Thank you for this video. I recently purchased a 46MB which looks to be complete except for the front sight shroud. It is in remarkable shape considering it is at least 70 years old. I can't wait to check it over so I can put some rounds through it.

[@capthal-rs9mq]

You can get the hood for the front sight at halvinsales.com .the cost was $8.00 + shipping. Well worth having it will improve your sight picture

[@marksmith9194]

Great video. Thanks for sharing. I was given a 46 m b. I am trying to get it back to its original state. I need both swivels, the S130 peep sight, and the shrouded front sight. It is drilled for a side mount scope, but I’m unsure which mount will fit. I will likely put on a 3/4 inch scope. I’m looking forward to getting it all put together.

Check with Havlin gun sales on the internet. They are very knowledgeable on Mossberg rifles and carry a lot of parts for vintage guns. You might check on ebay and also gunbroker.com for parts. Good luck. Capt Hal

My mom bought me a Mossberg semiautomatic in 1945 when we moved to the Iowa farm. I left it on the farm when we moved to CA. In 1951 I went to Montgomery Wards to buy another, it wasn’t in stock I ended up with a bolt action. Both my old Mossbergs had stock fed ammo. Now I’m not sure what models or numbers I had.

[@capthal-rs9mq]

The first model was most likely 51. The 151 did not come out until around 1948. If you bought a gun from Montgomery Wards, it is most likely had a Wards model number. Even though the gun most likely was made by Mossberg. Back in those days, Mossberg made guns for a number of different stores. WARDS, Sears, Spiegel, ect.. Good luck. Capt Hal

@@capthal-rs9mq, thanks, I have a 151M, with the cone type bolt-screw. I didn’t know where mom bought the first one I stayed home when she came home with the gun, she told me to go put rabbits and Squirrels on the table. After I left that one on the farm, and moved to California I went to Wards but they didn’t have the semiautomatic but they did have the bolt action which I bought. My son has it, I’ll ask him if it has any ID on it, and get back to you.

[@mattmurray5625]

Again Thanks for your help on the stock, what should i use to clean up barrel and sights? i don't want to screw this vintage gun up.

[@capthal-rs9mq]

There are a lot of different cleaners for gun barrel. Not seeing the gun it is hard for me to tell you what to do. If your finish is only minor deterioration some people don't want to change it. But you have minor rust, there are products out on the market to help to remove. you might want to check with a local gunsmith. Now if it is major, you can re blue the whole gun. There are kits available to do that. Or this I mentioned in one of my other videos I used a product called Duracoat. It is a spray on paint product . Check the internet. Check KZbin for videos. Good luck

[@michaeldickerson873]

I have an M46(b) I.ratty rough shape. The magazine tube was missing and I found a used one that matches perfectly. It had surface rust on the metal, especially on barrel around front sight ramp….have it looking pretty good and the internal rifling looks real good. I’m still having problems with not consistently firing a round. I’ve cleaned the bolt, which requires removal of Mossberg rear sight to even get the bolt out of gun. I’ve cleaned the bolt spring and firing pin and still things are hit and miss. I might try to replace the bolt spring and firing pin and see if that makes any improvement…. It is sad that there are not many ole time smiths that work on these log gun Mossies.

[@capthal-rs9mq]

I think you are on the right path. Check the spring and firing pin. Check with Halvin gun sales on the internet. You might consider the ammunition you are using. I just wonder about some of the manufacturers today. Good luck. Capt Hal

Hi again, you have been very helpful with my Mossberg 46m b. I was wondering if you could help me with what is the best thing to use to bring the stock back to life? its not in bad shape, also the barrel and sights. Thanks for your help.

[@capthal-rs9mq]

I start by cleaning the wood with some alcohol. I try not to remove the finish. I then like to use tung oil. You can get it in high gloss or satin finishes. I have video on maintaining of your old guns. Check it out. There are a lot of gun finishing kits out there. Most have you first to remove the existing finish and sand the wood. I prefer to keep the original color of the wood and some of the blemishes which add character and may have a story to tell. I have refinished a couple of my guns. Check out video I did on my Mauser and another one on a mossberg M51 flat back (2 part) in these I finished the barrels and the material I used. Hope this helps.

[@mattmurray5625]

Thank you for the feed back. I plan to keep it original, i just wasn't sure if the S-130 was an original piece. I finally fired it an amazing rifle. I was also wondering if you know where i could find the sling for the 46m b. Thanks Matt

[@spiropatros2471]

I purchased a m46, I believe. It says United States property. M192 1947. Lend lease I suppose. All together. Terrible trigger pull, maybe 10 to 15 lbs. I need to find a manual on how to adjust it. English proof marks all over the metal. Missing fire bead. Need help to adjust trigger pull. Thanks Spiro

[@capthal-rs9mq]

Spiro Are you sure you have model 46m. Only 42mb were sent to England as training rifles. And they should have a serial number on it. Does your gun have a 7 shot magazine that loads under the gun. That's model 42Mb. The model 46m would have a tubular magazine the load near the muzzle and holds about 15 rounds of 22 long rifle. As for manual, l believe none of these rifles ever had manuals. You can find parts diagram, but I have never seen a manual. But if you separated the barrel from the stock, you should see a screw located just in front of the trigger that should help to adjusted the trigger pull. You may not get the adjustment you like, but remember these guns were made as training rifles and most military rifles have a stiff pull. If you sent me the serial number of the rifle I should be able to tell when it was produced. If you are interested. If you have any other questions just ask. If I can not answer your questions I may have other people who can.

Great video, always like the older rifles. I have a 46M-B. I haven't found a disassembling, cleaning and reassemble video. Was wondering if I just clean the barrel? The firearm was given to me by a close friend. I'm not familiar with the steps I should take to clean my 22. Thanks a bunch!

[@capthal-rs9mq]

I clean the barrel after every use. The internals are all open and be cleaned with out disassembly. The bolt can be disassembled by unscrewing the back part of the bolt, just make sure you have the bolt handle unlocked with the firing pin release so the pressure is off the firing pin spring. But even that can be cleaned without disassembly. There may be some video on disassembly of other mossberg models which are closely linked to the model you have. Thanks for watching. Capthal

Are you saying that you are looking for the front sights for your gun? You might try Ebay. I have found some of the parts that I need for my mossbergs. The only thing bad is the cost. It is amazing the cost for some of the parts. But what can you do. You might check with Halvin gun sale. Com. They carry a lot of parts for Mossbergs. And they have a lot of knowledge about Mossbergs. They wrote a book on the subject. Good luck.

I saw some videos were there are different front sites hidden in the gun. Maybe I miss understood the video.

[@capthal-rs9mq]

The front sight you have seen it the type of front sight the were on the 1940s to the early 1950s. This sight was a mossberg design and they were the only manufacturer that have that design. If your gun doesn't have that type of sights they may have been replaced by the former owner. Hope this helps.

[@mattmurray5625]

Thanks for your help. It mounts perfectly to the rifle, but I’m wondering if this is the scope that goes with the 46m b? Or was used with the Mossberg & sons 46m b. If you know what actually went with this rifle, that would be helpful. I will try to send a picture.

[@capthal-rs9mq]

Matt. Mossberg developed their first scope around 1935. At the time, there was an interest in use of scopes in the shooting community. Mossberg made a number of different types over the years. Mossberg sold their rifles without scopes, but made provision on their rifle to receive scopes by drilling and tapping their guns. It was up to the purchaser to add a scope if they wanted. Over the years, an owner of a Mossberg rifle may have had a number of choices to choose from. Hope this helps. Good luck. Capt. Hal

[@Coste1072]

Great video & great collection. I too have a Model 46M(b). My father bought it for me used in 1967. It is still in very good condition & shoots terrific. The onlything I've ever had to do to keep it going is change the mainspring. However I can't seem to find sling swivels for it. Do you know a place where I could find them? For the front swivel is there another part I need that goes inside the metal stock joint?

[@capthal-rs9mq]

You can try ebay. Put in Mossberg parts and see what comes up. I have bought sling swivels on that site, but be prepared to pay. You may had to out bid Some other individuals. If you don't see any at this time just keep checking back. You might also try Havlin sales on the internet. They carry a lot of Mossberg parts. You don't need any additional parts for the swivels on the metal stock joint just the swivel itself. Good luck.

[@Coste1072]

Thanks. I have been considering finding some way of adapting another swivel to my rifle. Although I prefer the originals my main reason for wanting the swivels is to use a sling for standing position shooting. If you know anyone that has done that please let me know.

I have a 46m b and a Vintage Mossberg Model M4D 4 Power Rifle Scope -3/4" tube. is there a way to sight it in ? I ask because it sites of to the side of the barrell. I also have the peep. Just wondering if you have any tips.

[@capthal-rs9mq]

I'm not sure. A scope I guess could be mounted anywhere on a gun as long as the view though the scope is seeing the target that the barrel is aimed at. You need to adjust the elevation and windage. The scope you have was made by Mossberg around 1952 and it should work on that model rifle. I wish I could be of more help. But not seeing the rifle it is hard to help. Sorry. Good luck. Capt. Hal

[@geronbryan8628]

Just bought a 51 M b. What kind of scope and mounts would have originally been on this gun?Did the 51 m b also have the rear peep sight? Love the collection and information. Thanks

[@capthal-rs9mq]

Geron I can remember if I got the scope mounts from Havlin gun sales. Com. They know a lot about mossberg rifle. As I remember this gun had no rear sight. But originally all mossberg iron sights on one kind or another. Check with Havlin, they should have sights that will fit. Or check on gunbroker.com for original. But don't be shocked by the price. I think the original sight would have been S100 or S130. Sometime they changed the sights during production. Good luck. Capt Hal

[@SLOROB55]

My dad gave me a perfect unmodified 46 in for Christmas in 1964. I think he paid $5 for it. I saved grass cutting pay and paid a gun Smith to mount a scope on it when I was 13. The back peep came off and went in my top dresser drawer. It disappeared when I went to college. And then there’s the scope mount holes. The rifle is a laser. Zeroed at 50 yards through the peep sitting at a rest I could put all 15 rounds through the x leaving a rough hole one could cover with a dime. Squirrel and crows did not stand a chance. I cut my teeth on that rifle. It ruined me for anything that wouldn’t drive tacks. Do they all shoot that sweet? Does the 151 shoot that sweet? Thanks Rob

[@capthal-rs9mq]

I own 7 Mossbergs . I believe that they all are great shooters. Just like all guns it depends on the marksmen to bring out the best in any rifle. Mossbergs were know for their excellant barrels. I love the old rifles that are made of steel and wood. Not like some of the newer guns of today with their plastic stocks. The older rifles each have their own characteristics and story to tell. Good luck.

What are you using to polish up those stocks like that? Some sort of oil? They all look so nice and shiny.

Use alcohol to clean the stocks. It helps to remove any oil and dirt. I normally don't remove the finish. I like to keep the manufacturer organial color and finish. I then use tong oil as the final coat. Normally 2 to 3 coats and lightly sand with 000 steel wool between coats. I use the bright finish tong oil. You can use a satin finish tong oil if you don't want that high gloss. Hope this helps. Capt Hal

I'm not sure. Does the stock run all the way up the barrel. There is no metal piece connecting forearm to the rest of the stock?
