Storing a rifle with moderator on

[Sheamus]

Only reason for taking off moderator spells condensation. Damp air turns into water when cold material meets hot or hot meets cold material. Water drops may react with carbon and then rust and pit.
There are several ways to fix this natural law. One is to always remove moderator after an outing, another is to see to that both that gun and moderator have the same temp when moved into cabinet. If gun is placed on f.e. a radiator or open fire place a few hours before cabinet there will be no issue. If living/shooting in a very damp and salty area it pays off to go for stainless steel barrel material and titanium moderator.
Every time moderator is on or off there will be wear to the barrel thread. In the end moderator will turn lose or bend.

I very much doubt that my JetZ will ever bend. Not even if I drove over it with a truck

Why is it everyone worries so much with centrefire rifle but I bet most people can't remember the last time they look the mod of Their rimfires!

As everyone has said their piece I will add the full reason why a moderator should be taken off a centre fire rifle after use.

When the rifle is fired the moderator gets hotter than the barrel, (smaller mass), even after one shot. So if you leave the moderator on the rifle condensation will form in the moderator and run down into the barrel especially if the outside atmosphere is cold i.e. winter time and you bring them both into a warm house. Remove Mod. and let them both dry before putting them in the cabinet.

The reason why a .22 rimfire is not prone to barrel pitting or rust is that .22 RF does not produce as much heat as a C.F. when fired so the temperature differential is not so great between Mod. and barrel.

Do what you want, it’s your cash your wasting

Why take the risk?

Having bought a 2nd hand rifle that on inspection had thr front half of barrel pitted because of a mod left on ....just don't do it full stop

I take the mods off all my rifles, centre fire, rim fire and air rifle. They are taken off as soon as I get back to the car.

Question for the knowledgeable. I know I shouldn't leave a dirty mod on my rifle while in the cabinet, but will there be any harm done if the mod has been stripped, cleaned, dried and put back on prior to going back in the cabinet? As far as I can see it should be OK? For info, I put my rimfire mods in the ammo safe to split the parts of the rifles, but the CF mod won't fit and resides in the bottom of the cabinet in a sock!

I keep my Mods in a separate safe ! The gasses and burnt powder residue attracts moisture . realistically moderators pose no risk to the public no matter what fools say . How many criminals have a moderator home made or otherwise ? Not many at all i guess because the report is not silent and the concealment it far more difficult ! the Police imo kept them on ticket because its an easy pay day !

Condensation occurs when a cold object enters a hot and humid atmosphere, like your home or car. Not the other way round. You don’t get condensation on hot metal.

Thank you moeggesit for correcting me I have had so many interruptions of a serious nature that I should have taken the time to reread what I had written and correct it before posting.
