Yea, more like Spackle I think.
Buyer- beware shouldn't cover flagrant lies, and sneakily-concealed defects. Take the cheat to court, and sue. If that was a car, and it said, "Brand new transmission", when the transmission was an old piece of junk with rust on it and no fluid because 2 holes were drilled through it, then no-one would expect the buyer to suck it up.
"Do not always rely on the description to be accurate. I’m not trying to blast the seller of this gun all his other feedback is positive, I don’t know what happened here, but please take note and learn from my mistake. If you have any questions or would like any other pictures please email me. Thank You for your time and happy bidding!"
I just finished 3 months shopping for a used car, and this guy needs to Suck It Up and damned well blast that seller, or he doesn't understand what 'feedback' means. He should simply go to a gunsmith, have the gunsmith write up an inspection explaining the rifle is unsafe, ask for his money back, and explain that lawyers are coming, along with possible charges, if money doesn't trade hands soon. In Canada people have gotten $7-9000 for emotional distress from horribly bad cars, misrepresented as spanking new. In the US it would probably be closer to $70-90,000!
Just so frustrating the sap is apologizing for the ass who ripped him off, and afraid to slander the crook's 'good name'.
