grizzly mag question

[ecotopia]

I was wondering if its normal that the tube that is suppose to hold shell on regular pump shotgun is a very little loose near the receiver?

this tube stand only for securing the barrel deep in the receiver right? is it suppose to be weld in place or there is some kind of lock pine that keep the tube in place?

Pretty sure they're normally pressed in or brazed...wobbling around would not seem normal to me

solid as a rock on my new grizzly-mag here. I see no reason it should be moving anywhere at all.
