Cleaning a scoped or open sight rifle is really no different in my book. With my inline rifles the first thing I do with them is break them down into their different components. The barrel, trigger assembly, the scope (if you use quick release rings), breech plug, ramrod, stock, and the ignition system. This is my method. Your methods might vary.
- remove the ramrod from the rifle.
remove any of the barrel lugs or what ever is used to hold the barrel and action to the stock.
remove the trigger assembly. Normally held on by one or two screws. Some triggers are pinned so do not attempt to remove them unless the manufacturer recommends it. Now remove the bolt and or striker system. I throw the bolt and or striker system into soap and water.
Using a breech plug wrench or socket set, or what ever you use, take out the breech plug. Many times these breech plugs can be tuff. If they are tuff, I have taken the rifle to the work shop. I then put the barrel in a vice grabbing it by the lug bolt section. Then with some gentle tapping, you can often times make them break free. If the breech plug is frozen in place, there are other ways you can persuade the breech plug to come out.
Put the breech plug into a soaking solution. I like to put the rifle into a dish pan filled part way with hot water and some dish soap in there. Because I am going to use that same water to clean the rest of the rifle.
With the rifle broken down, you now are really going to clean parts... So the first part I clean is the stock. I take a soft cloth and dampen it with some soap and water and wipe the inside and edges of the stock out. If the stock is wood, I do the same thing but use a soft cloth with some furniture polish on it. I wipe the inside out and set the stock to the side.
Next I take the trigger assembly to the pan with the soap and water. I then put that in the soap and water and with a tooth brush I scrub every possible part of the trigger I can reach. I also swish that trigger assembly around in the water with the hopes that the water will penetrate into the inside mechanisms of the trigger assembly and wash the fowling out of that. After I have done that I shake the trigger assembly out real well, trying to get all the water out of the trigger assembly. I then take that trigger assembly outside and using brake cleaner, isopropyl alcohol or carburetor cleaner I spray into the inside of that trigger. Watch your eyes here so that spray does not splash back into your face. These cleaners do a couple things, not only do they clean the trigger but they drive any water that might be in the internal mechanism out. After they are sprayed down I take them to the air compressor and using a hard PSI air blast, blow all the fluids, water, etc out of the trigger assembly. If you touch it down you will see it is bone dry and very clean. Take the trigger assembly now and put a few drops of a quality gun oil into the internal mechanisms.
I now clean the breech plug. As you might remember, the breech plug was soaking in soap and water with the bolt and or striker assembly. I take a stiff brush or an old tooth brush and I scrub the threads and face of the plug. Pay special attention to the breech plug as you want to get it clean. After I have that all nice and clean, I take and start using Q-tips and solvent and again wipe out the inside and outside of the breech plug until it is 100% free of fowling. This is then set to the side.
Some bolts do partially come apart. So if they do, them take them a part and clean all the parts. The striker assembly system is also cleaned in the water. After they are cleaned in the water they are wiped down with solvent patches and then dry patches. Set these aside.
The barrel is next. At the water tub I take a small cup and pour water down the barrel. I do this for four or five cup fulls. This will was out the major fowling from the barrel. Now with the rifle over the tub of water I take a breech plug brush. I put some liquid dish soap or hand soap on the brush, and then scrub the breech area, the breech plug area, working that soap into a good think foam. After I am sure the area is clean, I again, pour water through the barrel flushing out all the soap and fowling that the soap has picked up out of the rifle. Examine the threads inside the rifle. They will be spotless. Use the same tooth brush and scrub the outside area of the rifle around the breech. If you have a scope, this is a good way to scrub around the mounts and under and around the parts of the scope. Simply use soap and water. Then a little rinse and it will be nice and clean.
If the scope is removable, this is easy to clean with the water bath and tooth brush. Not by dunking it of course but carefully brushing if your rifle is like mine and likes to deposit fowling on the bottom of the scope. After that some solvent patches to wipe the scope down will make sure you did not miss any part of the scope. Set this to the side for later reassembly.
Now the barrel is taken to the bench and a solvent patch is pushed from the breech, through the barrel, out the muzzle. This patch will be wet and filthy. Do a second one. This might be a little dirty. By the third one, normally the solvent patch will come out clean and since it was solvent used, will also remove any plastic, copper or lead fowling from the barrel. After this I like to push a few dry patches through the barrel until they too come out spotless clean.
Now is when I oil up my rifle. The first thing oiled is the barrel of the clean rifle. That patch is then set to the side. I then put the breech plug back into the rifle. Be sure to either tape the breech plug with Teflon tape, or use an anti seize. I personally tape the breech plug then paint it with anti seize and replace it into the breech of the rifle.
I now wipe the trigger assembly down with the oil patch and replace that onto the barrel.
Next I wipe down the bolt assembly or the striker system and replace the bolt, or the striker, into the rifle.
Now using the oil patch I wipe down the scope and the mounts. I then replace the scope if it is quick release. If not pay attention and wipe the scope down well making sure all areas are covered.
Now I wipe the rifle barrel down. I put a drop of oil into the locking lug blocks. I also then replace the barrel back into the rifle stock. I then wipe the locking lug bolts and reattach the barrel to the stock. After this I wipe the ramrod off, then the rest of the rifle one last time and put it back on my shelf.
I am sure I have missed some steps but I hope this helps some.
