6mmProShop 400 Round SMG Mag Size Airsoft Universal BB Speed Loader (Color: Smoke)

"Not sure if this was meant to also work with gbb pistol mags (i'm using tm hi-capa), but it doesn't work very well. The gbb adapter is too long. Maybe meant for rifle gbb mags. I'm going back to the the cheap speed loader with gbb adapters until I find a large capicity one that works.

"Great loader mine didnt survive long

"Do NOT waste your money on these. My speed loader that came included with a spring gun many years ago works on par if not better than this. Don't waste your money, my friend has the Elite Force EFSL14. In all honestly, save up the extra $25 and get that.

"Has a massive design flaw, the slide that pushes the bbs into the mag gets caught on the bbs in the speed loader which makes it not even worth using. Got it on sale though so it’s alright I just use my 100 round one instead

"Lacks the anti back feed mechanism of the smaller pistol mag style loaders. Instead uses a small O-ring in the nozzle which immediately came out and got jammed in one of my midcaps. Either stick with the smaller pistol mag loaders or upgrade to one of the rotary crank handle or electric ones. Stay away from this one.
