand, hop up rubber can make BB spin to up and down and run inside of smooth barrel in gentle straight zigzag course. This zigzag point of contact is affected by some variety of conditions like shape of BB or side gap of contact point with the hop up rubber. It changes each shot just little bit and there is a limit as long as there is a clearance of BB and inner barrel.

With this hop up effect, I made small difference in level with minimum air loss and make this difference in level as a zigzag contact point. This difference in level gives the regular direction bias to BB and the air current in the middle of the groove leads BB to the second contact point. BB doesn’t move straight precisely like a spinning trajectory, but just makes a regular bias trajectory making regular zigzag movement. In this fashion it keeps regular trajectory effect with the balance of hop up rubber. Therefore, it improves grouping quality, but it doesn’t improve the range and the muzzle velocity in comparison with the normal hop up barrel.

After all, the theory of so-called KOBA Twist Barrel is just something like a trick of “KOBA magic!” as written in PR or instructions. Even so, it became very popular in the world. I myself got surprised! I’m very glad about it."

Can someone translate all that into English? I broke my brain trying to read it.

We're not using them in crimes.
