A note from Ontario Knife about their Bayonets: "Ontario Knife Company is one of the few remaining American bayonet manufacturers and the sole source of the combat deployed OKC3S bayonet. Complementing our legacy of military issued bayonets, which include the M9 and the storied M7, Ontario Knife's tactical blades include the Air Warrior Program's ASEK survival knife, the Freedom Fighter, OKC's Kukri, and the Navy-issued Mark III."

    Scabbard scraping

    Posted by Andrew on Jul 14th 2021

    The standard scabbard for the M7-B bayonet scrapes off the epoxy coating on the blade due to its sharp retention spring clips, but the blade should be oiled anyway to prevent rusting.

    Ontario M7-B

    The M7-B is a great evolution to the M7 series of bayonets. I usually collect issued military items; I'm not sure if this is an NSN item, but glad I got it. The M7 style of bayonets is very basic and no-frills but the updated M7-B handle fits well in the hand and looks better than expected.

    Best bayonet I've ever seen

    Posted by Stephen Wick on Dec 20th 2019

    I owned a S&W M9 bayonet. After 3 years it actually exploded off my belt into a bunch of pieces during an FTX. That's when I realized what "Made in Taiwan" means... S&W was kind enough to send me a brand new one in exchange for the parts I was able to find on the ground, but I can't depend on a knife that does that. I did some research, and the veterans swear by the M7, and having held it in my hand, and attached it to my AR-15, I can's say I blame them. It feels solid. There's nothing to fall apart. The handle is strong rubber. There's no shaking, rattling or slipping in my hand. It's simple and it just works. Best of all, it's "Made in the USA"!

    Ontario Knive M7-B Bayonet + Scabbard

    Looks like it was moderately used. Positively click attachment to my AR-15 bayonet lug. Bayonet scabbard is average.
