As a RS T56 owner, I love this gun. I bought it at AA for 369.99 (later became 299.99 then 429.99). Anyway the gun is all around amazing. Mine came stock with a M130 spring which pushes out 460 fps! The gun also has a High-Tourque motor in it for you FPS kinda people.
Pro: -Nice internals, good size barrel for accuracy
-Real wood furnishing and Metal exterior
-Durable, just like the real thing
Con: -TM mags were too small for the mag catch (I ordered two G&P mags, and they were the mag catch was too big. So I sodered it on the lip and now it fits perfectly)
-High FPS drains my batterys really fast
-has two battery compartments (one in stock one on the top) But the stock compartment has no room, so ur stuck with stick batterys on the top, which makes it harder to put a scope on)
This is an amazing gun, and probably one of the best AK style guns on the market. You could buy a TM and upgrade to real wood, metal, high torque motor, new spring, and high-quality barrel and you'd lose a good $200 in the process of making it as good as the Real Sword
