M4/M16 Flat Top Upper Receiver Assembly for M4 / M16 Series Airsoft AEG

"I got this as a replacement for an upper that broke. Fit perfectly but Evike weirdly sent me one in OD green. Still works fine though.

"Worked Great! No more fixed carry handle on my M733.

Pros:
- Install was quick
- Many new possibilities with sights



Cons:
None

"Great build and quality, does not fit a G&G lower.

"Decent upper reciever for the price. Someone broke our loaner SRC m4, by falling on it and breaking only the upper (lucky me), so purchased this and clean fix.

Pros: PRICE! Decent quality ABS plastic, has enough give that if your company is slighly off it shouldn't be an issue, but will be still be sturdy.

Cons: The rear pinhole connectors need a slight amount of shimming for the pin to cleanly go through. Becareful when assembling because the dust cover WILL fall off if your not careful, this is not an issue when the gun is assembled. Finally the treads for the upper/barrel are just slighly off so the rethread will take a few turns to get it on 'straight'.

All in all especially for the price, and amazing deal.

"Plastic. I didn't see in the description where it stated plastic or metal, but this thing is plastic.
