Unfortunately, it seems the normal AK-74 bayonets available on the internet here don't fit the AK-74M (which has a slightly different bayonet)... so I've had to order one specifically for the AK-74M. Normally when I buy a military rifle I try to also get the correct military-issued components (like sling, bayonet, magazines, etc) to complement the rifle as it would have been used in service. This also adds value to a potential future resale (what I basically intend to do with 9/10 of my guns...)
As for your comments about those who "need guns", I am a collector first and foremost.
