AR Trigger?

[BlueOvalBruin]

Wolf factory Grendel ammo uses large primers.

BlueOval, are those the magnum small rifle or the regular small rifle?

Those were the regular small rifle primers. I bought the primers a year or 2 ago when the wolfs were the only ones easily available. I hand seated the primers so I know it's either overly-hard primers or weak hammer spring. It wouldn't surprise me if the AR Gold hammer spring is a little lighter than normal, but a lot of folks on the brian enos forum have been complaining about those particular primers.
