Its fully TM compatible except for two things. It has a fixed hop up, and its a clam shell design, not the quick take down like the TM P90. However, if you wanted an economical P90 and had left over metal gears its perfect for indoor. It shoots the same as a stock TM P90 which is significantly lower than 300 FPS. Slap in shitty china clone mechbox/parts and your good to go.
