Thank you!
Can you please explain why a BCG with forward assist notches would be correct for an early slabside SP1 from 1969 that has no provision for forward assist? Would this configuration be correct for all of the SP1s made around that time frame? |

Colt used what ever it had on hand and was using the fwd assist carrier at that time so used it on the SP1 line as well ,,, this is commonality of parts saves money in the long run for colt.

That may be true in many cases for Colt, but in this case, Colt started cutting ALL carriers with fa notches in 1967 to make sure there was no way any slick side carriers would end up in model 603s |

I can verify this the FA notches. I still have my first AR15, unspoiled and unmodified, a pencil-barrel SP1 Carbine bought off the rack at a local Colt dealer. I think I paid $450 for it, which I thought was scandalously expensive at the time LOL. It has umpteen jillion rounds shot through it and really the finish, bore & chamber have stood the test of time admirably. It has the above mentioned semi-auto BCA with the FA cuts on the side, but is a slick side upperwi/no FA. |

So depending how long those were used, the next carrier in line would have been the C marked serrated carrier. |
