I recently purchased and rec’d the OPSol Mini-Clip 2.0 Flex. The purchase process could not have gone any smoother. I ordered it on a Tuesday morning it was packaged, and sent out that same day. I’m in GA and I rec’d it in the mail on Thursday. 2-day delivery, no shipping charge, no sales tax and you don’t even have to be a ‘prime’ member like with other retailers, great job OPSol TEXAS. Now about the product - I’ve wanted to do some dry run loading and firing of my Mossberg 12ga at home with dummy rounds to test before purchasing any Aguila mini-shells so I decided to purchase the OPSol Mini-Clip along with some 12 gage 1.5” snap caps just to see if everything would work. I’ve had no problems chambering or ejecting the heavy snap caps (they’re brass – not plastic) with the Mini-Clip installed. Haven’t done any actual shooting yet, so the next step is to buy some mini-shells and go to the range. I don’t have any doubts that all will work just fine, but if it doesn’t, I’ll follow up with another review.
