let me start by saying i'm really not mechanically inclined. I bought my youngster a new 870 express. I polished the chamber, replaced the extractor, installed a new shell follower. I always shy away from used GBroker guns for fear of getting a lemon.

but it seems that an 870 is so simple even I could repair it, is it REALLY that simple? is there something besides the ejector(riveted) that I couldn't do myself?

thanks!
