I got my barrel and installed it today.
I test fired it and unfortunately it fails to extract. The lack of an extractor cutout on the barrel is no good. How do I fix this?
It was made clear that I have to cut a groove into the barrel?You need to have an extractor groove cut into the barrel - that was made clear if you ordered the barrel by itself. A gunsmith needs to install it and tune it.
Also - by not pinning your stock you no longer have a non-restricted firearm.

The OAL is exactly 26" with an A2 flash hider installed. I will probably print a new buffer tube that doesn't allow the stock to collapse shorter than 26".

Not *super* difficult but certainly not a novice job. The two things we have noticed when testing / tuning is to polish the chamber really well and cut the extractor notch properly. Other than that I am not giving advice or instruction on the install in case it goes sideways and you want to hold us liable. Sorry.
Yes It was made quite clear that a extractor cut was needed to be made. FYI you posted a picture without a FH installed, so better start printing and or pinning asap, or calling to register it as a restricted.
Don't I have 30 days to register it?
Don't think so. So start pinning or start printing ASAP.
I pinned the stock open until I print a different one that doesn't allow it to collapse beyond 26".Don't think so. So start pinning or start printing ASAP.

I filed a chamfer into the barrel. I tested it with CCI quiets (710 fps) and it extracts the case but but the case gets pinched in the ejection port by the returning bolt carrier. I tested it with the regular CCI subsonics (can't remember the fps) and it cycled fine. I don't think I've ever fired CCI quiets in the GSG with the original barrel so I don't know if it cycles those anyway. I guess the quiets are too weak to cycle the GSG with a 9" barrel.I used a flat file to chamfer the edge of the barrel where the existing extractor cutout is on the side and it ejects fine. (if youre looking at the breech body/barrel its the cutout at 3 o'clock). Wasnt willing to pay a smith to file down some metal.

I'll test supersonics tomorrow.
Another issue I've noticed, which is not barrel related, is that the plastic nubs in the stock housing are getting worn from the repetitive removals for disassembly. This loosens the fit of the housing which doesn't have a screw on the top part so it wobbles a bit when pressed against the shoulder pocket.
Just dropped mine in the mail to you guys today. woot woot.
Do we get the stock barrel back?
VERY HAPPY!!!![]()

Did you use a crush washer to torque the flash hider?
Did you hand tighten the thread adapter and then clamp it while torquing the flash hider?
I'm worried that applying CW torque on the barrel will loosen it because it is CCW threaded into the chamber block.
