> a bayonet (or in modern times, more like fastening a knife to the assault rifle) I mean... that is what a bayonet is. There's a reason why military rifles still come with bayonet lugs on them. > a bayonet ... can be nice to have as a sort of last-ditch thing in a close-quarters situation. There are a lot of downsides to a bayonet. 1. It's a sharp knife sticking out the end of your rifle. So if you have to transition to a shotgun or sidearm and it flops down to your side because it's on a sling, it could cut you. It can also cut a teammate on accident depending on what you're doing. 2. It increases the length of your rifle by 4-6 inches. Which is huge when it comes to room clearing. There's a reason why 10"-12" barrel rifles are so popular in that role - it's way easier to maneuver through doorways and around obstacles. It's also weight added to the end of the rifle. Not a huge amount, but 2/3 of a pound can still be a problem. Especially if you're fighting off and on for hours. 3. It takes up space and weight allowance on your belt or vest. It could have been 1-2 extra mags. Most people just wouldn't consider it a good tradeoff.
