The Third Generation M9 Bayonet incorporates numerous improvements to previous designs and is wholly compatible for mounting on M16A1, M16A2, M4 Carbine and pre-ban AR15 style rifles. Manufactured entirely in the USA, Ontario's M9 is a rugged and dependable performer for U.S. Servicemen around the world. Easy to attach and remove from the belt using either the spring clip or fastex quick release.

The Ontario M9 Bayonet comes with a .235" thick, 7" long blade made of 420 Modified Stainless that has been Sub-Zero Cryo Heat Treated. Black Oxide non-reflective finish is applied to each blade, while the back features milled sawteeth. The handle is tough grooved & textured glass reinforced nylon with a weather-resistant zinc phosphate coated steel guard and cap.

The third generation M9 features an improved scabbard design for greater safety. A quick release universal military holster system has been incorporated for attachment onto web belts, and grip serrations have been added into the scabbard itself. This makes it much safer to use with the attached wire cutter & screwdriver tip.

It fits my mossberg 590 tactical securely. It is bit rattlely when moving the weapon. A single wrap from electrical tape eliminates the rattle just fine.

Item as described... fast and smooth transaction. A+++

I expected a knife of such a price to be tough heavy and a handful which it is. But it does not take an edge easily. I actually had to use a carbide slot sharpener (which I only use for emergency knife repairs) to put an edge on it and it still is not shaving sharp.

I purchased this bayonet for my ar15 just to have one... but love the idea that it has cable cutting ability with the scabbard. Also OKC makes it for our military. Using the scabbard you can completely brake down the knife for cleaning.

The knife is expensive but worth the money. The quality jumps to the eye as soon as you open the box. As a bayonet it fits perfectly on the M4 carbine for those interested by this minor detail. More important to me is that it does more the job as a combat knife. The size of the blade is impressive compared to previous US Army model I have seen. It is more of a bowie than the slime bayonets (like that of the Garand or M1 carbines). Actually Ontario seems to have innovated with their design by improving on the later models of the Kalashnikov bayonet (especially the European ones-- like the East German or Yugoslav models). These are truly more multi-purpose combat knives than bayonets. Their backs are serrated and they have the wire cutter aperture that the Ontario M9 also incorporates in its design. However the M9 blade is much more massive. Overall I consider it an excellent buy.

Perfect fit on my shotgun and the blade seems pretty sharp. Im happy with the edge. Scabbard is well built too. Worth the extra cash

The bayonet I received was in excellent condition and pretty sharp. I will be honing it a bit to my preferred sharpness. The sheath is solid and fits well on the belt. The blade is pretty heavy (would not want to leave it fixed to my AR-15 for a day at the range). Bayonet is solid and good for its intended purpose. I am glad to add this to the kit. Very pleased with Ontario Knife company so far.
