AR-15 ?

I have an older Colt upper with the larger takedown and pivot pin holes is there something that can be purchased so a newer Lower can be attached to this older upper. Most of the newer uppers have smaller holes so I need something to feel the gaps in the upper.

Will this work for both the pivot and takedown pins?

It is only needed for the pivot pin, the takedown pin is a standard size. The Pivot pins are Colt large hole....

I think you need a Reverse Offset Pin not an Offset pin. Maybe, I was a little confused by the post lol

I read it again and it confused me LOL I think I fixed it now I need to attach an old colt upper to a newer lower. The upper has larger holes a than the lower. That is what I was trying to say sorry.

Yeah, that's what I thought you were saying

You would need the reverse pin set

Allows mounting a Colt Upper Receiver with large pin holes to a mil. spec. (small hole) push pin type Receiver.
