It seems to stop rolling into the receiver with the new mags, but I haven't battle tested that yet, had nothing but rain for a week now, and everyone else doesn't have bbs (hehehehe I love not having to buy 50,000 bbs every summer!) Yeah I'll wrap the mag with electric tape and I bet it will fit snugger. I've seen the spare parts on evike, I'm just waiting until I can make an order with more thing to make it worth it. Are the mag releases normally so poorly fixed. It just seems that the spring would push it out of place during a game and not hold the mag in correctly. I guess most people glue those bad boys in place?
