Fits my bayonet lug and looks MEAN
Fits a standard bayonet mount as long as it's mil-spec.
It fits over a standard M4 flash hider, but when I tried to use it with a muzzle brake I purchased separately the muzzle brake was a tiny bit too wide for the circular opening on the knife.
So I guess I would say make sure you are using the standard mil-spec bayonet lug and flash hider if you want to make sure it fits on your gun.
The knife looks bad-as*, is super sharp, and comes with a great sheath and holster, very tactical looking.

Great Quality, Low Price. FITS MOSSBERG 590 SP
Fits perfect on Mossberg 590 SP. I bought this because my cheap-o Ebay-onet didn't fit right on my Mossberg 590. The guy at Big5 (where I bought my 590) told me that other people had the same problem with other brands of bayonets and only the Smith and Wesson ones seemed to fit good. The BTA-MALL price beat the Big5 knife clearence price (which is usually extremely low) and they were out of stock at Big5 anyway.
Also note-worthy: It came packaged very well with the knife seperate from the sheath and the blade wrapped in cardboard. (The blade can get scratched if shipped in the sheath because bayonet sheaths usually have something metal inside them that push against the blade to keep the blade from moving around and making noise.
Really sharp, thick handguard, made of very high quality materials.
Nylon on sheath seems a little thin but shouldn't be a problem.

It fits perfect as a bayonet
Bought this for my LWRC M6-SL. It fits perfect as a bayonet. The knife is sharp and not fake as some people might think. You get a case but the case is tight so some paint will come off but other than that it isn't bad at all. I didn't buy this for looks but for practical use. If an intruder comes in the house and charge at me than I'll stick that person with this knife plus you never know you may needed for the zombie apocalypse. Enjoy!!

Not a bad knife for the money
I purchased this bayonet for my Mossberg 590 special purpose. The scabbard is built well and honestly is a little overkill. The bayonet fit on my Mossberg 590 special purpose like a glove and looks intimidating. The knife itself is sturdy and would work just fine if you really had to use it to protect yourself. Fours stars due to not having a full tang blade.
I recently sent this knife back to BTA-MALL because I changed my mind and purchased the Smith and Wesson SW1B Special Ops (on BTA-MALL). The SW1B doesen't have the large barbed/saw edge on the back of the blade. Also the SW1B has a double sided edge.
All in all the SW3B is a pretty good knife but I wouldn't use it as a bayonet due to the large barbed/saw edge.

Man, this thing is awesome. The sheath is half of what makes this rig cool. Hard plastic with a unique qd belt/molly attachment. I can't think of any specific name it could have. It's awesome though. Came with a sharpening stone, cord cutter, and theres even another tool that I haven't even figured out yet. Its been over a year and I still don't even know all the capabilities this thing has. For the price, I don't think there is anything that can beat this rig. Especially with the S&W name on it. Bayonet function works but I will say that it rattles a little bit. This is due to the barrel ring being slightly too large. Either way, buy it!

Love that I can attach it to my Bushmaster M4A3, comes with a scabbard that has multiple ways to attach to gear, from a belt hook to Alice clips and MOLLE snaps. The knife obviously doesn't compare to the quality of SOG or Gerber, yet I don't plan on carrying this bad boy around 24/7 or much less using it for anything more than camping, hiking, and hunting. Blade needs to be sharpened out of the box, but the scabbard has a sharpening stone on the back (How convenient!) Other than that, quality for the price is great! Would buy other tools/blades from S&W in the future!

High Quality Knife
I love the fact that it is a Bayonet knife. It looks so cool and as you see it you know its of great quality. it is exactly like the description and the photos. the blade stays sharp and smooth after using. sharpening is not a problem. I got the item in less time then it said on the listing. very happy with the knife. great service to.

This is not made for a Carbine gas system. It is to short and loose fitting. Otherwise very nice knife.

Pretty good, just not great
Very well built, strong, seems very durable with a good edge on it, it is not very well balanced however, which is its greatest flaw, however it is also a bayonet so if used for its intent, on the end of a gun, that is not an issue, however I do not use it for that, mostly for just random chores and things around the house or camping, overall it is fairly good, not perfect, I have a much nicer knife, however that is also like 4 times the price
the handle could be a bit better, and it is quite heavy
worth the money

I love these S&W knives
I love these S&W knives. Attractive, somewhat functional if a little delusional, like the wire cutter, but really cool stuff. Not a SEAL, but it's cool for all us wannabes. Don't know if anyone serious about what they are doing would use one, but I really like it. I have two.
