Mossberg 410 Hushpower Moderator Cleaning

[CillDaraVerminator]

Recently got my hands on 410 Hunshpower Mossberg 500.
Cracking little gun, my question is this, how do I get the mod off to give it a clean if/when it needs it.

Or when it doesnt need it just to remove it and open it up to allow trapped pellets or sheared off plastic wad out of the baffles.

Havent been able to find a video of someone taking theirs off the mossberg.

Any tips, links to videos or pics would be great.

Call the Biggin Hill Saddlery for advice - most came from there.

Must admit I’ve never taken mine apart, just cleaned it like a normal shotgun with a rod.

Let us know how you get on.

Hushpower suggest you shouldn’t but they will unscrew and it can be a pain to get screw fully home.

There are no baffles as such. The barrel is ported/drilled through and the moderator is just a sleeve really. So a hollow cylinder that screws to a threaded attachment lower down the barrel and it is held true with a ring of metal attached to the end of the barrel. Personally each time I use my gun I unscrew the mod, pull it off (which can be a character building experience…) and clean out the crap inside it. I usually gently scrape the crud off the barrel and rib with a wooden lolly stick. Cleaning the inside of mod is not easy, i just use a brass 12br bush to try to get most of the crud off the part of the mod that slides over ring attached to the end of the barrel. I’m wondering if carbon remover might act as a solvent for the crud?? Not tried it yet. But the mod is a tight fit and a little crud inside it causes me issues.
I put some sort of Napier gun grease on the ring and threads before I reassemble the mod.
It’s easier to get it apart just after shooting and before the crud solidifies and things seize up. When the gun is hot after firing a few shots.
You either have to be super keen/stupid like me and clean every time or say stuff it and never clean, like my pals who eventually have the mod ‘rot’ and barrels corrode badly (over years of use).
If the mod still comes off you are in with a chance, if it’s stuck you are stuffed, as far as I can tell.
My gun was second hand but in really good condition hence the reason I’ve faffed around getting the mod off. I just let my rifle mods fend for themselves and never dismantle them. But I don’t want to eventually knacker the Mossberg.

Not sure how to unscrew since rib is going through as seen here

Don't bother.

I've removed it on my 20B, not sure about the 410. There should be a small screw on the bottom of the moderator. Remove this then you can unscrew the moderator shroud. The part where your rib enters the moderator doesn't come off.

clean it by shooting .410 carrtidges through it....

apply a hoover nozzle to the muzzle if it turns into a "rainstick" (unloaded obviously!)
