Just recieved this gun in the mail today, and WOW. Unbelievable build quality, everything feels amazingly solid, handguard has NO wobble whatsoever, RIS came pre-installed, with a slip from airsoft GI that chronod it at 410 out of the box. Battery wires on the crane stock can be a pain to connect until you get used to it. EVERYTHING IS METAL (excluding crane stock and hand guard), so this gun has a very nice weight to it, and looks unbelievably good. My mid-cap magazine was DOA, but the hi-cap feeds nicely and feels very solid.
I would recommend this gun to ANYONE who is looking for a high realism AEG M4.
Almost Entirely Metal
Extremely solid build
Functioning Charging Handle / Bolt Catch
Crane Stock is much better than the battery in the handguard
Almost no wobble on anything on the gun.
Magazine wobbles a bit in the mag well, maybe a total of 3/4" movement from side to side, a slight up-and-down movement, but it still feeds fine
Crane stock is all plastic (except the pin to keep it in its position)
Crane stock wobbles a bit
Delta Ring is very stiff (could also be a pro)
