have the gatling bolt-on for two 10/22's side by side. we go thru lots of 22 rimfire ammo with this setup. FUN, and cheap to shoot. Been thru 5-6 mfgr's of mags, and now only use the BX25 from Ruger. The lips wear off the plastic mags too easily, so the steel lip advice is spot-on.....now, for the money go buy the Ruger! get several, so there is less waiting.....and you can keep the barrel warm
I've always seen those in cabelas and wondered how well they'd work. I'm glad to hear that they're working well for you.
