Mine came in today. Fast delivery.

Sweet! Yeah, they ship same day the times I've ordered stuff. I look forward to your thoughts on it.

Installed the G2S triggers in both last night. Massive, major improvement.

Can the same trigger in two different lowers feel different? I'm wondering if the blem PSA M4A1 lower I have on the 16" is out of spec in some way. Trigger pull with what was in there before felt really wheezy, to the point where I was getting light primer strikes at the range, a first for me with an AR. I thought the parts bin trigger my buddy threw in there was the culprit, and that it would be totally solved with the Geissele, but it has a noticeably lighter/less positive hammer strike than my SBR'ed lower with the same trigger. Also doesn't matter what combination of safety, detent and spring I use, the safety is also mushy and not positive. What gives?
