Hey welcome to the forum! Take a peek it the mag well by opening the bottom plate and see if there is anything obstructing the mag follower or spring from coming all the way up the mag well. Carefully insert the follower and spring assembly back and close the bottom plate. Check operation of follower and spring with a poke of your finger to see if it moves freely....if so load the mag with dummy rounds and cycle the action to check for proper operation. If you still have a problem my reccommodation would be to call Remington for a warranty issue since you are dealing with a new rifle here. If anyone else may have other input on this problem please chime in. Good luck!
