New to the Forum, New non working Marlin 795 owner question

Hello everyone, I like the way this forum is set up. Glad to be a member!

I bought a Brand new Marlin 795 from "Big R". I took it out for the 1st time today and the trigger is dead, I didn't even get 1 round to fire. It doesn't dry fire either with or w/o magazine installed.

I bought this gun to train my kids gun safety/handling/accuracy and they were quite disappointed when it wouldn't function.

Is there something easy to fix on these? I really don't want to deal with "Big R's" NO return on firearms policy.

Thanks in advance for the advice!
