Ontario M9 Bayonets

[Slater]

Are these regarded as being similar in quality to the Buck-produced ones, or better/worse?

Never seen a Buck M9 Bayo, but I can assure you the Ontario model is mega crap, especially with it's civilian-unfriendly inflated $80 price tag.
To be honest I think the M9 suffers from design flaws, specifically pertaining to it's edge-design, as well as the major problems that come from it being a mil-spec product (T425 Modified, YUCK!).

If you're just lookin' for a pig sticker to throw on your pre-ban AR-15 or Mossberg 590 I'd buy an M7 for about $10.
