Step-by-Step Disassembly Guide

Alright, let's get into the nitty-gritty of disassembling your Mosin Nagant M91/30. Follow these steps carefully, and you'll have your rifle field-stripped in no time. Remember, safety first, so make sure your rifle is unloaded before you start.

1. Bolt Removal: The first step is to remove the bolt. Pull the bolt fully to the rear. Then, depress the trigger and continue pulling the bolt out of the receiver. You might need to wiggle it a bit, but it should come out with a little coaxing. With the bolt removed, you can now proceed to disassemble it further if needed.
2. Magazine Disassembly: Next, let's tackle the magazine. Locate the magazine release latch at the front of the trigger guard. Press the latch forward, and the magazine floorplate should slide forward and off. Be careful, as the magazine spring is under tension and could launch the floorplate if you're not careful. Once the floorplate is removed, you can take out the magazine spring and follower. Now you have all of the components of the magazine disassembled.
3. Handguard and Upper Heat Shield Removal: This part can be a little tricky, but don't worry, you'll get it. The handguard is held in place by two spring clips. Gently pry these clips open using a flat-head screwdriver or your fingers. Once the clips are open, you should be able to slide the handguard forward and off the barrel. Be careful not to scratch the barrel or the handguard during this process. Underneath the handguard, you'll find the upper heat shield. This is usually held in place by friction. Gently wiggle it until it comes loose. These steps will allow you to clean and inspect the barrel and gas tube.
4. Stock Removal: The final step is to remove the barreled action from the stock. Locate the two action screws on the underside of the stock, one in front of the trigger guard and one behind the magazine. Use a flat-head screwdriver to unscrew these screws. Once the screws are removed, you should be able to lift the barreled action out of the stock. Be careful not to force anything, and make sure everything is aligned properly. With the barreled action removed, you can now clean and inspect the stock and all of the internal components.

Following these steps should give you a completely field-stripped Mosin Nagant M91/30. Remember to take your time and be careful, and always refer to a qualified gunsmith if you're unsure about any of the steps. With practice, you'll be able to disassemble and reassemble your Mosin Nagant with ease. So go ahead, give it a try, and enjoy the satisfaction of knowing your rifle inside and out.

Cleaning and Maintenance Tips

Now that you've got your Mosin Nagant M91/30 all taken apart, it's time to give it a good cleaning and make sure everything's in tip-top shape. Regular cleaning and maintenance are essential for keeping your rifle functioning smoothly and accurately. Plus, it's a great way to get to know your rifle even better. Start by cleaning the barrel. Use a good quality bore cleaner and a cleaning rod with a brush attachment to scrub the inside of the barrel. Run the brush through the barrel several times, then use clean patches to wipe away any residue. Repeat this process until the patches come out clean. This will remove any fouling or buildup that can affect accuracy. Pay attention to the crown of the barrel, as this is where the bullet exits and any damage or imperfections can have a significant impact on performance.

Next, clean the bolt and receiver. Use a solvent to remove any dirt, grime, or old lubricant from these parts. Pay special attention to the bolt face, as this is where the cartridge sits and any buildup can cause malfunctions. Use a brush or a pick to clean out any hard-to-reach areas. Once everything is clean, apply a light coat of oil to all metal surfaces. This will help prevent rust and corrosion. Be sure to wipe off any excess oil, as too much can attract dirt and grime. Lubricate the moving parts of the bolt and trigger mechanism. Use a high-quality gun oil or grease to keep these parts moving smoothly. Pay attention to the contact points and any areas where there is friction. A little bit of lubrication can go a long way in improving the reliability and performance of your rifle.

Inspect all of the parts for wear and tear. Look for any cracks, chips, or signs of damage. Pay special attention to the springs, as these can weaken over time. If you notice any problems, replace the affected parts as soon as possible. It's always better to address issues before they cause a malfunction. Finally, reassemble your Mosin Nagant following the steps in reverse order. Be careful not to over-tighten any screws or bolts, as this can damage the threads. Once everything is back together, function-check your rifle to make sure everything is working properly. Cycle the bolt, pull the trigger, and make sure the safety is engaged. If you notice any problems, disassemble the rifle and check your work. With regular cleaning and maintenance, your Mosin Nagant M91/30 will provide you with years of reliable service. So take care of your rifle, and it will take care of you.

Reassembly Tips and Tricks

Okay, you've taken your Mosin Nagant M91/30 apart, cleaned it, and now it's time to put it all back together. Reassembly can sometimes be a bit trickier than disassembly, so here are a few tips and tricks to help you get it done right. First, make sure you have a clear workspace. Lay out all of the parts in an organized manner so you can easily find them. Refer to the disassembly instructions as needed to refresh your memory on the proper order of reassembly. Start with the barreled action and stock. Carefully lower the barreled action into the stock, making sure everything is aligned properly. Replace the action screws and tighten them securely, but not too tight. You don't want to strip the threads or crack the stock. Next, reassemble the magazine. Place the magazine spring and follower into the magazine body, then slide the floorplate back into place until it clicks into the latch. Make sure the magazine spring is properly seated and the follower moves freely.

Now, let's move on to the handguard and upper heat shield. Slide the upper heat shield back into place, making sure it is properly seated. Then, slide the handguard back onto the barrel, aligning it with the spring clips. Snap the spring clips back into place to secure the handguard. This part can be a little fiddly, so take your time and be patient. Finally, reassemble the bolt. This can be the trickiest part of the whole process, so pay close attention. Make sure the bolt head is properly aligned with the bolt body, and then insert the firing pin assembly. Compress the firing pin spring and rotate the cocking piece until it locks into place. Then, insert the bolt back into the receiver, making sure it is properly seated. Cycle the bolt a few times to make sure everything is working smoothly. Double-check all of the parts to make sure they are properly installed and secured. Look for any loose screws, misaligned parts, or other potential problems. If you notice anything amiss, disassemble the rifle and check your work. With these tips and tricks, you should be able to reassemble your Mosin Nagant M91/30 with ease. Just remember to take your time, be patient, and pay attention to detail. And if you're ever unsure about anything, don't hesitate to consult a qualified gunsmith.

Troubleshooting Common Issues

Even with the best care and maintenance, you might run into some issues with your Mosin Nagant M91/30 from time to time. Here are a few common problems and how to troubleshoot them. First, let's talk about sticky bolt. This is a common issue with Mosin Nagants, especially those that haven't been cleaned or lubricated properly. The bolt feels difficult to open or close, and it can be frustrating to deal with. The most common cause of a sticky bolt is a dirty chamber. Over time, carbon fouling and residue can build up in the chamber, making it difficult for the cartridge to extract properly. To fix this, thoroughly clean the chamber with a good quality bore cleaner and a chamber brush. Make sure to remove all of the fouling and residue, and then apply a light coat of oil to the chamber walls. Another possible cause of a sticky bolt is a dry or improperly lubricated bolt. Make sure to lubricate all of the moving parts of the bolt with a high-quality gun oil or grease. Pay special attention to the bolt lugs, the cocking piece, and the firing pin assembly. A little bit of lubrication can go a long way in improving the smoothness of the bolt action.

Next up is failure to extract. This is when the cartridge case gets stuck in the chamber after firing. This can be caused by a dirty chamber, a worn extractor, or a damaged rim on the cartridge case. Start by cleaning the chamber thoroughly, as described above. If that doesn't fix the problem, inspect the extractor for wear or damage. The extractor is a small claw-like part that grips the rim of the cartridge case and pulls it out of the chamber. If the extractor is worn or broken, it will need to be replaced. Also, check the rim of the cartridge case for damage. If the rim is bent or deformed, it may not be properly gripped by the extractor. Finally, let's address failure to fire. This is when the trigger is pulled, but the rifle doesn't fire. This can be caused by a weak firing pin spring, a dirty firing pin channel, or a faulty cartridge. Start by inspecting the firing pin spring for wear or damage. If the spring is weak, it may not be able to generate enough force to ignite the primer. If the spring looks okay, clean the firing pin channel with a good quality solvent and a small brush. Make sure to remove any dirt, grime, or old lubricant that may be obstructing the firing pin. If the problem persists, try using a different brand of ammunition. It's possible that the cartridge is faulty or that the primer is not sensitive enough. By troubleshooting these common issues, you can keep your Mosin Nagant M91/30 running smoothly and reliably for years to come.
