Tell me what you think would have happened--I bought a new 243lr upper on gun broker and as I'm prepping for the range, I decide to remove the bolt and sight down the barrel, I see nothing, get my cleaning rod out and there is a dirty patch stuck pretty hard half way down barrel, cleaning fluid had dried, took a pretty hard shove to remove. I'm thinking that is nothing I would have wanted if I had fired!! Keep in mind it was sold to me as new upper. It goes without saying, always check that barrel on a unfamiliar rifle, but do we always, I'm thinking no, we don't--well I dodged a bullet this time, but what do you think-I saw a shotgun fired that had snow stuck in end of barrel. What kind of feedback do you think I should leave for seller??
