    I am wanting to buy a 20in upper with a free float handguard. The upper I have been waiting for from BCM (http://www.bravocompanyusa.com/BCM-20-Rifle-Upper-Receiver-MI-p/bcm-urg-std 20 mi ss15.htm) has been out of stock forever. PSA just put up a 20in upper(http://palmettostatearmory.com/inde...ped-upper-without-bcg-or-charging-handle.html) that is in stock at the moment. My question is what would I need to add a free float. I know i need a low pro gas block with correct gas port size and obviously the handguard. I want the MI SS15g2. Also what is the difficulty. I have never done a free float just standard. Thanks in advance.

    Not very difficult, you just need the tools. Barrel nut wrench, punches, hammer, vise, and vise block. Also some anti seize or white lithium grease is nice to have.
