my dads 12 gauge is a 66, and has been USED, not beat on, but used, and there is zero issues with it, and none have ever occured... mine is from the 80s i think, zero issues, and the other one is my dads 20 gauge, likely from the 70s, zero issues with it...

the 870 IMO is the best pump shotgun ever made... and when i can find deals on Wingmasters, i buy them... all of mine have come for 400 and under...

id pick it up, you will love it... i threw a high viz rail sight on mine, and it actually helps a bit as well...
