APS Full Metal Receiver Set For M4/M16 Airsoft AEGs (Color: Black)

"This thing is great. I say again this is an awesome aeg receiver. The metal is high quality and very durable. The back pin, bolt release, and magazine catch all fit in perfectly. The front pin needs a little push but that is it. Over all this is an amazing upper and lower receiver.

"Purchased this for a knock-off gen 1 APS-Hybrid gearbox out of an Ignite/Black Ops M4 Viper which I purchased broken. The facebook comment about the holes for the body pin are correct, I was able to use the body pins from the M4 Viper just fine.

It has a great, light-weight feel to it and is very durable. I've dropped it a few times and it's held up. The bolt catch works fine with the APS knockoff gearbox. There is a slight issue with the selector switch though; it works fine with one motor grip set up, but on another, doesn't engage properly and will only put the gearbox in Full auto mode (safe works just fine). The charging handle did need a bit of lube to work properly with the gearbox blow-back bolt I am using tho, so not really a con IMO. The dust cover does not want to stay in place, I think the catch on the inside is just weak.

All in all, I would recommend this if you have an APS style gearbox, but not any other.

Pros:
+ Light weight
+ Durable construction
+ Working bolt catch (For APS style gearboxes)
+ Very little wobble in the mag well
+ Excellent mag release (a bit stiff but then works to just soft enough over time)

Cons:
- Body pins holes are not the correct size on the left side of the lower receiver.
- D-Ring threads are a little off
- Selector switch has minor issues with gearbox tightness
- Dust cover doesn't stay in place.
