so the gas tube on my rra tactical entry has come loose… i able to push it up and down. is this normal?
Yes it needs some play .
Loose from which end?
The front is held in place by a roll pin and can’t come loose.
The rear is held in place by the hole in the receiver and can’t come loose.
A little up and down play is good and shows that it’s not binding?
its loose at the rear end. does not move side to side though. only up and down, and when looking from the end of the upper reciever i can see a little daylight where the tube meets the hole.
