For you all that have replaced your pistol grips with any other manufacturer (BCM, Magpul, Ergo, etc.), how was the fit?

I see a lot of posts that say they don't fit at all on the newer built rifles (in the last couple yrs). I am wanting to change out my pistol grip for a MIAD preferably but would consider others if they fit the best?

Any info from current DD owners that could lead me in the right direction is appreciated...

Thanks
