IGB 16 inch barrel - anyone have DIRECT experience with one?

[cledford3]

I've been looking at the IGB stuff for a while and have some unexpected cash to burn - this looks like the time to buy one if they are worth it. I have seen the Steyr forum thread (linked in another GT thread about IGB) and the info there (poor quality control, lousy customer service) is VERY concerning.

Before writing the whole thing off I thought I'd post for opinions here from people who've had *direct* experience with these guys. AS in owns/owned one, shot one, know someone personally who has/had one.

I'm not really interested in starting a thread on the legalities of SBRs, stocks, owning 16",barrels, pistols and stocks, etc. I'd just like to know if the barrel system works or not with a g22.

Thanks,

Anyone?

I don't own one but I don't need to own one to know it's an idiotic design. You don't want that much inertia when you have a tilting barrel. Even if it cycles, you are putting a lot of stress on your pistol. There's a reason why semi pistols need a nielsen device for use with suppressors.

Lone Wolf sells these barrels in the US.

Whats a nielson device adn how does it work?

I never really thought of this, but it does make sense. If you want a carbine, pretty much go and buy carbine.

It is a device that boosts the recoil of a cartridge passing through a suppressor to unlock the breech of a semi auto pistol to allow the firearm to cycle. It is required to be able to use a semi auto pistol with a locked breech design. Those pistols that have a fixed barrel (beretta M9 style) do not need these as the slide works on blowback recoil.

That is a short version of what a nielsen device is. Do a google search for more info.

This may be a bit off topic but does the 16 inch rule mean a 16 inch tube? I ask this because on FN's SP90 part of the 16 inches is an elongated flash suppresor that is not rifeled. If were just talking about length could a hollow tube that is extreamly light be attached to a pistol and still fuction with the tilt of the barrel?

the IGB barrels, above 7.5", have a 'impulse chamber' that screws into the barrel right in front of the slide.

That is supposed to take care of the cycle issue similar to what is used to cycle a suppressed firearm with a floating barrel.
here is the link to the manufacturer's website:

That may take care of the cycling issue by using the gas to force the slide back, but this also greatly increases the stress on the lockup surfaces. It's a brute force way of making it "work" so they can sell you something that cycles, and only later will you find it's worn down your gun.

You still have too much inertia, that inertia will resist the motion of the barrel during cycling, where it has to translate both backwards and tilt up. The end result is much greater stress on pistol than it was designed for, primarily the lockup surfaces and the rails.

If anybody has this square peg in round hole contraption and has put more than 3000 rounds through it without problems, I will burn my Mechanical Engineering degree.

Do not play with fire :wow:

There is a much slower cycling because the barrel has more weight and the breech block on the barrel is a little bit different to the original.

No problems so far with this system.

elpresidente,
Do you have one? Does it work correctly?
Thanks, MLM

I'm also curious about this set up but I have never been really able to find anyone that "really used it".

I did the SBR and use their stock. It works. I then added a suppressor. It groups about 6 inches at 100 yards.

I am still in search for a better platform.
