SEND THEM IN ! GSG-16 update for Dlask Arms Corp.

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?

edited to remove bits about an extractor groove as quoted below - I must be imagining things. According to Dlask a gunsmith needs to install it and tune it.

Also - by not pinning your stock you no longer have a non-restricted firearm, it is now restricted.

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.

It was made clear that I have to cut a groove into the barrel?
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".

Pretty sure a screw on flash hider cannot be used to calculate OAL, but YMMV....

I like the look of what you did making a buffer tube for the AR style stock - looks good.

Somewhere in the lengthy threads regarding the 9 inch barrels I thought there was a post that a gunsmith had to cut an extractor groove in the barrel.

I must be imagining things though - looking at the barrel they installed for me there is no groove cut in the barrel..... but there is a slight chamfer at the bottom of the barrel where the round will feed into it.

FWIW they say on the preorder page I linked that self installation they don't guarantee the rifle will function.

Quote from Dlask
"These barrels are to be installed by either us (installation and tuning is an additional $100) or a licensed gunsmith. If you install it yourself we do not guarantee the rifle will function."

Found here at the pre-order link:

JoeShmow, it sounds like you need to either have a gunsmith look at it OR send it to Dlask for them to Re & Re...

I send mine to Dlask for this exact reason, I wanted the rifle back tested & with a function guarantee. Fingers crossed my GSG16 runs like a hot damn when I get it back.

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.

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.

Don't I have 30 days to register it?

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.
 
Well it functions awesome. just put 400 rounds threw it. only had a couple of problems with the drum mag. i have 5 stick mags, all were perfect. mixed old ammo. love this gun. gonna keep it forever. thanks dlask

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'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.

CCI Quiets won't cycle even with a stock 16" barrel. Ive tested HV, SV, HPs and all function fine. Just not the Quiet 22s.

Anyways a 9" barrel with CCI quiets will negate the quietness of them. Them out of my Buckmark is just as loud as SV.
 
VERY HAPPY!!! :dancingbanana: :rockOn: :ar15:

THANK YOU DLASK!!!

Cheers

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.

A crush washer was included with the A2 flash hider. The slots in the fh were about 1/2 a turn from being in the correct position. I did not clamp the thread adapter. I carefully turned the fh to top dead centre noting where the markings were on the bottom of the Dlask barrel. Nothing moved.
 
Hello Leigh, I have sent an email regarding my pre-ordered barrel. Since I was out of the country with very limited access to the internet and telephone, I couldn't respond earlier. I also tried calling but no luck. Do not know how thecorona virus situation is affecting the shop.
Any way, my order # is 17248 placed on Dec11th.
Thanks.
