GSG STG 44 .22LR Barrel Question

[Ricard350]

Hi,

I just finished cleaning my rifle after its first trip out to the range and I have noticed something very strange after looking down my barrel with bore light shined thru it...

It seems that the barrel is made up with 2 parts that meet up about 2/3 of the length near the muzzle end.

Is it the way they are constructed or mine has a defect? If someone else has this rifle and can cross check if they have the same "gap" between the 2 barrel part....

Here is an image to visualy explain it




Here is what u see when looking down the barrel from the muzzle side U can clearly see a gap



On the 2nd image in real life u can clearly see a gap specialy when u start to check it from a slight angle... its not a illusion...

Thanks for checking
David

I'm thinking maybe because they use a same barrel p/n from a diffrent firearm like the mp40 or mp5 in .22 in order to save cost...

Looks like a ringed barrel. That happens when there a bullet stuck and another is fired behind it...
Have you shot it much?

 

[Ricard350]

yes about 400 rnds and 1 exploded / ruptured case.... but everything went good.....

 

[Ricard350]

gap is perfectly cutted and the rifling groove match ....

Just got back from the range and it worked perfectly and grouped very nicely at 25m

 

[Ricard350]

So anybody else has an GSG STG44 that could check it their barrel is made like mine?

I have a 1914 browning semi auto .22 with a ringed barrel and it functions flawlessly and is accurate as hell

Looks like a ringed barrel - that's what they can look like. If one didn't leave the barrel and it wasn't noticed, that's what would happen. If the rifling matches that adds to that. Can't imagine a company would every even consider trying to join two barrels like that, so it returns to the most likely option that it's ringed. Doesn't matter much if it shoots well.

Just checked mine, only 50 rounds through it, but there is no ring in my barrel.

 

[Ricard350]

Looks like its gonna go back for warranty

That is what your ring is from. When the one case ruptured, the pressure went out the chamber end instead of pushing the projectile out of the barrel. The first round you fired after the rupture would have created a very high pressure point between it and the stuck bullet forming the bulge.

To everybody on here, if you ever get a ruptured case, check the bore before you fire another shot.
