Hate to say it, but mounting an optic is a nightmare. I think every idiot out there has proven they can build an AR or modify an AR. That also lends it to every idiot out there assembling AR's, which is why I think AR's at times get a bad wrap. I've had 3 magazine related malfunctions in my AR and 2 stuck cases, all I shoot is Wolf, and I'm probably at or over 2,000 rounds at this point.
