Believe me when I tell you that I understand your frustration. I also have had to deal with defective Airgun issues as well. I have had problems from dealers and from the manufacture.
You obviously know they received it. Counting down the hours isn’t going help your situation.
I learned the hard way, the guys on here will tell you “two airguns is one and one is none”.
Brother, I am telling you that is the gospel! Just the nature of this hobby of not being able to go to the local “Airgun Quickie Mart” and pick one up or some parts for it, if you don’t happen to live by a dealer sucks.
I have been in that situation when my Umarex Origin broke, and I will never be in that position again.
Hey, you’re already in this deep might as well go all the way as crazy as that sounds.
PA has a great return policy, I know. It varies by air gun the better ones have a longer return window.
Find something else to look forward to and take your mind off of this.
Ask yourself, if I didn’t buy the Barra or what I know now what would I have purchased? and do it.
The Barra will work its self out.
