Clean shotgun O/U action

Recommended Posts

Had a look through the forums and can't find anything definitive on exactly how to do this.

 

Some suggest soaking the action in petrol or brake thinner, then blowing that out with an air line, then oiling and blowing that out then putting greese on.

 

Others say don't use an air line as it can know the mech of true...

 

Comments, suggestions or links to the "proper" way to do it ?

Strip it down and clean it properly ???

 

I am afraid Petrol OR brake fluid of ANY type would be getting nowhere near my guns!

 

Remove the stock "or side plates" carefully map out the action then remove the mechanisms and clean.as you go.

 

Don't forget to to clean out the firing pin chambers too! Cotton buds are great for that!

 

I give the action a quick spray of silicone, as oil picks up dirt!

+1 You won't get a better advice :good:

A rather famous gunmakers once told me how they treat the inside of their actions. A mixture of Vaseline and 3 in 1 oil to create a thin paste. This is then 'painted' onto the internal parts using a stifish childs paint brush. I have used this method on my guns, with the exception of my auto's, for over 50 years without any adverse effects or wear issues. I can safely say that, if required, the internal parts can be readily wiped clean, should the need arise and I have never had dirt or grit mixing with the 'grease' to cause excess wear. I still use grease on the hinge pin/s and knuckle and have never had a gun 'shoot loose'.

Blast the mech out with an OIL based penetrating oil or gun cleaner like napier or legia or let the whole thing soak in a tub clean it all off with rag cotton buds anything you have, paying attention to the area where the firing pins come out,I was surprised how much crud comes out of here and how little crud there is on the rest of the mech.

Use a fully synthetic motor oil I use castrol 5 w 40 and give everything a very fine smear with the oil ( this oil sticks to metal and never dries) on moving or sliding parts you can be a bit more liberal wipe up excess.

High temprature grease like copper slip on chokes.

Everyone has their own ideas,I have been in engineering for years and not much can beat these modern oils,we never use silicone as a lubricant because we are told it goes tacky and can't handle heat and runs, oils can handle huge amounts of heat and doesn't lose it's properties easily and stays in place

No doubt some will ridicule my method but I've never had a problem from doing it and learnt it from a mate in the army.

 

Strip the stock of the action and replace the bottom plate if it's a side by side. Then boil it in a saucepan of water for 15mins or so. This melts all the old grease/oil and the bubbles/hot water get the majority of the crud out, mud, grit etc. Then gently blow the water out with an air line, the hot metal will dry it all off very quickly. I then lightly oil the springs, sears, safety, top lever, moving internal parts etc. with 3-in-1 oil or gun oil, grease the moving bits where the barrels rotate and reassemble it.

The silicone I use is a spray! It gives a light mist of silicone but does not become tacky! It is a good lube that will not pick up contamination from dirt nor metal particles!

Oii works its way into the actual moving parts, coating the load bearing surfaces - and stays to protect the surfaces even under pressure and movement. Motor oils are specially designed to do this and prevent metal to metal contact/damage. I'm not convinced silicone can/will do this as well. The oil/vaseline mix is indeed a long used mix that has been used/recommended over the years, but I suspect modern synthetic motor oils are even better on the metal. Use sparingly though and avoid the wood.

I was given 2 'don't do this' rules about cleaning/lubing the action by a gunsmith. 1) Never, ever spray WD40 in there and 2) Never, ever use grease in there. He didn't mention silicone but, speaking as an engineer myself, I can guess that he'd say "Why?"

 

You really don't need to use any fancy pants methods or products. White spirit used with a small brush is a perfectly acceptable way to clean out any powder residue and dust. You can use an airline to dry off but keep the nozzle at least 18" away and watch out for any moisture afterwards. The only lubrication the action ever needs is a drop or 2 of light oil on the pivot points and metal to metal contact areas. The important thing is to use minimal amounts; less is always more when it comes to lubrication.

 

Miroku and Browning actions are much more prone to dirt ingress than the modern designs such as Beretta, especially in the firing pin channels, but once every 15K rounds should be enough.

WD40 is quite a good cleaner and does disperse water hence the name 'WD' but it only contains a tiny amount of oil and it's just not any good as a lubricant. At the same time when it dries it leaves a residue which makes it a reasonable short term rust preventative but it's absolutely not what you want inside a gun, especially around the inertia block.

 

WD is fine for light cleaning the barrels or wiping down the outside, especially after getting wet, but I would never let it get in the action or into the cocking rods on a Beretta.

I was advised against using silicon on metal to metal surfaces when I was rebuilding my Webley Falcon as apparently it modifies the molecules of the metal and causes friction and wear.

Not being an engineer, I don't know true that is...

Silicon oil between two pieces of metal moving will create 'Pickup' tearing the metals apart very quickly.

I see it a lot at work (I'm a Engineering Inspector). Just the same as screwing stainless into aluminium.

Ben Taylor of the airgun company BTAS Wrote an article about it with pictures from his lathe destroying metals using silicon oil.

I wouldn't have the stuff in my workshop.

Everyone has their own ideas but just to point out a couple of things.

Machine oil or 3 in 1 type oil will do the job but a modern hi tech synthetic engine oil will do it better.

We use silicone in engineering to stop things sticking together basically,usually non metallic parts that don't rub together, never as a lubricant ,it gets warm and runs,goes tacky, and doesn't adhere to metal as well as oil.

a quick way to clean without stripping the action (which i have done with no adverse affects) is to pop it into a home ultrasonic bath like the ones that maplin (and aometimes lidl/aldi) sell.

 

cleans out the crud, and leaves you free to re-oil with your chosen lube....

 

it also does a bloody good job of bringing the action back up to its original splender.
