"These fit perfectly in the A&K PTWs, feed flawlessly. Only thing is, even with other PTW magazines, is that their BB followers tend to fall out when reloading an empty magazine or accidentally bumped when the follower is sticking out of the magazine. Luckily Evike.com has the MAG aftermarket mag followers that will prevent this from happening. May be a bit pricy for what it does, but i'd rather have a functioning magazine than a magazine that can't work because the follower jumped out.

-Sturdy, rock solid
-Heavyweight, adds a bit of realism
-Great quality metal used for the magazine shell
-EXTREMELY easy to disassemble compared to MAG brand magazines
-Price is unbeatable compared to other PTW magazines

-BB follower is not the best
-Paint wears fast (personal gripe.)

It took so long to get these stateside, but now they're here! Grab um!

Why Mid-Cap Magazines?
Mid-Capacity magazines offer stealth operation by eliminating BB rattle often experienced with Hi-Caps. They feed smoother than Hi-Caps due to their high tension internal spring, similar to a real steel magazine. Since 470 round Hi-Capacity magazines don't exist in real life, a good amount of Mil-Sim players prefer Mid-Cap magazines for an even more realistic type of gaming experience.

Due to the design of all Mid-Cap magazines, they actually function better once you break them in. To do so spray some light silicone oil into the magazine, load and unload it a few times until BB's feed smoothly. This process breaks in the internal spring allowing it to function without problems each and every time.
