I have a 500 that I am in the process of building but I hate the feel of it. I put a hogue 12" LOP stock on it and it is not comfortable. I doubt I can sell it now since I had to mod it to fit the magpul SGA sling mount on it. All the stuff on my H&R will fit an 870 so I was thinking of getting an 870 and swapping all the furniture on it. I see the express can be bought brand new for around 300
