LWRC compatible rails?

I’m looking to get a free float rail for my LWRC M6SL and have come across Midwest Industries as a viable option. Does anyone have experience with how tight the MI rails are to the piston and whether or not I’m wasting my time?

Midwest Industries.

Doro19 are you sure that Midwest industries will be compatible?

Yes. I have them on my LWRC M6

Awesome, may I ask which rail you went with? I looking at either the free float quad rail or the free float rail with add on sections.
