Bayonet on M&P15 OR?

[Chicagoguy]

I'm interested in having a Bayonet on my M&P15 OR. Is this possible? I have the troy battlerail on it but dont have the traditional front sight for the bayonet lug to attach to. Since this is my first AR im new to all the options a AR like mine has I dont know if its possible. Any help or ideas for solving this problem will be greatly appreciated....

You may have to switch out your gas block for one with a bayonet lug. I think Yankee Hill may make one. There may be some type of bolt on type bayonet lug that will allow you to keep your original gas block on your MP15 ORC.
