"With this I can now mount my bayonet on my M4 Carbine. Have you ever tried to mount a bayonet on your M4? Well it kinda makes you wounder why have a bayonet lug there at all. Glad this is available so I can be very effective while I am doing \"Drive By Bayonetting\"."

"I purchased this bayonet lug for my Bushmaster AR-1, XM15-E2S sometime ago (a year or more...do not remember the exact time) and just got around to installing it...The fit was perfect and I do mean perfect. I did not need to do any fitting to get it to work. It works like a charm with the bayonet attached. Definitely was money well spent. Took just a couple of minutes to install and align. Seeing that they do not carry this bayonet lug now I am glad that I purchased one when they were still available."

"Attached this adapter to my M4 just behind the small dia section of the barrel & it perfectly positions the bayonet on the rifle--leaves 6 3/4 inches of bayonet blade extending beyond the end of the flash suppressor. This adapter is rock solid & super easy to install. If you use the light barrel version (smaller ID) on an M4, it will position the bayonet at the very end of the flash suppressor, almost doesn't engage the suppressor."
