Hi there FLSailor. Welcome to the forum.

Your Revelation 100 should prove to be a reliable shooter. It is vitally important to do a good cleaning. I'd completely strip the rifle and pay special attention to the bolt/firing pin which tends to get gummy over time. Once you have it cleaned up and functioning well, you can turn to the stock.

If the stock is painted brown I think I might skip some of the lighter solvents and go straight to a paint stripper of some sort (like Citristrip Gel) or whatever you can find locally. As for refinishing, there are as many products and theories as there are ways to skin a cat. If you search this forum you will find many descriptions and formulas of "this is how I did it" with beautiful results. Personally, I vary my methods depending in the type of wood I'm working with. I'm thinking a Revelation stock will be of birch rather than walnut. If so I'd use a stain or dye to color the light wood and then either rub on True Oil or spray it with clear lacquer. The lacquer will go on much more quickly but the True Oil will add some character to the finish. Both look great if done correctly. Again, use the SEARCH function at the front of the forum and you will be rewarded with an evening or two of insightful reading. I'm sure others will chime in too.

Hope you enjoy your new Mossberg and hope you discover the fascinating history behind the guns. Most all of us here have been sucked in by the allure of these beautiful and often underrated firearms. It can easily become a sickness. Trust me, many of us have fallen to the disease. Run away quickly before it is too late.

 

Of course!

This gun has some really odd problems...

I cannot get the bolt out because the receiver catch latch appears to be installed backwards:

The rear sight appears to be installed too far to the rear and sits on the receiver instead of the barrel:

A lot of what looks like rust appears to be brown paint from the stock.

 

Yep, according to the parts breakdown that receiver cap latch is indeed in backwards. If it were me I would simply take a punch and drive the pin out. Then everything should fall out. You can then reassemble the cap the way it's supposed to be., then it will work as designed.

 

Progress...

That was my thought on the solution as well, and it worked fine once I quit tapping the punch with a screw-driver handle and brought out a proper hammer :bonk:

The receiver has dove-tails, and I'll likely mount the scope from my pellet rifle on this rifle and see how it works. The scope wouldn't even stay put on the pellet rifle, so I might need to get some new rings and drill for set-screws while I'm at it.

My rear sight is most like the S-134 and S-137, though they have a split "tang" while mine is solid. I suspect it may be off a different gun. I do have the mounting holes for (I think) an S104 sight, so that could be an option.

Also, there are no mounting points for a sling, so I'll probably look into adding these when I refinish the stock.

 

I agree with Steve about the latch but I've never had one apart myself. Couldn't hurt to try getting that pin out and see what happens.

I'd expect the rear sight to be mounted in a dovetail on this model. That said, Mossberg did make two screw mounted sights like the one on your rifle. The big difference between the two was the length. May the "other" model is shorter? Is there an open dovetail in front of your sight? Is your rifle drilled and tapped for a receiver sight?

Lots of good info here: http://home.epix.net/~damguy/

 

I'd expect the rear sight to be mounted in a dovetail on this model.

One of my first Mossbergs was a 340 series, which a friend of mine had given to me. He had cut the barrel off at 10 inches, which I promptly removed and destroyed. Anyway, I found a barrel through Numrich for it. The barrel was from a Montgomery Wards Hawthorne Warrior. It had the two screw holes for the rear sight, while the original barrel was dovetailed.

 

Bought mine last year, safety was bent, one E clip missing and the firing pin was gummed up with dry oil. After a good cleanning and fixing the minor problems that little rifle had a great trigger and is pretty accurate. Because its light and compact it always seems to go out a lot more than the others. Remembering to slipping off safe after loading became muscle memory pretty quick. Wise choice and it'll be a 22 you will enjoy and yes they are worth the trouble to put a nice scope on.:t

 

All in pieces!

I've been disassembling and cleaning the rifle in sub-assemblies as I go. I've done it in this order so far:

Receiver cap and latch
Safety
Bolt
Front half of the trigger assembly
Rear half of the trigger assembly
Trigger Bracket / Ejector
Receiver and Barrel

As I cleaned each assembly I laid it out in order of re-assembly on a napkin. It *should* be a simple matter of start from the bottom napkin and work my way back up until I have a clean, lubricated, reassembled rifle.

This is my first time working on any firearm. I have a Mosin-Nagant 91/30 sitting in my room waiting for me to get the nerve to tear it apart. The little Mossberg seemed like a better place to start.

 

The S-104 aperture sight (more commonly referred to as a "No.4") is for much earlier models. Your rifle needs an S-330 aperture sight. (Don't confuse it with the similar S-331 sight).

 

Missing parts

Here is the picture I took when everything was disassembled and laid out:

Upon re-assembly I've discovered some missing pieces. With the receiver cap latch installed correctly, the receiver cap is extremely loose. The stock is all that is holding it from sliding right out. I seem to be missing the Receiver Cap Spring (#14 in the parts list).

Also, the safety no longer works correctly. It just flops around. The Click Plate (#35 in the parts list) seems to be missing. I can't think of any reason for a change in function of the safety other than I must have lost this piece, but I don't remember ever seeing it....

The scope will require some offset rings to get proper eye relief.

 

...I seem to be missing the Receiver Cap Spring (#14 in the parts list).

This will get you started.

Or you could substitute it with one from a hardware store. It just has to be stiff enough to hold that forward hook down.

That safety issue rings a bell. It seems like I had a problem with mine, but it was so long ago I don't remember what the problem was or how I fixed it.

 

The safety on these doesn't "click" into one position or the other, it just kind of slides back and forth. I thought something was wrong with mine as well, but that is the way it should be. Takes a little getting used to. Matt

 

Before disassembly, the safety worked properly. After reassembly, it literally flops around. After cocking the bolt I can tilt the barrel up and down and the safety will move forward and back.

It looks like Numrich might have both the spring and the plate :bthumb:

I need to send in the paper-work for my FFL 03 so I can get better prices on parts.

 

Suggestion; try a spring out of a value core stem for the spring in your end cap. Also is your barrel 24" long? The way your rear sight is mounted makes me wonder if your barrel has been cut and set back.

The spring is a bit small in diameter but it stays in place well enough and has enough force to do the job. Thank you for the suggestion!

Bingo! The barrel is 21" long. Why would anyone cut it down On one hand, I'm annoyed that I bought someone elses hack job. On the other hand I'm relieved that I can do anything at all to the barrel without reducing its value any more. Specifically, that front sight will likely get replaced.

The issue with the safety is still a bit of a mystery. The solution, however, was simple. I was missing an e-clip for the hammer pin (there was a crimped piece of wire as a replacement instead) so I bought 3 at the hardware store. I put new e-clips on both the trigger and hammer pins. I put an original e-clip on the saftey pin and jammed another one between the plates of the safety. This provides some extra force to make the safety "bump" engage the safety "divots".

The trigger pull has gone to hell since reassembly. It used to be very smooth, light and crisp. Now it's a bit tough, and there is almost no movement before it actually fires. Any idea what I did wrong here?

Additionally, the bolt is rather stiff where it engages the ramp. I may add a washer between the receiver and ramp where they bolt together. Hopefully this will reduce the pressure a bit. Do you have any other suggestions?

 

Weaver TO-10

I modified a weaver TO-10 adapter to mount a scope on my 640K. The TO-10's cost less then $10.00. Do a search in the mossberg forum for "Weaver TO-10".

 

I have a 340KB that is like the 321 except it is clip fed and the safety is the same without the safety actucator bar. The safety on my 340KB is held on to the safety pin by a concave spring clip like in the attached picture.

Check the screw that hold the ejector in the receiver, if it is to long it will drag the bolt If it is to long put a washer under the screw head.

Why would anyone cut down the barrel. Someone may have rechamber the barrel.

Sorry but I am not much help on the trigger, maybe one of the more experienced members can help

Have fun
