I ask this because I am looking for building tools. I am wanting to buy one of the upper receiver blocks that is used in a vice when putting a barrel on. Most say fit A2 and A3 upper receivers. Do I need something else or will that work with my RRA A4 flattop?

My upper receiver blocks fits for all A3, A4, A2 and A1 uppers.
Bought from Brownells.

You need barrel nut wrench also. DPMS multi tool is a good choise.

Yeah I plan to get both. I am going to put my 16'' barrel and stuff onto an A2 upper probably. And use the flattop for a longer barreled scoped gun. I just wanted to make sure I could get a block that fit them all. If I had to buy different blocks left and right I wouldn't be saving much money at all.

Forest's site should be required reading for all new black rifle enthusiasts. I've picked up a ton of useful information over there.
