Taking stock…

20160116_103059ATI makes a very nice looking monte carlo stock for the Mosin. I picked one up at Bartons’. It was 107$, not too shabby a price. It comes with a cheek pad that has a peel-n-stick backing. You just peel the back off and install it on the comb.

I like the look of the stock. After all is done, the rifle shoulders beautifully. It feels great. But… the fitting process took some doing. 20160116_103236As you can see in the pictures, I really had to get in there, rip-tear-and-pull-hair. I used a file, sandpaper and an angle grinder to work the plastic into good shape. I really wish I had a dremel…

The barrel channel isn’t straight or wide enough.20160116_103248 I had to open it up by about a 1/4″ just to float the barrel. The action sat up on the stock so the action screws cannot even make contact with their threads.

In the top picture I show with the screwdriver a particular spot inside the stock. That spot is of great importance. If that spot isn’t milled out to the proper depth, the magazine interrupter, which is attached to the ejector, will not function. If that part of the stock isn’t inletted properly the interrupter impedes loading the magazine. A single-shot rifle is pretty useless in my view. 20160116_103157

All this to say, I am disappointed that this “drop-in ready stock” isn’t anywhere near drop-in ready. I am doing a second Mosin, and all the same problems occur. I can understand some work being required, but this does seem excessive. For 107$, I expect better quality.

Once the milling is all done, I would recommend bedding the action. Adding epoxy to the receiver lug cut-out and tang slot are a good idea. There is a bit of room in there that can be filled. 20160116_103258 20160116_103305

The idea with bedding the action is that there is some room in those cut-outs. As the rifle recoils, some movement in the action will be expected. This leads to diminished precision in shot placement.

We will examine the process of epoxy bedding in a later post.

 

 

American gun-control debates aren’t helping us at all

thThis flag says it all. Stay away, keep off! I know my rights, and they SHALL NOT BE INFRINGED. After all, the 2nd Amendment is in the Bill of Rights, right?

Slow down turbo. Lets consider together the impact of American gun debates on our Canadian conversation. The American 2nd Amendment is a glorious part of their Bill of Rights. I am in hearty accord with it, and Amen. However, I am no American. I am a Canadian.

One of the first things the opponents of firearm-freedom in my country do is throw this in my face. “You aren’t American, this isn’t America, you don’t have the Right to Own a firearm. It is a Privilege. And it is one the government has a right to take away at any time.”

This kind of facile argument is very frustrating to deal with, as there is a grain of truth to it. I am not American, and the American Constitution and Bill of Rights have no authority in Canada. But is that all there is to this? Are Americans the only men in the history of the world who have a right to own and bear firearms? Are they unique among men?

I think not. In a future post I hope to go into the American Constitution and the context surrounding the debates and men that formed the Bill of Rights. For now, we shall leave them by the way and move forward to sketch our program.

There have been several types of responses in the Canadian gun world to the typical anti-gun rhetoric above. One method has been to grant the premise that a Right does not exist where it is not enumerated in law, and then try to amend the situation by getting laws passed or struck. This method is fine, but the premise is flawed. More on this will follow in subsequent posts.

Another response has been to find a means of making Rights universal to Nature. If all men everywhere have universal and natural, rights… and property is one of them, then all Canadians have a natural right to arms. The logic of this is fine. Unfortunately, the leftists do not agree with the premise, and I partly agree with them.

So then, we are left in a dilemma. We know that owning guns and enjoying their use cannot be immoral. Somehow we know this, and yet we must make clear what we mean and do not mean. Our task is to form our thoughts, to bend our rational powers toward the effective communication of what we believe.

If Human Rights are so arbitrary as to require ratification by law, then we know they do not suffice. What if the ownership were not a Right? What if it were a Duty?

I aim to argue that the ownership and use of firearms, for defence in particular, is a DUTY of every man.

Trigger Happy

As we go through each component of our rifle, we find little things can be improved with little or no effort. The trigger assembly in a Mosin Nagant is very simple. Some people prefer the original, unworked trigger in a milsurp gun. I guess a completely “authentic” trigger is part of the experience for purists. As is obvious, we are modernizing and modifying our milsurp. Anything that I can do to improve it, I will. Mosin triggers are not nice. Late WWII productions are particularly rough.

The first thing to do is to remove the trigger assembly from the action.20160116_103418

Use a flat bladed screw driver to remove the screw as shown. This screw holds the trigger spring and bolt stop into the rear of the receiver. 20160116_103441

 

Once this is removed, remove the trigger hinge pin. I found this came out pretty easily, but there is a lot of variation between rifles. Some pins will require the use of a punch. I used a ball-point pen.20160116_103557

 

 

This is what the parts look like when removed.20160116_103629

 

Be sure not to lose anything! If you do lose something, I have found that these parts are usually available online. That said, losing things is aggravating. If you can help it, don’t.

Next we need to inspect the mating face of the bolt stop. My apologies for the fuzzy picture. Nonetheless, it can be seen where I filed the surfaces down. 20160116_103832 The front and top needed to be shaved by just a hair. One thing many Mosin triggers share in common is that the bolt stop and the cocking piece do not mate to each other in a square manner. This directly causes the rough trigger. One method of determining if your Mosin has this problem is to cock the rifle and then take up all the trigger slack. Watch the cocking piece very carefully as you take up the slack. With an unadjusted trigger you will see the cocking piece slowly creep upward as you continue the trigger pull.

I used a sharpie to mark the mating surfaces on the cocking piece and bolt stop, then cycled the action several times and dryfired the weapon. Then I disassembled everything again, and inspected the cocking piece and bolt stop. Everywhere the ink had rubbed off shows where the surfaces made contact.

Then I took a small file and some 600-grit sandpaper and filed the mating surface square. Apply very little pressure. You do not want to remove too much material. Then I sanded the surfaces to a shine. You can see how the bolt stop and cocking piece go together below. In the second picture I inverted the bolt so it can be seen clearly.

Reassemble the rifle and dry fire it to see if the improvement is sufficient. Repeat the process as needed, but remember not to take off too much material.

There is a test that you can run to see if too much material has been removed. First, reassemble the trigger assembly. Do not put the barrel and receiver back into the stock. Holding the rifle by the barrel with the muzzle up, firmly strike down onto the floor or some other wooden surface. If when the tang strikes the floor, the gun fires, you have removed too much material.

Next we look at the barrel, and how to shorten it…

Mosin Nagant Tear-Down

20160116_102257The very first thing to do in our gun build is to take it down. As we go along, I will attempt to illustrate each step with a picture. Mosins are easy to take down, so it will be easy to learn this process.

Before we get to the process itself, please remember that you will have to strip the cosmoline the first time you take it apart. Cosmoline is a preservative gel-like substance that was used to preserve rifles through long storage. After the gun is broken into its component parts, rinse everything in hot soapy water. Dish soap like Sunlight works well.

As can be seen in these photos, I have already discarded the original wooden stock. The process shown below is identical for taking apart a rifle in that configuration, with the only difference being that you must take off the barrel bands as well.

Lets get to it.

Step 1) Remove the bolt. Draw the bolt to the rear of the action, as shown above. Depress the trigger, and then continue to draw the bolt out.

20160116_102450 20160116_102515Step 2) Remove the action screws. There is one in the rear of the tang, behind the action. The second screw is at the front of the magazine. Remove with a flat-bladed screwdriver.

 

 

 

 

Step 3) Remove the magazine and action from stock. Pull out the magazine first, as shown.20160116_102830

 

 

 

Then the receiver and barrel assembly.20160116_103034 I usually insert my forefinger into the rear of the action and lift up. This seems to be the least abusive way to get everything out.

 

 

Now the rifle is apart, and for a thorough cleaning, nothing more is required.

 

 

The Babushka Gets a Facelift… and some new hardware.

20151010_135948Our story begins in 1889. This was the year that the Russian Czar put an order out for a rifle that would be of “reduced caliber” and using “smokeless powder”. At that time the Imperial Army used the Berdan Rifle. The Mosin-Nagant was the rifle adopted in 1891.

Its cartridge was the 7.62x54R. The (R) designates that it is a rimmed cartridge, like the .303 British or the 8mm Mauser. In the late 19th century rimmed cartridges were all the rage. Of all the late 19th century cartridges, only the 7.62x54R is still in regular military use.

As the British, Italians, Germans, Austrians and Japanese had all been adopting bolt-action small-bore, magazine fed rifles in the decade prior, it was felt Russia ought have one too. The final design was an unwilling collaboration between the Russian officer Sergei Ivanovich Mosin and the Belgian inventor, Leon Nagant.

From a design perspective, the rifle borrowed features from most of the main battle rifles of the day. What the Russians got was a slightly uglier mash-up of the Mauser, Mannlicher, Enfield and Carcano. Considering that it was for use by the Russian Army, not famed for professionalism at the time, this rifle turned out to be fantastic.

Imperial soldiers (and their later Soviet counterparts) carried this rifle into many of the main wars of the early 20th century. It developed a reputation for being impervious to most damage. In the right hands it was even a well-considered sniper platform. A Finn named Simo Hayha recorded 505 confirmed kills on one of these rifles during the Finn-Soviet Winter War of 1939-40. He used the standard iron sights. Vassili Zaitsev and Lyudmila Pavlichenko are two of the more well-known Soviet snipers who used this rifle as well.

Some folks in the blogosphere like to hack this rifle on account of accuracy. They clearly weren’t shot by Hayha. Just sayin.

I bought this rifle for 150$ in a local gun shop, and have since made some changes. 20160116_102124And thus we begin! In this series of posts we will look at each step in the process, and comment on each step. Then we will shoot and evaluate our new Mosin. Let the fun begin…

Chop job

20160116_102237As most of you may know, a standard m91 has a 28 inch barrel. That is ridiculous. There are several reasons to cut a Mosin barrel down.

First, a 28″ barrel looks funny on a Monte Carlo stock. A barrel that long is also difficult to manoeuver in dense brush, which is where most of my hunting spots are. Third, longer barrels have more “whip” than a shorter, thicker, profiled barrel.

Lets look at that last point in particular.

When a bullet is fired from its’ cartridge through a barrel several things are happening. We call this “internal ballistics”.

The basic idea is that when the projectile leaves the cartridge mouth it passes into the barrel. The barrel has spiraled grooves cut in it, called “rifling”. These grooves grab the bullet and impart a spin to it, so that when it leaves the muzzle, the bullet is spinning, like a football. This spin aids accuracy. While the bullet is still travelling through the barrel, several forces are acting on it. There is the pressure wave of the explosion in the casing, which pushes the bullet forward. Friction is created by means of the interaction between bullet and the rifling, which gives spin. Air resistance is also present, as the volume of air in the barrel must be displaced, but this is really minimal.

The “whip” in a barrel is a result of the friction between the bullet and the rifling. We know that every action has an equal and opposite reaction. As the bullet spins, the barrel will move in an opposing manner.  To be sure, the barrel posses more mass than the bullet and will not move as much as the projectile, but it moves nonetheless. After the bullet leaves the muzzle the barrel will return to its original position. A shorter, thicker barrel should whip less that a longer one. With less whip comes a higher degree of probability that the barrel will more consistently return to its true position after firing.

All this to say, a shorter, thicker barrel ought to be more accurate, especially over a longer shooting session.

On account of these reasons I shortened my Mosin barrel.

Some other folks are better equipped than I in regards to tooling and such, so I have had to improvise somewhat. Before ya’ll start throwing the blog-o-bombs, hear me out. I cut my barrel down to 22″ with my angle grinder. After using my files and elbow grease, I switched to sandpaper and buffed the muzzle up.

As I do not have a crowning tool, I made use of my drill, a screw, and toothpaste. It makes a decent crown. A crown does not need to be much deeper than the bottom of the grooves. This method works pretty well, and for pennies on the dollar.

20160116_102539Insert the screw into the drill chuck, with the head sticking out. Put a dab of toothpaste on the screw head, and mill out the crown. Toothpaste acts as a grit paste. Move the drill in a circular motion so as not to wear any part of the crown more than another. It is important to get as even a bevel as possible.

We will cover accuracy and results in the final installment at the end of this series. Suffice it to say, the accuracy of this rifle improved over the course of this build. It doesn’t take expensive tools to do a job, nor to do it well. Time, some expertise, and a good idea of the end goal are worth just as much.

In the next post we will examine the drilling, tapping and mounting of the scope rail…
