Just watch for the spring under the cap. Just Keep some downward pressure on the cap while unscrewing (think jack in the box when the lid opens. I can take pics if you want. I like my mossbergs. I've got both the Turkey version and home defense one.
Glorified boat oar IMHO..........................and I've owned 3 Mossturds in the past. But if you like it!!!!
I was going through my guns yesterday cleaning and realized I have 500 410 that I forgot about. Bought it for my girls to is end haven't ever shot it. It's a 500e, I'm kinda bad shape but will be a good gun for them to shoot and maybe get a squirrel.
