OKC 3S USMC BAYONET FOR M16, M4 CARBINE
Review by Arcadio L.
Verified Buyer
I LOVE THIS KNIFE, THE CLIP POINT EDGE IS SHARP, INTERSECTING THE BLADE. THIS IS NOT MENTIONED. THE HEFT THE KNIFE FEELS GOOD IN THE HAND AT DIFFERENT ANGLES.
I WOULD RECOMMEND THIS KNIFE TO EVERYONE. IT IS ONE BLADE THAT I AM PROUD TO OWN AND DISPLAY. THANK YOU OKC FOR YOUR QUALITY AS DEMONSTRATED IN MY BLADE.
These are the real deal.
Review by Jontue A.

This are the real deal OKC-3S bayonet. This is not a finely finished knife. It has a thick, heavy blade and coated in a black, protective, somewhat rough finish. It's made for military use and is for fighting and utility. It excels as a bayonet on my AR-15. Sheath is a three point mount with two heavy duty snaps for paratrooper use. As others have pointed out, it is designed for an AR-15 with a 16 inch carbine barrel and mid length gas block. It will not properly fit a carbine barrelled short length gas block. However, there are adapters you can get for this. Knife came in perfect condition the way a proper military bayonet should look. Very satisfied.
The BEST Bayonet in Military history!

Ontario does it again! Absolutely a beast of a knife! Mine has a fairly hard heat treatment and was a bit of work sharpening and honing it to maximum sharpness. But I got it there and still retains its sharpness after walking, runing while sheathed and using it to process wood. Very pleased with this knife and is indeed a full tang beauty. This knife is designed to penetrate kevlar and I believe there is no stronger bayonet knife out there and this Ontario certainly rivals the Phrobis, Pal, and Buck Bayonets. It is a little pricey which is my only complaint. But then some classic combat knives are as well, but this is a modern design so the price should be lower. It is after all, a bayonet/Combat knife so the range of uses for this knife are limited. I would love to see Ontario make a fine edge OKC3S without serrations, and even a Tanto version of this knife. I'm glad I bought this knife to add to my collection. Some day this knife will receive Legendary status.
Perfect for us OIF/OEF veterans looking to build a clone service rifle we were issued!

Exactly what I remembered when in the service. This is not a knock off clone, it is the real deal! Will definately be using it when killing pigs after dogs catch them in the woods.
USMC issue

This is the exact bayonet you can find in a usmc armory. It comes with the sheath and it also has a sharpener on the back side. Careful not to cut yourself as it is very sharp.
it is razor sharp

Review by Tanya J.

Full tang and the only thing I would change is the over all length. Call me old fashioned but I like a fighting bayo that is the length of my forearm or a little longer for better fending or even just a little longer reach. The only reason I gave it 4 stars is because I feel where the tang meets the but plate the crimp should fill the hole completely. But in true mil spec fashion it is left with a slight gap in a less than half portion. Functions great over all. Love the knife ordering more during a sale.
