I want to put my old slab sided SP1 upper on a new DPMS or High Standard lower. What type of pivot pin will I need?

I'm pretty sure that this one will work fine:


It doesn't specify if it adapts large lower to small upper, or small lower to large upper. I'm assuming that it works both ways.

That is exactly what I need. Thank You! The way I read the ad, it goes both ways--I guess it is AC/DC.

For a Colt SP1 (large hole) upper. You can buy a bushing, that makes the upper work on normal riflesht
