I just bought a 590a1 today. My first gun, ever. Immediately when I got it home I took it apart, looked at all the pieces spread out on my table, and started to panic because I had no goddamn clue how to put it back together. This video saved me. I just hope I did it right, otherwise it's going to blow up in my face when I take it to the range tomorrow.

7 years late but oh my god thank you for this video people dont know how to make a detailed video like you ive been watching vids on this gun for 3h and just now got it back together after cleaning it thanks to you literally just being thorough with your instructions basically i couldnt get the action bars to go back in place for 3h going back and looking at videos because none of them simply explained the little lug on the end of the flat piece underneath them was supposed to fit in the bolt. now i got it back together and working great after your video thank you soooo much. 3 HOURS!!!!😭😭😭

appreciate you bro, just got one today. you just helped someone 7 years later.

Thanks for the video. The reassembly is definitely a "trust in the process" sort of deal. Everything feels loose. Some things are done by feel, some things feel a little loose until you snap in the trigger. This definitely helped. My shotgun was running real bad, jamming up and the safety wasnt really working. Its smooth as butter now

my 590A1 came today. thanks for this video sir, very helpful!

Thank you! This was the perfect speed and made it super easy for breaking down and putting back together my shotgun. Greatly appreciated!

Old video but it sure saved my skin. I was able to figure out how to take the thing apart when I was changing the fore end stock but putting it back together was frustrating me to no end but your video helped me a ton, though I still have to fight the action bars, they kept getting in the way of getting the trigger unit in. Thank you much for making this video.

I was having a heck of a time getting mine back together for the first time. Your video is gold! You explained and demonstrated everything perfectly. Thank you!

Thanks for this. Just broke down and cleaned a new to me lightly used 590a1 I found at a local shop. $495. Serial number shows it was made in 2015-16 range. 20 inch 8+1. Maybe could have got them down some in price or found cheaper somewhere else, but felt it was fair given the market and they are good people. Your video helped a ton.

Just bought the exact same 590 with Magpul stock as well. Super helpful to help us care for our Mossberg 590a1. Thank you Sir!! Great job!!

Very helpful ! I have a 590A1 on the way. Yes I read the manual but I like watching it done much more.

Thanks for the video. It was the first one I watched after purchasing. The only bit I would add (and it's not on ANY of the maintenance videos) is showing how the bolt tray fits into the bolt mechanism after they are removed. Remember, this is something you cannot directly see (once the tray is out, there are a couple places the tray latch could go). Otherwise, I'm glad this was the first demo seen - very valuable!

Exactly what I needed.. great job very helpful.

Nice video Dude!! It's been a while since I've done a total Field Strip of my 590A1 so I just wanted to freshen up my memory and you video did it for me. Thanks for taking the time to film, edit and upload this video. May I offer a tip that works for me regarding the Shell Stop and Shell Interrupter? As these 2 items quite often cause frustration with people, as they fall out with the slightest movement of the shotgun, what I do is I add a dab of grease behind each one of them and the grease acts like a "paste" and it helps to hold both of these pieces to their locations inside the Receiver. It helps me, so I wanted to add that in for other folks whose patience maybe wearing thin when these pieces keep falling out of their tracks in the Receiver. Ok, that's all. Thanks Again!!!

EXCELLENT!!! What a great Step by Step instruction to field strip and assemble a 590A1!!! PERFECT!!! Thank you for taking the time to do this video!! :)

i don't mind not knowing the actual names of the pieces I'm a visual learner and you did a good job of describing everything.

Excellent video, Nolan. I just bought a 590 A1 today and this is so helpful! Thanks a lot.

Wow, thanks for the video. I've always owned an 870 and I am very familiar with them. I recently purchased a 590a1 and really like it but as with all my guns, I clean them prior to shooting and afterwards. One thing I quickly discovered is that the 590 DOES NOT disassemble like an 870, to the point of being very frustrating (trigger assembly must be removed before the "guts" can come out) . Your video was very, very helpful. Thanks.

Thank you so much , I’m just about to get my 590 mariner and it’s a really great video you’ve made .

Thanks for that, helped me installing the 14” barrel conversion kit on my 590A1

I have just purchased a 590A1 shotgun and am waiting for it to be shipped. Your presentation was both excellent, and helpful. Thank you.

Good video. My first time disassembling, cleaning, lubricating and reassembling. This video was super helpful.

Great video. It might be helpful to explain that once you reinstall the slide bolt, you have to slide everything forward "together" before reinstalling the action bars. I didn't do this during my reassemble and the slide started to catch. It wasn't until I watched the video again that I realized you were doing it on the video. This video jumps (5:38-5:40) and you don't see the full cycle. Got it all worked out though! Terrific video and I love this firearm!

Great Job, Nolan. You have a very pleasant and easy to follow manner - thank you.

Excellent video! Helped me to disassemble my 590A1 & install the Magpul furniture

Great video. Helped me with my safety install.

Thanks for the reminder of how to take this thing apart.

You did a great job of explaining how these went back together, along with excellent video. A+++ Thanks a lot!

great job on break down of the mossberg590a1. I have a mossberg 500 I purchased in1979 I think. I was about 17 or 18.i think ..,forearm & butt stock its all wood . with heat shield. I nver really broke it down this video helped.

Took mine apart for the first time today. The video really helped.

Thanks from Crete , Greece 🇬🇷 !!

Excellent video and instructions! Thanks.

Perfectly explained! Thank for the awesome video. 😎

They are called shell stopper and shell interrupter. The shell stopper is on the left side of the receiver and it keeps the next shell from popping out. The shell interrupter, on the right side, keeps the second shell from popping out when the shell stopper is deactivated by the action slide bar on the left. The shell interrupter is manipulated by the bolt slide as is the elevator.

Nice video, and probably the best (with good lighting, and quality camera) Mossberg 590a1 disassemble/re-assemble video on KZfaq I’ve seen. 🇺🇸

Thanks. Great video. I followed this when changing my forend.

Great video Nolan. I couldn't sort it out based on the Brownells video, yours does a much better job explaining especially about how the bolt assembly needs to be lined up with the action. Thank you.

I just bought the 590A1 Retrograde and took it apart to clean it. I came to watch this video because I couldn’t get the trigger group to fit back into the gun. This was a great video however it didn’t help with my issue. Ended up having to hold those 2 bars to the sides with a lot of pressure and the trigger group finally slipped in. After being an 870 man for 30 years, I must say this thing is a PITA to tear down compared to my 870. This 590A1 is definitely growing on me though. I don’t know that it will replace the 870 as my favorite gun but I definitely don’t regret getting raped for it.

Excellent instruction video. I'm getting my Mossberg 590 SPX soon after getting my gun license in the mail. Can't wait....😁

Very well done. Thanks man!

Excellent demonstration. Thank you for sharing.

Great vid. As others mentioned, I am also a visual learner and your video did exactly what is was intended to do. Good job. BTW, my 590a1 is on order.

Thanks. I ordered mine and get it in a week, going to be using this education later 👍

Excellent video.... Thank you for sharing!!👍😎👍

Awesome to see this and awesome to see someone with a +2 like mine 👍🏾🔥

Great job! Thanks, keep up the good work!

Probably one of the best videos out on this subject picking my 590a1 up today, interested in seeing what ammo you put through yours, thanks for video.

"Right inside there you have this piece." Lol

New to shotguns. This was great! Thanks!

Excellent video ! Just what I was looking for. Thanks for doing this :)

Found you again on something I needed to learn 👍

Thanks man, good video going to use it as a guide to clean mine.

Just used vid to take down my first shotgun, Mossberg Shockwave 590S. Time saver 👍🏻

Thank you partner! Great video! My grey magpul forend is slightly tight when pumping cuz it hits the heat shield on my 590 persuader. I’m waiting on the Allen key set to take it off. Don’t have that one key anywhere in my house lol. Cheers

Nice and simple! The way a good firearm should be!😁

Thank you, great video.

Thank you! Nice Job.

Nolan, I want to thank you for the video on this gun. I owned a 16g sawed off handmade pistol grip. (Beautiful Gun) My Grandfather modified, and gave it to me. I had to use it in a home invasion/assault self- defense. Det/pd took it, and said it would be melted down. I never came across another shotgun worthy of my attention until the M590A1. I have done a ton of research 0n the gun WoW I will own this gun !! I never thought of a pump action till this one. Thank you again, and I look forward to more videos. I would love to see more info on the Truglo on the 590. Lori

excellent vid and nice visuals, whenever I get a new firearm the first step is always learn the takedown, cleaning & lube, and reassembly of your firearm. (read your firearm manual too!)

Thanks my dude. Big help.

Thanks this video was very helpful. 🙏

Very helpful!!! Thank you!

Thanks for the very good video you made.

Your video really helped me out bro!

I'd Never broken one down before and I watched your video when I took my 500 down for cleaning. I couldn't figure out why I couldn't get the bolt carrier piece back in there all the way after an hour of struggling with it I thought maybe the elevator isn't down far enough so I pushed it down and the carrier dropped into place and then I finished reassembly.

I got to 3:55 before I realized you were not going to remove the magazine tube. That is what I came here for.

Great video! Your channel is informative and well done. Just subscribed!

Thanks for this video

Awesomesauce! Thanks for sharing

Thank you man!

TY my scatteer likes you b/c I made few mistakes for the stripping of this weapon. ALso the magpul stock on mine I have to loosen it and then the trigger group can be pulled

Very helpful!

Great video!

Thanks Nolan!

Thank u brother getting this gun my next paycheck my house was robbed tonight thank God nobody was home

Well done my friend ✨🙏✨

Excellent!

Thanks for the video...

thanku, that was help for me:)

590 mariner stainless castle nut will NOT come loose. Any suggestions? Destroyed the plastic Magpul wrench right off the bat. I put a small piece of angle in a vise still nothing. It's twisting the whole forend. Just trying to put a Magpul foregrip on. This gun is from the early 90's. Good vid by the way thanks!

Who makes that brightly colored follower? I wanted a bright one as an obvious visual signal that the tube was empty, but I couldn't find a decent one that was really overt, so I settled for a blue one from NDZ performance.

Thanks bro from a florida shark fisherman :) i gotcha a set a jaws on call

Thank you!

590A1 on this end. well done. however, i had buffer from a shell leak into the magazine causing some stiction issues (failure to feed) where the follower did not reseat and i had to butt-bump the weapon to get the remaining shells to fall out of the magazine. some 40rounds later, the problem self corrected. still want to clean it. GUIDANCE please: complete take-down of magazine (spring and follower) ? "Dave Biddle" (reply at the bottom of comments (1yr)) noted his just "unscrews". possible ? thanx, -stev

What a about mag tube ? Is it like the 500 and threads out ? I just got a 590 with a damaged tube I need to change out .

The pieces in side that fall out when the trigger guard is removed are "Cartridge stops"

Good job sir!

thanks just purchased 2day

I just purchased the Mossberg 590a1 Retrograde. It has the 20” thicker walled barrel with heat shield and Walnut furniture. Is there anything I should be precautious about with this variant? Also, thanks for the video! It was easy to learn from it.

Bangin tutorial m8. thx

I'm looking for a compatible barrel that is threaded for choke tunes..... Suggestions?

nice, thank you

What is your action slide 6 3/4 or 7 3/4 ?Seems the barrel is 18,5 inches right?Ask this because want to change my flex forend with Magpul but not sure what action slide to buy? Thank you

The bolt is the hardest part to put back and most important more focus on it would help

I just was able to pick up my 590a1 SBS, when i take the magazine cap off, there is a cap inside. How do i get the cap off?

Good video 🤠

Sir, i can not get that trigger group out with the Magpul stock. I literally can not get it out,. I did it as you suggested....no dice., Suggestions>?

great video that square piece is called a shaft

Good sir, do you have the mossberg rattle with the A1?

Hello. Is the receiver on your Mossberg steel or aluminum?
