Possible issues in my new Vulcan .25

Hello everyone:I have some doubts, I will send you two links to videos, one that shows black and other silver hole, the black I think is normal, but the other?https://drive.google.com/file/d/15aJqjBJD6sCGhfNL1Qj4eKo3nArWyBK1/view
The other video shows that when you put the magazine it is off-center and you have to push it in again.https://drive.google.com/file/d/1URtZ8wUrQ7OJL7lOsxiYsIRI_FN15ysh/view
What the two videos show is normal or should I contact my seller? Regards,​

Pd: Sorry for my english-
 
From what I see my Vulcan was the same!
you have no issue or possible issue. 
The mag not being centered is not a big deal. When you push it back the other it clicks in place. When you push the the bolt forward the probe will align the mag. Mine was the same and it caused no problems at all.
The silver spot on the tube didn't look like hole to me but I can be wrong about that. Can you just post a pic of the silver hole. From video is just looks like small scratch of some sort 
 
"riazp"Hi,
Those are atmospheric bleed holes. You will find one hole on each end of the cylinder, they are are over the threaded part of the cylinder, also one hole over the regulator that is lined up over the two o rings that separate the high and low pressure sides of said regulator.
Thanks riazp, you are right, there are three holes, will not there be any problem that are visible?, I say it because of the dust or rain.

Watch this:

Thanks Matt!
Nice Vulcan, the moderator is a DonnyFL Sumo? I need one, is that good or the huggett is better?

When I have the Vulcan with the accessories, I will upload some photographs, I am waiting for the scope mounts.

I only did two shots because I do not have the scope installed, but once I have it I can tell how accurate it is.

This is my fourth rifle, second pcp and first bullpup, aesthetically I love it.

I was looking at the rifle exhaustively and I found a scratch on the inside of the moderator's exit, has anyone else happened to him?
Is it something to worry about?
