Be careful with those firing pins they tend to slam fire, I would replace them with the updated ones.

Also I think the Bolt Carrier is supposed to have a milled Carter pen to be correct

Nope, you are wrong. Ya might want to do a little research next time. You are thinking of the first year M16 601 bolt carrier group with the fat head firing pin. Very valuable to collectors because they were discontinued. Might have been on some of the first year slick sided Sp1 carriers but super rare. I could be asking a lot more if they were. They did not use a cotter pin originally they used a retainer with a pronged tip but a cotter worked better and was cheaper.

I'll take it, I'm new to this forum so not sure how you do things around here. PayPal G&S? F&F?

I am looking for what would of originally came in a 1976 SP1. I am guessing this is the piece? Do you have more photos you can send me?
