Stock crack mosin safety3/13/2023 Also known as the M91/30, similar to other cavalry rifles produced after the M91, the new rifle featured a shorter barrel and the gun was sighted with the bayonet attached. In 1930, the M91 adopted changes to speed up production time and improve accuracy. Many revisions have been made to the Mosin Nagant in the years and wars to follow. Taking on the name M91, the original model was mass produced during WWI under contracts issued to New England Westinghouse and Remington. The creators of the firearm, Sergei Mosin & Leon Nagant, constructed the firearm to allow for ease of reloading and storage of multiple rounds during combat. It has made its way to the United States in mass numbers through international arms dealers after the fall of the Soviet Union in 1991. The Mosin Nagant is a Russian bolt action rifle that was first produced in 1891. ![]() Let’s review the history of the Mosin Nagant, then take a look at some upgrades that can improve the functionality of your Mosin but stays true to the gun’s history. This late 1800’s rifle is an affordable addition to any gun owner’s collection, including the first time buyer. The Mosin Nagant is a well-known military rifle that has made its ways into the hands of many hunters, collectors, and sport shooters. However, the MN is about as bulletproof as anything gets.Mosin Nagant: Improve while Maintaining Its Historic Integrity If you are shooting guns in the first place there is an element of risk. I am no expert on reloading, but I am certain most failures are caused by human error (double or excessive charge weight for a given cartridge and projectile, or use of the wrong powder) rather than a defective firearm. When reloading, you'll need to primarily make sure you are using proper load data, which may be significantly less powder weight than whatever your surplus ammo had in it. Reproofing the barrel would probably do more for you than any MPI, but I don't think you need to. Unless it has been shot enough to scrub all the rifling out of the barrel or become rusty, it should be adequate to handle properly loaded cartridges until pretty much the end of time. The barrel is then stamped or "proofed" at the factory, your MN will have a proof mark. The real test of a gun barrel is the proof test, where a cartridge is loaded to higher than normal pressure and shot through the barrel. Like stress cracks, embrittlement fracturing, etc. Back in the good old days circa 70's-80's, you could MPI all the journals and still have the thing fly apart on you anyway, more recently I think the forging process is a little cleaner and laser heat treating replacing nitriding, etc.Īnyway, my point is that is detects primarily physical defects that make it through to the surface and interrupt the magnetic flux on the surface of the metal. PS: I will let you know what I learn from my machinist as soon as I can.Īny of the magnetic dye processes like magnaflux can help find a surface fissure, but you can have a fairly significant exogenous inclusion in the steel from the forging process pass a MPI test totally undetected, and then subsequently cause a rather spectacular fatigue failure- singe you are in the automotive world, I will cite as an example a forged crankshaft. Any thoughts or facts on the matter? If so please answer this post so we can all sleep better at night not worrying that our rifles are going to explode the next time we send a round down range. I had kind of assumed that when they were imported they were examined for safety to keep the importers from being sued. ![]() He is only going to charge me $15 so it is definitely worth the money for the peace of mind. I found a machine shop that is capable of doing a magnaflux job for me and plan on having it done this coming week. The rifle holds zero perfectly and I have not seen any sign of metal fatigue in any way. I recently drilled and tapped my receiver for an ATI scope mount and I had no problem with it at all. Has anybody out there ever heard of a Mosin Nagant exploding ever? I mean at any time for any reason whatsoever. So, I decided to come right out and ask the question. I explained to him that I was a member of several forums dedicated to this rifle and that I had never heard even one story of a rifle blowing up or even fizzing up for that matter. It is a process used to check for weak spots and cracks in metal due to fatigue and in the auto world it is usually after someone runs a vehicle hot and stresses the head and block due to excessive heat. Being a mechanic I am aware of what magnafluxing is. I was kind of confused by his question at first. ![]() I was having a discussion with an old friend the other day and he asked me if I had my barrel magnafluxed. Alright, y'all, I have been talking to many people about reloading for the 7.62X54R and I keep hearing about how I need to be very careful and not blow up this old weapon we all love so much.
