they make bolt on bayonet lugs for AR platforms. however they are usually designed to go where your gas block is located. from your image, it looks like you already have a few items mounted in that location.
I just mounted that one on my Colt M4 ops where I had taken the front sight post off. the post was not square to the rear sight and made zeroing with iron sights next to impossible so I have a compact 3x9 on it. anyway it clamped right on the front and didn't need to even remove the flash suppressor, just be sure to connect the bayonet to get the correct distance from the front before tightening the screws. I have a few bayonets and turns out one style is shorter then the Vietnam era M7 and had to realign the mount so that the distance was correct and the picatanny rail was square. I'll be set once I find the box that I put the aftermarket iron sights in. lol
Hay thanks I ordered one from Midway $67.00 or right around there, I need to find a different bayonet than the one I have The hole is to small to fit my barrel I will have to look through my dads stash I'm sure he has some other's.

You may need a different diameter flash suppressor instead. I've seen some large diameter ones that looked just like the standard AR ones. Until they were side by side, or measured, you couldn't tell the difference.
I just had to try this I had a extra set of 1" scope mounts witch fit my Bayonet I was only able to use the mount on the rear end of the bayonet so it would set forward, I now need to try a mount from a pellet gun or a .22 to see if the mount will fit mt barrel to firmly mount the forward end.
