Time for story time with weird Uncle Matt! Way back when I first got tangled up with this group of lovable meat-heads, I gradually got more and more interested in specialized components, specifically a hydraulic buffer unit that lots of folks had various opinions about. So I started doing my research, and found that generally people who had them weren't impressed by them, and in a few cases caused malfunctions of the same type you've described. Against my better judgement, I bought one because I'm the type of knucklehead who likes to make his own assessment. I quickly learned that the hydraulic buffer unit was a useless POS for anything except installing for the purpose of sabotaging an otherwise useful AR.
Here's the moral of the story! When you're doing your research and there's not much feedback on the product, and the feedback that is given is generally negative, you're going to be better off sticking with what's known to work and work well. The SCS is a unsolution to a nonproblem, mark it down as a lesson learned and move on with an effective system that's validated by prevalence, reputation, and history.
