No standard hand guards will fit until opened up at the FSB.  RRA should be about 1.78" +- for RRA.  The liners do not need to be removed unless using a lead weight.  Then only the bottom liner.
Search "Grandpa" on the Training Forum for more details.

May need to dremel a bit off the guards at the rear as well.  That's what was required to put my new HG on my new RRA freefloat tube I installed on my RRA std 20" upper.
