I have a Colt H-BAR made in the 80's with blue lable on the box.  It has the A-2 type upper, a heavy barrel and I use it seldom if at all.  If you had this gun would you trade it for a Bushmaster with flattop upper, BUIS, free floated front handguard with rail, and fluted barrel?  It is not a question of owning both, the Colt is probably collectable, but the Bushmaster seems more user friendly. I would like to put one of the low power illuminated reticle scopes on a gun like this.  Is the Colt worth holding on to?  Jimmyp
