Common Mossberg 835 Problems And Their Solutions

1. Failure to Feed

First, what exactly causes shells to get stuck on their journey from magazine to barrel? Well partner, any obstruction along the feeding ramp is suspect numero uno. Could be buildup of dirt, residue, or even damage blocking things up.

Secondly, we gotta ask – are your shells the right size and type for the chamber? Trying to feed 3 1/2″ mags into a 3″ chamber just ain’t gonna work, like tryin’ to saddle a mouse. Make sure your rounds match the specs.

Alright, with the problem narrowed down, here’s a step-by-step approach to clearing the jam:

First, safety check it – unload the mag tube and chamber. Next, field strips it down and thoroughly clean the action rails and shell ramps. Inspect closely for any burrs or dings blocking the path. Lightly polish out any imperfections. Check the carrier and action bars for smooth movement too. A drop of lube can help.

Once it’s all cleaned up nice as you please, reassemble and try some fresh shells. Make sure to use the recommended length for that barrel.

Keep everything squeaky clean and properly maintained – your 835 will glide shells in slick as spit on a watermelon seed when all is said and done. Happy shooting!

2. Failure To Eject

This common pump-action headache can definitely be remedied with a bit of expertise.

First, what is occurring when a fired shell fails to eject? In short, the empty cartridge remains stuck in the chamber after the shot rather than being expelled as intended. There are two primary culprits:

A weakened or damaged ejector spring is unable to fully clear the chamber. Inspection will reveal poor tension or cracks. Replacement with an OEM spring will typically resolve this.

The buildup of fouling around the chamber and ejection port, impeding the shell’s exit. Thorough cleaning and light lubrication addresses this issue.

To detail the repair process:

First, ensure the shotgun is unloaded and pointed in a safe direction. Field strip the firearm and inspect the chamber, ejector, spring and general fouling levels.

If heavy buildup is present, meticulously clean the chamber and action with solvent and an appropriate bore brush.

Visually inspect the ejector and spring – any cracks or damage will necessitate replacement parts. An OEM spring is recommended for reliability.

Lightly lubricate the ejector, spring, and chamber when reassembling. Snap caps can be used to test functions. The firearm should now reliably eject spent shells. Maintain cleanliness going forward.

3. Accuracy

Firstly, what factors influence a shotgun’s accuracy? Well, proper ammunition matching is paramount. Using shells that don’t align with the chamber spec can lead to erratic performance. Always use the gauge and length recommended by the manufacturer.

The condition of the barrel and choke is also critical. Excessive fouling buildup inside the bore will negatively affect shot consistency. Similarly, dents or damage to the muzzle or choke threads can interfere with proper patterning.

Finally, component fit and lockup tightness impact precision. If the forend, action bars or barrel lug exhibit excessive play, the firearm won’t maintain optimal alignment when firing.

Here are systematic steps to improve that clumsy accuracy:

Start with a thorough deep cleaning using a quality bore solvent and brush to remove all fouling. Inspect for barrel dents or damage. Check chamber and muzzle threading as well.

Field strip the shotgun and ensure tight, smooth functioning of the forend, action bars, and moving parts. Tighten any loose screws or fittings.

Reassemble everything tightly and lubricate lightly. Test with various slugs and shotshells to analyze performance. Switch chokes and try different ammunition brands to isolate the variables.

4. Magazine Issue

Is your magazine failing to feed rounds properly? Experiencing jams mid-cycle? Showing signs of corrosion or mechanical wear? Don’t worry – with a few simple tools and tips, you can get your magazine running smoothly again.”

Feeding Issues:

A bent or dented magazine body can cause rounds to snag internals instead of feeding upwards. Similarly, a weakened magazine spring may fail to push rounds properly.

First, inspect magazine body for any deformations. Use fine grit sandpaper to smooth out any protruding dents gently. Replace spring if worn out. Test cycle magazine without rounds to check for free movement.

Extraction Problems:

If empty cases fail to eject fully, the extractor claw may be worn or gummed up with residue.

Detail strip and thoroughly clean extractor. Inspect for signs of damage or cracks. Use solvent and brush to remove built-up carbon deposits around the extractor. Replace if worn. Lightly lubricate extractor parts during reassembly.


Exposure to moisture or humidity can cause corrosion on the magazine body, spring and follower.

Disassemble the magazine fully and clean all parts to remove rust/tarnish. Use solvent, bronze brush, and/or very fine grit sandpaper as needed. Prevent future corrosion with light gun oil or protectant.

Let’s keep our magazines in top shape – inspect often, clean routinely, and replace components at the first sign of damage. With some DIY care, you’ll have a magazine that runs like new for years of reliable service.

5. Misfire 

“Pulling the trigger and hearing just a disappointing ‘click’? Don’t let a misfire kill your range day. With some simple troubleshooting, you can get your firearm back to firing flawlessly.”

Faulty Ammunition:

Outdated, damaged or improperly stored ammo is a prime suspect. Inspect rounds for dents, corrosion or other defects before loading. Discard any suspicious ammunition.

Stuck Firing Pin:

Residue buildup around the firing pin can impede movement, preventing strong contact with primer. Detail strip and clean firing pin channel and pin thoroughly to restore function.

Weak/Worn Hammer Spring:

The hammer spring drives the firing pin into the primer. Weakness through age or damage can cause light primer strikes and misfires. Replace worn-out springs to restore proper force.

Improperly Installed Primer:

If manually reloading ammunition, ensure primer is properly seated. A loose or incorrectly installed primer won’t detonate ammunition. Re-seat primer per manufacturer instructions.

Faulty Fire Control Components:

Issues with the trigger, disconnect, sear or other fire control parts can prevent proper firing function. Thoroughly inspect all components, replace if damaged.

Misfires are frustrating but easily remedied. Inspecting ammunition, cleaning firing train parts, and replacing damaged components get you back shooting reliably. Don’t settle for “click” – implement this guidance to restore “bang!”

6. Jamming Problems

Some users have reported jamming issues with the Mossberg 835. Jamming occurs when spent shells fail to eject properly, rendering the gun inoperable.

This can be frustrating and potentially dangerous in self-defense or during hunting. So, what could be causing these problems?

One possible cause is improper ammunition use. The Mossberg 835 is designed for 12-gauge shells ranging from 2 ¾ to 3 ½ inches. Using larger or shorter shells can cause jams. Always double-check the ammunition before loading.

Another factor is a dirty or poorly maintained gun. Shotguns, like any firearm, require regular cleaning and maintenance. Built-up residue can cause sluggish action and jams. Clean your Mossberg 835 after each use.

A worn or damaged magazine tube can also lead to jams. Regularly inspect and replace any damaged parts.

Lastly, user error can also be a factor. Improper handling and loading can cause misalignment and jams. Follow proper procedures for your Mossberg 835.

7. Trigger Stuck Issue

One of the main causes of this issue is debris or residue buildup in the trigger assembly. This can occur over time from regular use and inadequate cleaning.

The good news is that this problem can be easily fixed with some simple steps.

Always ensure proper cleaning of your Mossberg 835 after each use. Disassemble the trigger assembly and remove any dirt, debris, or oil buildup.

Use a cleaning solvent and firearm-specific lubricant for proper maintenance.

If the trigger still gets stuck after cleaning, it may be due to worn or damaged components.

In this case, it’s best to have your shotgun inspected and potentially replace parts by a certified gunsmith. Neglecting these repairs can lead to further malfunctions and safety hazards.

Another factor that can contribute to trigger sticking is the type of ammunition used. Some users have reported this issue with certain shells, such as reloads or low-quality rounds. Always use high-quality ammunition suitable for your firearm.

8. Bolt Assembly Problems

One common issue is the bolt not locking properly when closing the action. This can be caused by factors like dirt obstructing movement or misalignment.

To resolve this, thoroughly clean and inspect the bolt assembly, ensuring proper lubrication. Adjusting or replacing the extractor may also help.

Another problem reported by Mossberg 835 users is difficulty in disassembling and reassembling the bolt assembly. This can be due to parts getting stuck or not fitting smoothly. Refer to the instruction manual for proper steps, or seek assistance from a gunsmith if needed.

Improper handling or abuse can damage the bolt assembly, leading to malfunctions. Always handle and store the firearm with care to avoid issues.
