@batfurbabies02 yes, that will be a very easy swap and that's all you'll need to purchase.
First you'll need to remove the two cross bolts and clamp blocks on the KMR.
Once you remove those, you'll be able to slide off the rail. Don't be afraid to use some force, the rail has a tight fit on the barrel nut.
It will work best if you use a vise block to hold the upper receiver while you pull the KMR.
Watch the index plate, it will probably fall off the rail once you pull it far enough away from the receiver.
Once you pull the KMR, just reverse the steps to install the new MCMR.
No need to remove the muzzle device, the rail will easily slide over it.
Here's a PDF of the instructions for the install:
