I thought it was something to do with the Kalifornia AWB, AR15 was banned by name so they made them "Sporters"

you might be right about that - not too sure. pages 304 - 306 in BRII go into it but it reallt isn't all that clear. it shows the transitional model and it also says the ATF wanted the firing pin head exposed because with it shrouded it could easily be used in "slam fire" FA mode. And the ATF required that the transitional BC be fully milled off "half circle" so that the "bolt on" sear trip device couldn't be used. All very interesting and about as clear as mud as Colt is shipping SA Rifles with M16 BCs in them now......

Yeah, but the ATF didn't require anyone but Colt back then if that's the case. Bushmaster, et al, didn't do cut out bolt carriers, sear blocks, etc. Might be some stories in 1990-1991 gun magazines about this topic.

Ive heard two stories to why it was done, and both are mentioned here in this thread...
1) To clear the sear block that COLT installed into the lower receiver...
2) To prevent the use of a bolt on sear trip device...
Considering that COLT was the only company to do the half circle carriers, it makes me think it was originally done to clear the sear block they use in the lower...
Scott Ryan or Ekie could probably give the correct answers...
