I put the Primary Arms 5X prism sight on the pistol to see how much it would shrink the 100 yard 10-shot group with M855, from the one I shot with the iron sights.

Whataya know, it didn't shrink the group any appreciable amount.

I did use the group to refine the zero.

I'll try some hpbt match, and 53gr VMax to get a better feel for the accuracy potential.

I might just put the irons back on it, and just keep it short and light.
