AMERICAN TACTICAL IMPORTS GSG-16 22LR 110rd Rotary Magazine (GERMR110GSG16)

Not overly difficult to load but it does take a minute to familiarize oneself to the way it functions. Shoots flawlessly with zero feeding issues. The only failure to feed I had was due to having missed a round during loading and that's operator error, not an equipment malfunction.

The mag wasn't necessarily to hard to load once I played around and looked at it more and I like that it holds more then the standard amount you would get normally when buying the firearm. My only current issue is that it tends to have a feeding problem though this is most likely user error verus something being wrong with the drum mag. So for right now until I work with it more to figure out more about using the item I'm giving it a 3 stars, though once I get it to work right everytime like I've done with my standard mag I would definitely give it a 5 star rating.

Haven't tested what I received yet, BUT I have tested the exact same product before. It works excellently WITH a slight tweak. Has a giant spiral spring inside; you can open the magazine up, just be careful about that spring and/or have the directions to reassemble handy. The tweak: At least for my rifle, as with ALL magazines I've dealt with for 22LR guns, you really need to reduce the spring tension on them, so they feed like absolute butter. Don't worry, they'll still function just fine, from the first bullet to the last. 22LR doesn't need very much tension (pushing force) to operate effectively, what it needs is for the bullet to slide like butter right out of the top. If it does that, you're probably golden on any 22LR rifle this fits into. So, loosen the tension a fair bit (quite a lot on these, actually); otherwise, regardless of the magazine or bullet (I've found the bullet type to not matter, even though they say it does), you'll get a bunch of failure to feeds, and possibly also crush your ammo when it does fail. With that done (you can reduce tension without opening it all the way!), it's an excellent product, and works flawlessly (if you didn't mess up the fake plastic bullet parts on the inside at the top). Hope that helps!
