I have a synthetic, semi hump-back. I got it in 2002. It does get treated a bit rough, but always gets well cleaned. It has seen a lot of swamp water, sweaty dirty fields and busted up some ice(unloaded, using the stock). No hic-ups.
The gas piston is hard to clean. The schematic shows all the parts of the piston, but I cant get it apart so I soak the whole thing in Hoppes for a while and blast it out with rem oil.
It is heavy, so a lot of walking will take its toll, but the weight is good to offset heavy loads for ducks, geese and even turkeys.
The price seems good.
I shot A-5's before I got the Gold and it has a similar feel. It feels a lot different than an 1100 or an 870.
