I want to put one of these together but I am wondering if I should use a Alum freefloat HG with the thin barrel in order to have decent accuracy, but then I will be giving up much of the weight savings of the LW barrel.  If I could get the LW barrel and A2CAR handguards to shoot at around 2" off of a pack or rest(not a bipod)at 100 yards I would be happy.
Anyone have any advice?  
Any recommendations on a lightweight freefloat tube??

One problem with the standard handguards will be the point of impact shifting.  I owned a Colt lightweight and it was quite accurate (consistant 1 1/2" groups, 100yds) but, the impact would radically shift (6" or more) with different pressure on the barrel.  

Free floating would/should eliminate the shifting POI.
