RRA upper, US prop marked lower, RRA 6 pos stock, RRA 2 stage trigger and lower parts,  RRA 16" midlength SS barrel, YHM quad rail float tube, Aimpoint ML2,  ARMS 22-68 mount w/full spacer, ARMS #40 BUIS.  I love the rifle but it's a little heavy,  I think I'll pull the barrel and flute it to loose some weight.  Everything went togther great, very tight fit on the reciever halves,  headspace must have been right cause I put 120 rounds through her today and nothin blew upHighly recommend eaglearms and Pete in NH,  both are top notch.

I wouldn't flute it to reduce weight, I would cut the profile down.  Its probably a HBAR profile right now, which means, under the handguards, its .920", and thus is heavy.  Have it turned down to something like a M4, or better yet, pencil barrel profile.  

Is the barrel a lot heavier than you expected or the rest of the gun? I'm waiting on my RRA mid-length stainless to arrive in a few weeks but I'm not sure what to expect from the weight. I'm only using the standard aluminum free float tube instead of a rail though.

I will end up just turning it down I guess,  thats something I know I can do,  fluting is something I've never tried to , it just looks so cool.  anyone have dimesions I should turn it to?

The barrel is the only thing I don't really like,  but it is very accurate,  better than my 20" I sold to build this one.  It was RRA lower with J+T expedition kit
