I worked all summer long hauling hay when I was 15 to get my dad to buy me an AR-15 (this was in 1986). What I got was a new SP1, just like the one my cousin had. I still have the lower and the bolt carrier group, but the gun is now a CAR with a Bushy upper. I was watching some movies the other day (it was raining) and in those particular movies were a bunch of m-16 A1/SP1s and it made me long for my SP1 in its original form. I wish Colt or Bushmaster would decide to go retro and re-introduce a SP1 type rifle after the ban ends, kinda like what Colt has done with the Series 70 1911. I doubt this will happen. If the ban does end I'll probably buy a lower for my CAR and restore my SP1 to original form. Would any of ya'll buy an A1 type rifle if it were offered? Just curious.
