Hey Guys,

I am a new owner of a Bushmaster XM15-E2S with an A3 upper and a 16" stock barrel with the military birdcage flash suppressor. It has a bayonet lug underneath the front sight post, which clicks into the new USMC fighting knife nicely. However, the bayonet ring's diamater is much bigger than this thing's barrel, so it flops all around.

Is there some sort of adapter that I can get to fill the gap in between the bayonet ring and the barrel? I searched around the sight for awhile and couldn't find anything.

Thanks for the help, and

Semper Fi
