Thank you 👍, solved my issue. Semper Fi....

Whoever designed it was drunk at the time... burp !😂

My 590a1 came with an M9

Where's the EFi mentioned. No real discussion about its functional operation, fuel injectors or ECU? It looks like a manifold tack-on throttle body system not a port injection system. The very restrictive black cover fitted between the throttle body and the air filter will really kill performance. I can't see any performance gains with the mods, nor the inclusion of the antiquated smog air pump system being incorporated into the upgrades. An efficient Efi ECU with oxygen sensor feedback would negate the use of the air pump.

Ha , You drop stuff too. I don't feel so bad.....😁

How many hp does this engine have?

OKC2s - несбыточная мечта 😢 😢😢

I have tried correcting my post below to: " I made handle scales out of black walnut , and a custom leather sheath. " However the edit just won't work. I hope this does.

US ARMY 1968 - 1971. I put the M7 bayonet on mine and it looked very skimpy...........So I bought a large bowie knife blade and a M7 hand guard + butt attachment and custom made a big bowie bayonet for my Mossberg. made I handle scales out of black walnut, and I custom leather sheath. It is so intimidating, I probably won't have to fire a shot. Edit: I tried to correct "made I handle" but it just would not work. I made grips out of black walnut, and a custom leather sheath.

Do you still have the Bullitt Bret?? Thx

Great mod and video. I have a OKC-3S on my M16A4 and heard that it will go on a mil-spec shotgun. Now I know "the rest of the story". Thanks.

Let me ask you, what is your opinion or experience with drop test on the Moss 590 as it was adopted by military and keeping a round chambered?

If it doesn't fit properly, why did they even adopt it in the first place? Wouldn't they have just requested the right dimensions in the contract specifications?

I looked up the GG&G site, didn't have that bayonet sling adaptor in the 590a1 section

man how do you have that mlok pump on there and still keep the heatshield?

Mossberg 590 retrograde looks great with these.

just put a 590S on layaway and ordered a OKC3S bayonet thinking it would work okay, glad i saw your video , going to GG&G now , THANKS !

Why? It’s cool and we can. I love it!

Nothing clears the trenches like a shotgun with a bayonet! A lot has gone wrong if you get within bayonet distance of the enemy with a rifle, and honestly, most rifles these days aren't really good candidates for bayonet fighting. But shotguns are used up close and personal, and it makes sense to have a pointy thing on the end if you get caught without ammo, or just in the process of reloading. I have loved shotguns with bayonets since reading about the Winchester 1897 with that big ass Enfield bayonet in WWI; Germans were so scared of it they claimed it violated rules of war and they were going to kill any American prisoners they found in possession of it. Brutishly effective setup with that OKC bayonet on the end of a 590! I want one!

Hello and good evening Bret Duff. Please accept a hearty Semper Fidelis from this old Vietnam era Navy guy. I both enjoyed your video and found it informative as well. /As to the GG&G shotgun accessories.. well I'm the happy owner of a 1999 production Mossberg 590SP. This has ghost ring sights and I installed a GG&G polished red aluminum follower when I replaced the factory magazine tube spring with a Wolff extra power spring. This allows keeping the magazine loaded for longer periods of time without weakening the spring. I later found that the metal (aluminum) trigger assembly as well as the metal safety switch from the 590A1 will of course fit the 590SP and replaced the factory polymer units. Over time I've made upgrade to most of my firearms always with an eye toward increased reliability/durability and accuracy. I don't get into a "Gucci" gun with pretentious stuff plastered all over it for looks. I just don't need the extra weight. Now a a pointy implement well that Army M9 bayonet fits well on this and it's easy to put on or remove thus far. As to the fore end I initially got a Magpul kit with the buttstock but with my smallish hands and beefy palms found getting a comfortable grip on the Magpul fore end a challenge so I went with Command Arms tri rail unit. I really am impressed with the reliability of the 590 and to date have over 2,000 rounds down range and not a hickup from the shotgun. Be safe Marine. All the best. I'm out

I think I'd rather make a dedicated metal spacer of aluminum billet and bore and turn it on my lathe to fit the mag cap and to the correct OD. . Paint with Flat Black camo paint and run with it.

A bayonet on a shotgun makes total sense in 2022. We have seen the Commie Fascists burn rape and loot American cities. A big knife on the end of a shotgun should send a message.. Stay off my Lawn..If the mob comes for you. I'd think someone is selling a longer barrel nut by now. God bless America.

Perfect, I'm getting one for my 590A1, when I heard it could have a bayonet, I figure "Well, I have to get a bayonet right?" and if I can get the same bayonet I got issued in the Corps? All for it!

I realize this is an older video but I wanted to thank you for this mod. I used the GG&G Sling mount for my OKC3S on my Mossberg 590 and it worked perfectly. I did not need to grind down the Sling Mount but only need to compress the bayonet's handle slightly. Perhaps they've reduced the size. (6 years later). Makes it even more secure and connects/disconnects easily. PERFECT! Thanks again & Semper Fi.

Very informative.

Thanks!

Thank you very mutch!

#18 o ring works great too, wish I had known about this before buying o-rings I don't need!

Shotgun with bayonet is all about deterrence, very intimidating when standing guard.

Right there is my dream shotgun, only with teardrop pistol grip to bring it in closer to the body, those guns are heavy!

The new gen K-bars are nice.. picked up a surplus one very nice buddy of mine had one i was impressed...

Just get a Riser For your Flashlight 313 Until I D-I-E

Bad bad bad the kids picture show is SHOOOW

Firstly thanks for your service! Secondly, I own this same model shotgun, and have the m7 bayonet and was just watching random videos. But what interests me is your use of the magpul forend with the heat shield, can you tell me how you got the two to work without issues? Everything I've seen so far notes that they are incompatible and the heat shield must be crimped and the forend modified for the parts not to rub. What was your solution?

Size 18 rubber O ring

Recently bought a Mossberg 590A1 and that OCK3S looks good. As it happens, I've already got the G&G front sling mount on my shotgun, so - thanks to your video - the compatibility issue seems to be solved and all that remains is to buy the bayonet. Thanks for sharing.

Not blowback, short-recoil, good disassembly vid, very helpful!

marine corps bayonet its meant for the barrel i think

Yes. Big pointy sticks are BADASS! I have the M7 on mine!

Nice! The "button" is called a Detent ball.

Hi can u tell me we’re I can get that bayonet attachment for the mossburg Maverick 88 please thanks

I have 2 1937 VZ24's one stock and one sporterized both in 8mm mauser. Love them!

Don't over think the flashlight position. If you're ever in the position for having to use it in defense, then that light will cast shadows off everything around you. Just accept it. The main thing is that even with the sling on the light will illuminate the room in front of you so that you can know where, what, and who is in front of you.

I know bayonets are kind of an anachronism, but the look of a bayonet on the shotgun is very intimidating and just plain cool!

Put your light on the opposite side and use a pressure switch or a Surefire hand guard light if I remember right the light hangs below the bayonet. Either option would do fine good luck.

I hope the day that I have to “fix Bayonets” on my shotgun never comes.

Nice... That one has a very light colored stock....

Heat it up with a pencil torch, and put some Aluminum Black on it.

An endcap made with a longer "nose" to intercept the bayonet ring (for lack of the correct termonology) would solve the problem.

Learned that you like 45 vs 9 mm.
