I put about 250 rounds through it the other day at the gun range and the thing looks pretty badly worn. My 870 remington is no were near is this, it still looks new outside the fact of some cycling wear.
Lower priced firearms ALWAYS use lower priced steel. Lower priced steel is softer and shows more wear marks in a much shorter time than then better steel in the higher priced firearms. That is why the Perazzi guns and Krieghoff guns last over 100,000 rounds between tune ups and the barrels last for generations of high volume shooting.
No offense, but, you gets what you paid for...
